  • [Corsa D 2006-2014] 2007 Corsa D Engine Light - O2 Sensor?

    Hi There,

    I have a 1.2 2007 Corsa D, which has just shown the engine warning light. I've used a diagnostic tool which has returned three codes:

    p0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)
    p0138 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
    p0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

    The front sensor (engine bay) was replaced about 6 months ago, but I think sensor 2 is the one located in the exhaust after the catalytic converter. Would my best first step be to replace the O2 sensor there?

    Thanks
Working...
