i have a 2001 ford windstar and code po135 keeps coming up i have changed the 02 sensor twice. what is the problem?
First need to know,doe,s it run,or just want run,or run bad?
runs but a little sputtery when idling. no stalling
Have you changed the plug,s and wire, lately?
That code is for a heated sensor, and the sensor it's self may not be bad. Could be the power to it so check fuse(s)
The ECU is confused and doesn't know what fuel/air trim to give the throttle body
no plugs and wires yet but will do and gonna check all fuses.hopefully that can be the problem.thanks
