#1: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Fri May 27, 2011 10:22 am ---- I went to my local garage today because my EML light has been on a few days. I did not find anything or hear anything wrong.
P0481 Cooling fan control circut - Nothing wrong with the fan it comes on when it should.
P0606 ECU - ????
P0268 Injected fuel quantity cylinder 3 too high - Coil pack? MAP sensor?
P0325 Knock sensor 1 (Bank 1) - Maybe a clean could fix it? Could it cause the overfueling?
P0606 ECU - ????
I had the errors cleared but the EML came back pretty soon. Now I am feeling a bit underpowered; I have noticed a moments delay before anything happens when I put my foot down.
#2: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Sun Jun 05, 2011 6:27 am ---- Can anyone help? I Have borrowed a different code reader and I am getting an injector circuit open error on cylinder 1 and 4 but not 3 as stated with the other diag.
Also it didn't come up as a fault but when i ran a live test I found that bank 1 02 sensor was running 2v; is that not a bit low?
#3: Re: Help me with my diag readout. Author: V9977, Location: Athens, GreecePosted: Sun Jun 05, 2011 6:54 am ---- I think λ-sensor should be reading around 0.5 to 1V.
Check the connections to the injectors if you can.
And/Or ECU connector plugs and sockets might need some contact spray.
But NOT WD-40.
#4: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Sun Jun 05, 2011 7:22 am ---- I will get some contact spray on the plugs. 3 bolts on my engine mount were very loose but I have tightened them. Maybe that caused the knock sensor error?
I tightened a few bolts on the injector rail also but it didn't do anything. I will have a look at the connectors. Could the injectors be at fault as well? I know generally they ether work or they don't.
#5: Re: Help me with my diag readout. Author: V9977, Location: Athens, GreecePosted: Sun Jun 05, 2011 7:27 am ---- I would definately try contact spray everywhere you can.
Sounds like a systemic problem rather than all these things seperately.
Don't bother cleaning the knock sensor, won't do anything.
Hope you get it sorted.

I will do that. if it doesn't work then I might cry.
Edit: Just removed my coilpack to find cylinder 3 plug Is slightly yellow all over and very yellow around the top. Almost like its burning, unless my car has a fungal infection but it doesn't seem likely.
#7: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Mon Jun 06, 2011 5:47 pm ---- Coil pack and plugs changed. That made the cylinder 4 error go away. My dad seemed to think it was arching. EML light came back on so I took the injectors out and cleaned them, the rail, the plugs and that big plug thats behind the engine. As well as all other plugs I could find. I didn't do the ECU though because I couldn't figure out how to remove the plugs and I didn't want to break them.

