ok guys i need help my pre-cat sensor went out and i replaed it and i cleared my check engine light and it keeps coming back on and i checked the fuse and i doubt that the sensor is bad anyone eles had this problem and if so what did u do.....

 

Have you had the cat checked? And have you checked this? http://dodgeram.info/tsb/2000/09-05-00.htm.

 

no i havent had the cat looked at i mean i have heard if u hit it with a hammer and hear it rattling its going out but i did and it made no sound... and no i havent check for the P. Leak yet im going to but i dnt have the vaccum gauge

 

Plenum oil leak....I got the same thing, O2 sensor code, changed it and it came back until I fixed the plenum.

Check the DIY section. Couple in there (look at the front 2nd gen page for the link) that explain how to do it, if I remember right.
