Need help troubleshooting O2 sensor code (0131) - SRT Forums

BlueNeon04 · 06-30-2009, 07:00 PM

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!

I forgot to mention my car is slow, I mean, completely stock.

Just wondering, but are you getting any other symptoms from the car other than the check engine light? I'm trying to figure out whether or not I'm having the same problem.

No other problem other than the CEL and the O2 code (0131). The car seems to be running fine, smooth idle, acceleration, etc.
