Put few posts up recently & aint had much reply but hoping this shall clear problem up, found out that the check engine light is coming on because of an error code 32 which is the A/F sensor, how can this be as have just fitted a brand new bosch universal lambda sensor! it was £38 will i need to shell out for the genuine subaru part to stop check engine light coming on again, if any help its a 51plate impreza & ej201 engine.
Hopefully some1 can help me

 

Spooky as.............

 

I have done the same put new sensor on and when checking fault codes it always comes up with code 32. Car drives fine tho and cel light never comes on, fitted sensor over a year ago.

 

Have you reset the ecu, cause if not it will continue to be on its memory and keep showing up

 

I do mine regularly and it still comes up.

 

yeah reset the ecu but would not reset? flashes up the fault code, iv a very slight hick on tick over so spark plugs & leads were changed but still there, could it be a maf or coil pack problem which is given the lambda sensor cause to come on?... what i dont understand is that when new lambda sensor was fitted it didnt jump voltages it stayed at 0.3milli volts??? desperate to get to bottom of this asap
