Hi
I have a 2006 8v 1.4 Peugeot 206 with the full electric throttle.
It will not tick over when cold unless I hold it open on accelerator pedal at about 1000rpm. It then feels as if it is missing and stalls when trying to pull off. If I keep it running for 2 to 3 min all is ok, it ticks over at 850rpm.
I have changed the spark plugs, air filter, thermometer and water temperature sender( temperature was not reading correct)
Once warm the car runs really well and ticks over fine. I have read some codes of the car and come back with
P0135 ----02 sensor
P1161 --- ??
p2101 ----Throttle Actuator Control Range/performance
P01222--- Throttle pedal Position sensor
p1157 ----Vehicle speed sensor
I have not cleared any since servicing the car, and possible some will go now plugs and air filter etc changed.
Any thoughts appreciated

P1161 is linked to the throttle motor.
Could be worth checking the electrical connector to it as it seems to be a common issue on the TU3 engines.
On other PSA models, there is reference to the connector to the BSI being a bit dodgy on RHD models.
The best check would be to use PP2000 and run the check to see if the TB is operating correctly

Thanks for the reply,
with reference to the connections are you referring just to the block that connects to the throttle motor ? I did take the throttle off and managed to open the back where the electric coil etc is in. Not a lot to do in there so I just sprayed with WD40. When I put it back it did feel a bit better.
As I am sure you are aware I could not see any other tickover valves on this body is there anything there that needs cleaning ( I cleaned the main venturie)
I am not into some terminology, however I know what PSA and RHD stands for  but what is BSI and TB stand for ?
Thanks again

Some of the fault codes stored could have been triggered by simply unplugging things while you have been working under the bonnet.
Best thing to do would be clear ALL the fault codes in the memory, drive the car for a day or 2 ( or the diagnostic light comes on again ) then re scan for faults.
BSI = Built in Systems Interface, the software driven computer brain that controls ALL the cars electrical systems over a digital CAN VAN network.
TB would be Throttle Body.

Thanks, never been good at crosswords.
Interestingly my EML (engine management light :-)) has never come on.
I have now removed the codes and will update on what happens

+1 for Mr BSI advice.
So many people chase faults that are old and nothing to do with current problem. Best advice is always clear faults and start from scratch.

Hi
Cleared all errors and been out for 11 mile ride.
Summary is
- it starts really well
- will not tick over unless I hold foot lightly on accelerator. It will tick over at 950 when doing this (may be less than this )
- However if you go to rev up the engine it feels as if it is missing and very lumpy.
- Once it has been kept running for a few min it will rev up ok and will tick over and drives very well
- No EML light comes on
- Error code is P0135 the exhaust sensor
Would the above fault cause above symptoms ?
Thanks

Just took a 'freeze frame' whatever that is ?
Car was just turned on not running. I had started the car which would initially tick over for 5 seconds.
I do not know what data is captured but thought it may help ?

LOAD PCT 84.3

fault code P0135 is saying that your O2 sensor on top of the manifold is faulty, really common fault,
just dont buy a cheap one off ebay, they don't work properly and wear out very quickly, less than 6 months as I found out.

Thanks, would that cause the tickover problem ?

probably, because the ecu isn't getting the correct signal from the sensor it's getting confused
and running in a sort of fail safe mode that is set from the factory.
strange it's not putting the eml light on the dash tho,
it did on mine.

I have read that the EML will only come on if the sensor other side of cat is playing up ?
Peugeot quoted £125 for sender !! Europarts have them for £29 www.eurocarparts.com/e...9ec&000210
Don't want to spend £120 on something that may cure problem. Even if Europarts only lasted a couple of months it would confirm what the problem was.
What do you think

Sorry to steal your thread but my 1.4 seems to have a similar problem. On cold mornings it would lose power when pulling off for 5 seconds or so but picks up again and goes along like nothing happened. I think it has something to do with the heater within the sensors being faulty. Unless you can get a known working second hand one i would go with a genuine part as its a real pain to think you've solved a problem only for it to come back a month or so later.

I can get a 2nd hand one, but price similar to new one from europarts. Trouble is you don't know how long a 2nd hand one would last, but would think a new one would have some guarantee.
My aim is really to find out the cause of problem. If it is cured with the sensor than at least I know what is wrong if and when it reoccurs

I'm not sure, when I got my car the light was on, so plugged it into my mate diagnostic gizmo and it came back with the same fault as yours,
changed the sensor which cost £20 from my local motor factors, but the one I bought didn't come with a plug so I soldered the old plug on, fitted it and the light went off.
6 months down the line the light came back on so I plugged back into my mates machine again and it said o2 sensor again.
he reckons it's because I bought a cheap sensor, maybe that one eurocarparts is a better part because it's got the plug already fitted.
for 30 quid it's got to be worth a go I suppose.
