2006 Jeep Grand Cherokee Question: trouble code po158. whitch o2 sencor do i change?
If all you want to do is guess that the 02 sensor is actually the problem, it's the one 'behind' the cat conv!... Codes are just a tool to use when diagnosing a problem with the vehicle, not an answer to what the problem is!!!... You might get lucky.... Good luck! - pushrod
