Hey guys been getting a annoying check engine light for P0136 & P0140 Bank 1 sensor 2 Oxygen Sensor for no activity. After replacing the sensor its fine for about 800-1000 miles then it happens again. Ive already gone threw 2 sensors already going on my 3rd. Dont know whats killiing my sensor. Could it be my Giac Flash or Europipe Exhaust?

 

Check for loose connection.

If you need to buy a sensor, let me know. I bought a new one recently but I never use it.

 

Contact me at stef@europipe.be for assistance.

 

Here is the info on the CEL :

P0136 : Left side post cat O2 sensor : Intercore Short Circuit

P0140 : Left side post cat O2 sensor : Interruption of Signal

It is a short circuit or an interruption of the signal so I suggest to check the sensor wire first.
