Here (attached) are the summary descriptions of the 3 codes from the FSM. The fifth attachment is the wiring diagram referenced in relation to the P0136 and P0141 codes.
I thought about offering exactly that same opinion, but ...Replace your O2 sensor, all your codes may go away.
Well I took the truck to autozone to have it scanned,came back with...
p0136 heated o2 sensor bank 1 sensor 2 circuit fault
p0141 heated o2 sensor bank 1 sensor 2 heater circuit malfunction
p0120 throttle/pedal position sensor/switch "A" circuit
I haven't noticed a smell comming from the exhaust and the fuel milage hasn't seemed to tank so does this mean it's just the sensor?
If so what one is it? I've looked around but can't seem to find a diagram...guess I need to pick up a sevice book :doah:
As for the TPS code...the truck will sometimes surge when at a stop light other than that I haven't noticed anything....can the TPS be adjusted,or should I just spring for a new one?
the truck is a 2002 taco with a v6 and an auto....It's only got 119,000 on it
