The book said - "02 sensor heater circuit short upstream" I just replaced the two upstream 02 sensor but the check engine light came on again. Thanks   Carter Simcoe (Carter) Senior Member Username: Carter Post Number: 2002 Registered: 04-2002 Posted on Monday, March 03, 2003 - 11:25 pm:    unless you clear the code with a reader it will come on again but it will turn off after a few starts   Tbow (Tbow) Member Username: Tbow Post Number: 55 Registered: 12-2002 Posted on Monday, March 03, 2003 - 11:40 pm:    I did clear it.. Like I said, it came back on with this code.   Reed Cotton (Reedcotton) New Member Username: Reedcotton Post Number: 21 Registered: 01-2003 Posted on Monday, March 03, 2003 - 11:45 pm:    You may want to check the connections and wiring. This is indicating a short. -Reed   Carter Simcoe (Carter) Senior Member Username: Carter Post Number: 2003 Registered: 04-2002 Posted on Monday, March 03, 2003 - 11:52 pm:    well you never said you cleared it, you just said it came back on after you changed the sensors. sorry   Tbow (Tbow) Member Username: Tbow Post Number: 57 Registered: 12-2002 Posted on Tuesday, March 04, 2003 - 12:02 am:    Hey no problem Carter.. Thanks for the thought anyway. I also checked the connection and it seemed ok.. I unplugged and plugged it back in and cleared the codes again, but I think it will come back. I was wondering if maybe there was a fuse or something.
