[Warning Light] Fault Code P1161

[AshleyP]

Hi,

Citroen Berlingo 2006, 1.4 Petrol, 65k miles.

Just had the yellow engine management light come on, and my OBD II scanner reader is showing code P1161, but I can't seem to find too much about this code. I have cleared the code now, the van seems to run ok at the moment and the code has not reappeared yet.

Any guidance would be greatly appreciated.

Thanks.

P1161: EGR throttle position copy signal : Valve jammed.

This is the official definition from Citroen.

Thank you.

Could you possibly give me some further guidance as to how to check/correct this fault, please?

You'd have to locate and clean / test / repair the EGR valve, it must be somewhere between the exhaust manifold and intake. No idea exactly where on the petrol engine though.

Normally this is a diesel fault, less likely in a petrol engine as they don't produce the sticky gum that diesels do. But, not impossible. They still often have EGR valves but I don't know the Citroen petrol 1.4 to that detail I'm afraid.

I never heard the old (2006) petrol PSA engines to have an EGR valve. I have a PSA 1.6 (2007) and it certainly does not have one. I'll give that is 1.6, but not that extremely different than the 1.4 from that age. There is always a first of course.

I would be inclined to think that the code reader is misreading the fault or something of that nature. If I were the OP, I would try Diagbox/Lexia before starting looking at where the EGR valve might be.

My earlier 1.4 has the same engine and there is no EGR - I'd ignore the code as an issue if it doesn't come back and the engine is running well!

There you go, another reason not to use generic code readers on Citroen's.

I must admit I'm not so clued up on petrol engines having had nothing but diesels for 20 years.
