Dannyg Posted December 12, 2017 Share Posted December 12, 2017 Hi All ive got multiple O2 sensor error codes coming up, but its not the sensors at fault my garage reckons it could be something to do with the wiring and suggested they carry out a pin-out test, i have found info on what each pin does, and a diagram but my garage have said there is no Bank 1 sensor output pin would something like this be on the main ECU wiring diagram? has anybody had this before? and can any body point me in the right direction thanks Dan Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted December 12, 2017 Share Posted December 12, 2017 What codes are you getting? Also what year and model is your car? What adverse running issues are you having? Quote Link to comment Share on other sites More sharing options...

Just been going through original build on this car and read that it has berks hfcs on it, so its actually a common fault, will a remap get rid of the eml light for these codes?

ZMANALEX Posted December 17, 2017 Share Posted December 17, 2017 If it is the Berks that are at fault then an up rev should fix the problem as they can be turned off when doing the tune. Quote Link to comment Share on other sites More sharing options...
