207 1.4 petrol anti pollution message

[johntom]

Hi
Our 2006 1.4 petrol gas the EML and the anti pollution message displayed. I have read the codes and got P0170 fuel trim malfunction, p0341 camshaft position and p0131 O2 sensor circuit low volts. Idle speed is smooth, would that rule out air leaks ?
How do I determine the which part is faulty, I have access to live data just not sure how to interpret it ?

Clear the fault codes and drive the car for a day or so. Some of them could be old codes

Hi the codes won’t clear as they are permanent

P0131 is a lambda sensor so the item would need changed that would enable you to delete the code. What are you scanning with?

[johntom]

I’ve used a memoscan and an elm327 both have given the same codes, I do have a Lexia/planet but haven’t dug that out yet.

I'd change the Lambda sensor then clear the codes they are possibly related to the lambda
