Ok so the only CEL i keep getting is P1131 and its driving me crazy. The definition is bank 2- sensor 1 internal resistance too high will someone please tell me what that means and what i have to fix. Thank you.

 

Passenger side primary (in the top of the DP) O2 needs to be replaced.

 

so the o2 sensor on the top of my passenger side downpipe needs to be replaced??? anyway thank you

 

Yup, that's what I said.

 

hey i thought it was the drivers side. cause i shot the same code and changed out the driver side o2 and it was fine. i only say this because on VAST the o2 they are selling say Note: Bank 1 = passenger's side/right, and Bank 2 = driver's side/left.
