#1: Misfire - P0262, P0201, still need help! Author: dan106, Posted: Tue Nov 06, 2012 8:37 am ---- Just joined the forum in hope that someone can help with my misfire!
Ive tried, new plugs (bosch), new coilpack, swapped the injectors about, problem doesnt change cylinder.
Im now guessing its a wiring or ecu fault.
Any suggestions of what could cause this misfire with these codes?
Help appreciated!!

Year and engine would be a help to narrowing down possible causes.
You need to know where injector 1 is for a start. THere is a known fault where the washer jet leaks onto the injector plug.
You're new so it's forgivable as you probably don't realise that there are different variants.
#3: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Tue Nov 06, 2012 9:04 am ---- Its a 1.1 03 plate. Arent peugeots and citroens backwards? So cylinder 1 will be flywheel side?
And yeah i read about that, so i swapped the injectors around, but the fault codes remained at injector 1.
#4: Re: Misfire - P0262, P0201, help! Author: Seabook, Posted: Tue Nov 06, 2012 9:13 am ---- yes you are right
cylinder one is gearbox end
#5: Re: Misfire - P0262, P0201, help! Author: macca1411, Location: Westhoughton, LancashirePosted: Tue Nov 06, 2012 9:17 am ---- Yep, you're spot on with them being backward. The codes are generic so depending on the code reader software, it may get confused with number 4.
After doing what you have already done, I'd be looking at the wiring to make sure there are no shorts or bad connections.
Did you clear the codes after swapping everything about to make sure it wasn't a stored code you were looking at?
#6: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Tue Nov 06, 2012 9:21 am ---- Im using a snap on ethos, cleared codes everytime, ive spoke to a mate who works at peugeot, he said there is a common fault with the wiring to the injectors, but because mine has a rubber like coating its the revised version? I couldnt see anything wrong with the wiring, is there a way to check it using a multimetre?
#7: Re: Misfire - P0262, P0201, help! Author: Seabook, Posted: Tue Nov 06, 2012 10:06 am ---- check the injector voltage while cranking; it should be around 12v
or use a noid light
#8: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Tue Nov 06, 2012 11:13 am ---- so unplug the injector and test the plug?
#9: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Tue Nov 06, 2012 12:03 pm ---- Right just turned it over with th injectors out, closest injector to the cambelt not firing, swapped injectors and its still the same one not firing
Info-flash from Peugeot says that #4 get's dribbled-on by the hole where the RHS windscreen squirter fits.
They recomend replacing injector connector harness IIRC.
If this doesn't fix it, maybe ECU or ECU-connector.
#11: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Thu Nov 08, 2012 6:07 am ---- Is there anything else it might be? just that wiring harness is 106+vat, i dont have that much money spare!
#12: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Thu Nov 08, 2012 8:16 am ---- Is the wiring harness for the injectors the same on different models? the nearest scrappy to me doesnt have any 1.1s and i need to know before i pay for a lift up there to find its different!
Help please i need my car back!
#13: Re: Misfire - P0262, P0201, help! Author: dan106, Posted: Thu Nov 08, 2012 10:36 am ---- Went to the scrappy anyway, changed the wiring harness, no difference, codes cleared before start up and the exact same codes after start up.
Gotta be ecu hasnt it???
#14: Re: Misfire - P0262, P0201, still need help! Author: V9977, Location: Athens, GreecePosted: Thu Nov 08, 2012 12:50 pm ---- More and more likely now.
Did you plug-unplug the ECU connector(s) a couple of times?
Don't use spray on them thgough, and disconnect battery properly first.
#15: Re: Misfire - P0262, P0201, still need help! Author: dan106, Posted: Mon Nov 26, 2012 7:50 am ---- Im back, car is still not sorted, eevn tried new ecu!!
#16: Re: Misfire - P0262, P0201, still need help! Author: Seabook, Posted: Mon Nov 26, 2012 10:04 am ---- could be block fuel pipe
did it squish out fuel while cranking?
#17: Re: Misfire - P0262, P0201, still need help! Author: dan106, Posted: Mon Nov 26, 2012 10:15 am ---- Fuel comes out fine of all other injectors, just cambelt side one has nothing, even after switching the injectors about!
#18: Re: Misfire - P0262, P0201, still need help! Author: Seabook, Posted: Mon Nov 26, 2012 10:28 am ---- i would unplug the fuel rail and pipe check for blockage.
also test the harness careful at each pin, make sure the connection is clean as well.
as you used a scrap yard harness there is no guarantee that it is in working order.
#19: Re: Misfire - P0262, P0201, still need help! Author: dan106, Posted: Mon Nov 26, 2012 10:35 am ---- But surely if the pipe was blocked it wouldnt always be the same injector? especially as the closest injector to the fuel pipe is the one thats not firing.
And fair enough about the harness but peugeot wanted over £110 for one, i cant afford to pay that considering it probably wont fix it.
Everything that ive changed hasnt changed a thing, same fault codes and problem everytime!
#20: Re: Misfire - P0262, P0201, still need help! Author: Seabook, Posted: Mon Nov 26, 2012 10:43 am ---- instead of asking i think you should check it. You can't make assumption when tracking down the problems.
Did you said it is always number 4 not firing even after you swap the injectors around?
and if you found out is the harness broken it could be any easy fix if you could find the broken wire/ connection. Re-wiring it should cost penny. If the plug/ terminal is corrode you should be able to swap them by using your old harness.
#21: Re: Misfire - P0262, P0201, still need help! Author: dan106, Posted: Mon Nov 26, 2012 10:53 am ---- I just dont want to risk taking it all apart and getting water in the system as its p**sing down to make it worse.
Yeah as peugeots are backwards it would be number 4, closest to cambelt injector, and thats the strange thing, the diagnostics show cylinder 1 misfire, even though its actually #4 that doesnt fire, this wouldnt make much difference would it?
The new harness was checked before fitting, it seemed fine as its the revised rubber coated loom and none of the plugs were corroded