Oh yeh, ops. No other results apart from what I said above. Cylinder 4 error and EML light still persist.
Other than figuring out how to take the ECU plugs of for a clean and inspection I am lost for ideas now. I have asked a number of my friends who are mechanics but they don't know.
#10: Re: Help me with my diag readout. Author: V9977, Location: Athens, GreecePosted: Tue Jun 07, 2011 6:29 am ---- You have to be really careful with the ECU connectors because obviously the whole engine runs from there.
There are usually 'locking braces' which you have to carefully pull so they will allow the
connector to be unpluged. Then use good quality contact-spray and plug in and out to get cleaning
action while it's still wet.
Allow to thoroghly dry before finaly pluging-in and re-latching the lock-braces.
Battery must absolutely be disconnected!
Do NOT use WD-40!
It won't guarantee to solve your problems but it's good to elliminate possibilities one by one, and it can only
do good to things if you use a decent spray..
P.S. How old is the car and what model?
#11: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 07, 2011 10:11 am ---- I will try that thanks. Its a 1.1 53 plate. Up until now the car has always been perfect.
#12: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 14, 2011 10:32 am ---- Right. the other night the car decided to run on 2 cylinders.
I first pulled the injectors out. I realised that if the coil pack is unplugged the car does not inject fuel. I then plugged it in and tried it and all 4 were injecting. I put it back together and pulled the plugs which were bone dry. How can this be if fuel is going in?
I then tested the coil pack. On two of the wires (grey and I think red but not sure) power was getting to them when the ignition was turned on but then power is lost after a few seconds on those two. Is it supposed to do this?
#13: Re: Help me with my diag readout. Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Jun 14, 2011 10:37 am ---- If the engine ecu detects a misfire on the ignition system it will also stop injecting fuel in to the cylinder affected to protect the cat from being damaged.
#14: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 14, 2011 12:41 pm ---- That makes sense, Going to go to the scrappers tomorrow and chop a coil plug off and wire it in.
#15: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 21, 2011 3:19 pm ---- Still had no joy. Took it to a garage and they didn't know. I will take it to an auto electrician next week and failing that I will burn it.
#16: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 9:46 am ---- They found nothing apart from a badly wired up 02 sensor. They were getting many errors including intermittent ECU fault, a number of injector errors, Knock sensor error and other but I can't remember what he said. Not been to pick the car up yet. The car then stopped giving errors like it did with me before. He said the BSI is probably had it.
#17: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 9:56 am ---- You're non-plexed right?
Very rare for a non-plexed bsi to just go if you haven't been tampering with it
#18: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 10:06 am ---- Thats right. Well what do you think lee? I have tried everything.
#19: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 10:16 am ---- Just seems strange that all the faults are in the engine ECU but yet they are saying its the BSI
What they scanning it with?
#20: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 10:30 am ---- I don't know tbh. He said BSI maybe he was mistaken? What control does the BSI actually have over the ECU?
#21: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 10:34 am ---- The BSI contains the IMMO and that's it.
#22: Re: Help me with my diag readout. Author: namgaj, Location: Chasing Ash, Addaz and Lee........... hopefully catching Addaz and havin fun :PPosted: Tue Jun 28, 2011 10:42 am ---- Its f****d!
#23: Re: Help me with my diag readout. Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Jun 28, 2011 10:45 am ---- Has it been scanned with Peugeot Planet?
If the garage reckon the BSI unit is defective id be tempted to speak to BBA & send them both the engine ecu & the BSI unit for testing / quote to repair.
#24: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 10:50 am ---- If the BSI only controls the IMMO in the car then it should be fine, as the IMMO is working otherwise the car wouldn't start and they wouldn't be able to access the engine ECU.
If it's only engine based things at fault then it will either be some sensor/s or the engine ECU

Than you for that useful diagnosis
Maybe he was mistaken and was talking about the ECU, he didn't really sound like he know what he was doing tbh. Will have to call again tomorrow. I might send the ECU off. How much to BBA charge? I can get hold of a band new ECU for £100, not sure if its blank or just needs coding.
#26: Re: Help me with my diag readout. Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Jun 28, 2011 10:53 am ---- Wonder if the engine ecu connectors are still covered in the w**ky silicone grease Peugeot used on the production line
Might be worth spraying some electrical contact cleaner spray on the connectors.
#27: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 10:54 am ---- New ECU needs to be unlocked or come with the matching BSI and transponder

A dodgy battery spazzed me electrics and blew my windows and central locking but I do not think its related as it was already on 2 cylinders. Not bothered trying to fix those yet.

How much is unlocking? The one i can get is from a pre-plexed i suppose it different though?
#30: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 11:10 am ---- Is it currently on a car that will start?
If so, then I'll tell you how to unlock it for free
#31: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 11:20 am ---- No It was bought for a 1.1 preplexed but it turned out it was not the ECU but the guy still has it.
Would re-mapping it fix it?
#32: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 11:25 am ---- No.
Would need to get this eeprom read in the BSI and the IMMO coding removed
#33: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 11:33 am ---- So sending the ECU in for repair is my only option really.
#34: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 11:35 am ---- Unless you buy a ECU, BSI and get the transponder in the key.
You should get one for £100 or less.
I paid £60 for a GTI one.
#35: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 11:45 am ---- I might try a french scrap yard near me and see if i can get those. Any idea how much an ECU repair is? I have been looking online but I have not found one yet that actually says how much it is. The electrician who has my car said he could send it off but it would cost £70 just to test it.
#36: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 11:47 am ---- Hickleys who are good charge
Petrol ECU = £96.00 inc VAT
Diesel ECU = £108.00 inc VAT
Thats just to test
#37: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 12:05 pm ---- I will ring around some scrap yards then and fit the job lot myself. I am guessing the repair work is not cheap ether so I might as well. I am not going to pay £70-£100 for some to then say they need another £100 or more.
As far as the donor car is concerned, it needs to be plexed and the same engine size? Anything else like the same engine variant (HFX for example)?
#38: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 12:10 pm ---- Yeah needs to be the same electrical system, you need the BSI, ECU and Transponder. Ideally try and get the VIN number too for future reference so you can get the security codes and stuff.
#39: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 12:15 pm ----

