I have the manual for this car and have had a P0141 code. Problem is that I can't find the electrical diagram showing info on the downstream O2 sensor heater & or cct. Manual only shows 1 O2 sensor for vehicles to 1995. Can someone help me with this, I just bought the manual for this purpose and i can't seem to find what I need. Am I to assume that there is a pwr supply and a heater relay control for the O2 sensor heater. In other words replacing the downstream sensor may not fix the problem ?
Model is an SL1, 1.9L SOHC engine, approx. 140,000km

Hi Peter,

Contact one of our tech service reps at research@haynes.com. Give them the info about your vehicle (again, sorry) and the manual number that you are using. They'll do what they can to help you.

Thanks for using Haynes manuals.
