jose martinez Posted December 29, 2010 Share Posted December 29, 2010 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. Quote Link to comment Share on other sites More sharing options...
intakerGS Posted December 29, 2010 Share Posted December 29, 2010 Did you replace by original/OEM A/F sensors ( Toyota factory or Denso)? I know some aftermarket sensors won't cut it. Quote Link to comment Share on other sites More sharing options...
jose martinez Posted December 29, 2010 Author Share Posted December 29, 2010 I GOT THEM FROM THE LOCAL LEXUS DEALERSHIP ... Quote Link to comment Share on other sites More sharing options...
intakerGS Posted December 30, 2010 Share Posted December 30, 2010 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. Quote Link to comment Share on other sites More sharing options...
jose martinez Posted January 3, 2011 Author Share Posted January 3, 2011 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 Quote Link to comment Share on other sites More sharing options...
