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.
