Welcome to the forum amanda,

P1161 (Throttle Position Coherence), potentially a wiring problem, look here:
https://citroenc3owners.com/petrol-citro ... -t248.html

There is a plug and socket under the glove box that causes this problem and can be fixed by removing the plug and soldering the cables together.

This is well worth investigating over buying a new throttle body ;)

Hi,

I was wondering if anyone had any more info on the connector under the glove box.

i.e: What does it look like, how many pins, etc?

I don't want to cut out the incorrect connector now :)

The only info I have is
There should be a four pin black connector that looks like the one on top of the accelerator pedal, remove the plug and solder the wires directly.
Have a look at the wiring to your accelerator pedal and find the plug on it, then find a similar one in the passenger compartment. I think this is a throw back from the left hand drive version, where the pedal wiring had to be extended from the near side to the off side to reach the RHD accelerator pedal.

Hi,

Thanks for the info. I managed to do a throttle body Swap with a mate that also has a C3, so we found out that it was indeed the throttle body. After a good clean, still no luck so I replaced it with a new part from the dealership.

HOWEVER, now the car does not idle when warm. The throttle feels like it is lagging?. When it's cold it starts and idles, no problem.

Was there something specific I was meant to do when I changed the throttle body?

Like:

Clear error codes?
etc..

P.s: After I experienced this problem, I disconnected the battery for 20 mins in the hopes it would enter "sleep mode" and then re-learn the throttle when I started it up. However, this did not make a difference.

Thanks,
Neil

No, but if there was an error code, it its best to clear them after changing parts.

I have had the same prob re cold start ok but stalling as things get warmer. Turned out it was the awkward to fit air cleaner box had distorted the sealing gasket on the throttle body, as always underneath and unseen, causing an air leak.
Took me 12months to solve this one.
