Citoen C2 Ecu fault clearing

[fflyingdog]

Hi All
My mate has a C2 which is getting a check engine light which Citroen have diagnosed as a defectice cat,he has had the car tested for Co2 and it is well within limits,so what we are proposing to do is to change both the lamba sensors ,but to know if we have sorted the problem we need to clear the latched ecu check engine light,has anyone got any tricks to clear the ecu memory ? i know on some cars you can clear the ecu fault codes by flashing cirtain contacts on the adl port .Any help would be gratefully recieved ,also if anyone has any idea where would be the best place to source a couple lamba sensors that would be great.

Grab an OBD code reader of eBay and reset it via the OBDII port..

www.lambdasensor.com is a good source of sensors..

Nah tried that its latched into the non volatile memory

If you were closer I've got an ELM-327 USB OBDII scanner that should be able to read/clear any errors for you..
