P1135

Recommended Posts

Need some help ... I keep getting p1135 code. I have changed both sensors the one by the firewall and the one by the radiator. Still the check engine light comes on. What else should i be looking at.

Have a look at this topic: p1135 In it a diagram to measure and check the sensor (or wiring harness). It's good practice to reset the ecu by unplugging battery or ecu-fuse, run the car a few miles to see if the light goes off (ECU detects correct readings).

Sidenote:

You need to be sure the AFS you got from the dealer is specific for your car. Later models AFS's are not interchangeable and resistance for heating element is different, which can trigger a CEL.

IT ENDED UP THAT A GROUND WIRE BY THE FIREWALL WAS LOSE. I COULD NOT BELIEVE IT I CHANGED ALL THE SENSORS IN THE CAR AND EVERTHING. ONLY AFTER GETTING SO FRUSTATED I STARTED LOOKING ALL OVER THE ENGINE AND FOUND THIS WIRE LOOSE. AFTER TIGHTENING IT MY LIGHTS WENT OFF WOW SUCH A RELIEF . THANKS FOR ALL YOUR HELP