Are you refering to plexed/pre-plexed?
And then its just plug and play?
#40: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 12:41 pm ---- yeah needs to be what your car is.
Yeah it should all just plug and play and fire up if you swap it all
KFW engine has a Sagem S 2000 ECU with 3 plugs
KFX engine has a Bosch Motonic MP7.3 ECU with a single plug
Non plexed KFX has a Magnetti Marell 1 AP ECU with a single plug

My engine is HFX just checked with 3 plugs on the ECU so i need the Sagem one.
#42: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 12:56 pm ---- Thought I read you had a 1.4. They are 1.4 engine codes
HFX = 2000-2009 = Magneti Marelli 4.8P = 3 plugs
#43: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 2:57 pm ---- That explains the confusion. Thanks for your help Lee I will let you know how I get on. Although I have not been getting topic reply emails recently don't know about you.
#44: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Tue Jun 28, 2011 3:00 pm ---- No worries mate. Thought I read in another topic you have a 1.4 8v thats why I gave them codes.
I'm the same, only get topic notifications for some threads and not others.
#45: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Tue Jun 28, 2011 3:10 pm ---- I didn't get any for a long time but then I started getting them again. But its stopped again now. I must have 25bhp at best at the moment, but then you get to a hill; I think it has about 1nm of torque. Hopefully that will change soon. I was hoping to get a 1.6 from a guy off here but he has not been online for a while, it might have gone already.
#46: Re: Help me with my diag readout. Author: leigh_boy, Location: EastbournePosted: Wed Jun 29, 2011 4:44 am ---- i had same errorc come up on my gti and an intermiottnt MIL turned out to be plugs and coil pack
#47: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Mon Jul 11, 2011 12:01 pm ---- Plugs and coil pack changed mate.
Okay so I got it back from the auto-electricians. They checked all the wiring and everything was good apart from the o2 sensor. The wires had corroded and broke. They wired it back up and it is now running on all 4 cylinders. How this caued it to run on two cylinders I do not know.
HOWEVER. I am back to square 1 with the EML light refusing to go away. This is the diag they gave me.
Fan unit relay control (fan 2) low speed - Permanent fault
Knock sensor signal - Intermittent Fault
Supply relay control - Permanent fault
Air conditioning pressure - Permanent fault
Knock sensor signal - Permanent fault
Ignition integrated phase detection - Permanent fault
Control Unit - Intermittent Fault
Injector supply signal 4 open circuit, Cylinder 3 injector control open circuit - Permanent fault
If I go back my my first readout it says it was over-fuelling; this has been tested and confirmed.
ECU or could it still be something else?
#48: Re: Help me with my diag readout. Author: Lee, Location: EnglandPosted: Mon Jul 11, 2011 12:28 pm ---- Air con and fan won't turn the light on.
ignition integrated phase detection - thats either related to the injector or the coilpack and spark plugs you fitted, which in turn could be causing the injector fault
You can check the injectors yourself with a multimeter
#49: Re: Help me with my diag readout. Author: Rob2859, Location: HalifaxPosted: Mon Jul 11, 2011 12:50 pm ---- I have tried 3 sets of plugs and 2 other coil packs so I am ruling those out. As I said before they seem to be working fine but I will use a multimeter on the plugs. What power should they be reading?

It was bought for a 1.1 preplexed but it turned out it was not the ECU but the guy still has it.
