goldman88 Posted January 22, 2015 Share Posted January 22, 2015 Recently I have been getting a P0031 code which translates to "Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 1 Sensor 1)". Guess with time these things occur. However, after some thought and research I was just wondering if the issue is more than just regular maintenance. About 3 weeks before the CEL appeared to indicate the fault, I used a can of BG44K in a full tank of fuel. It is purported to be O2 sensor safe [says would not damage anything]. However, I saw a couple of people online stating O2 sensor/CEL issues after using. There s not enough evidence to me to suggest a strong correlation; however, I was just wondering if anyone else has/had the same issue. Link to comment Share on other sites More sharing options...
Idontcarrrrre Posted January 22, 2015 Share Posted January 22, 2015 have you replaced the 02 sensor yet did issue go away? Link to comment Share on other sites More sharing options...
goldman88 Posted January 25, 2015 Author Share Posted January 25, 2015 No, I haven't changed the sensor as yet. Just asking around to see if anyone has a similar experience with the use of the BG44K. Link to comment Share on other sites More sharing options...
