Help !!
Hi, new to this so be gentle !! Just bought a SportKa that has the engine light showing - I plugged in the reader and it comes up with P0138 error. I know relates to the (O2 sensor circuit high voltage Bank 1, sponsor 2 - is that otherwise known as lambda sensor ?). I know the previous owner changed it for a new one recently but the fault has re-appeared. Could he have changed the wrong one ?
I have read on other forums that if you don't use original ford parts the voltage varies ?? Also that wires could be hitting he manifold ??
Any suggestions to fix this - the car seems to be running fine apart from this light being on ??
Appreciate any suggestions.
Cheers
Rob
