 Subject: O2 sensor Problem
IP: Logged
Message:
Hi!
I have a 1996 Dak V6 3.9L. 87,770 miles. I have been battling the check engine light and the O2 sensor. I has the original O2 Sensors in it. It started with codes 51 and P0171. I put in a different upstream O2 sensor. Now it throws a 21 & P0132 code. It means O2 sensor # 1 Shorted HI. So, I put the old one back in, and it shows the same code, even after I disconnected battery to reset computer. I am confused. Any IDEAS??!!
Please HELP!!!!
Thanks!
Frustrated!!!!

Bad or intermittent connection in wiring harness is one possibility.

Take it in! Have dodge dealer hook up their scan tool. With gas as expensive as it is and sensors $70+ better to be sure. You'll have to pay the diagnosis fee ($100+or-) I think its worth it. By the way, make sure you replace them with parts from the dealer if you do it your self. I've put in I don't know how many aftermarket sensors including the O2, most last a week or so before the code comes back. Spend the money, get the genuine part!
