Hello everyone, I have a code P0141 which is for O2 sensor Bank 1 sensor 2 (after the catalytic underneath the car, I replaced the sensor twice and as soon as I start the car, ABS, TRACT OFF lights turn on "ABS light blinks. I erased the codes many times, pumped 91 octane gas.
"tract off" light turn on right away after starting the car, ABS comes on a minute after, check engine turn on after 5 minutes of driving.
Any suggestions will be appreciated.
Thx

 

Have you checked for a short or open or high resistance in wiring harness or harness connectors?

 

I never thought about it, I'll check the harness and get back.
Thank you.

 

What brand sensor did you use? OEM or Denso work well on Toyota/Lexus
