Hi all

I have an 04 SRT and at around 30K my CEL came on so I took my car to the dealer and they replaced the 02 sensor. At the time, I didn't get the code and all the dealer said was the 02 sensor was bad so I don't know which O2 sensor was the culprit. About 500 miles after the O2 sensor was replaced the first time the CEL came on again so I took the car back to the dealer. This time they daid they replaced the "other" O2 sensor. Since the car was still under warranty I wasn't too concerned and I didn't ask for specifics or much detail.

At approx 40K the CEL came back on again so I checked to see what code was being displayed and it's 0131 (O2 Sensor Low voltage).

Since the car was running fine but out of warranty I just lived with the CEL but it was annoying as heck so I recently decided to try to concur this pesky problem so I just changed the O2 sensor with a Bosch replacement. By the way, the car now has 67K on it.

After I changed the O2 sensor, with the Bosch replacement and cleared the codes, the car ran without tripping the CEL for about two days. I thought i fixed the problem and then "ding" the CEL came back on again and the car is showing off it's lovely 0131 code to me again.

I have done quite a few searches on this forum looking for ideas to help troubleshoot this problem and I have done what others have, e.g replaced the O2 sensor, checked the wiring grounds, etc (no obvious signs of shorts/opens but I didn't buz out the wires).

Does anyone have any suggestions as to what I should try next?

Thank you for your time!
