Pete My thoughts are that if the ECU is not happy with the O2 sensor heating circuit ( i.e fault code ) it will quite possibly ignore any o2 information from it and work in a default mode. I don't know the ECU strategy on this particular model, but have certainly experienced this on other brands. I think you have no option but to address the heater circuit fault code. Cheers Aidan |
