I have a 2002 Durango SLT. The check engine light is on and my code scanner tells me that it's code P0141.

Is this a fix that I can do myself? If so, what do I have to replace and where is that part located on the vehicle.

Thanks.

 

All the info you need is here: https://dodgeforum.com/forum/1st-gen...ine-light.html
But just to help you out, the P0141 refers to 1/2 O2 sensor relay. You have to get under the D and look for at the 4 O2 sensors located on the exhaust pipes. There should be two pre-cat and two post-cat. The relays and sensors you can pick up at any auto parts place. Good luck! HTH.

 

if you have a 4.7 dan is correct, if you have the 5.2/5.9l engine then you will only have one post cat sensor, this code could be a bad relay, but it seems more common to be a bad o2 sensor so it would be one of the pre-cat units
