    The wife has an 06 plate 1.6 16v SXI Astra H and we have noticed recently that the car seems to judder a bit and is holding back on power. I have since purchased Opcom and done a scan and the following fault codes have come up.

    P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
    (00) - Present

    P1116 - Coolant Thermostat Valve Circuit Low Voltage
    (06) - Present

    I did change the thermostat on the car middle of last year as it was shot and since changing it, its made a huge difference, however the fault for it is still there even though I have cleared the codes, the above two keep coming back and he EML stays on.

    Any help would be much appreciated.

    Thanks in advance.

    Hi Jase

    Happy New Year to you too, hope you are well?

    Thanks for looking into this, ive joined a couple of Vauxhall Forums, but getting no joy at all!!

    I will have a look at the fuses and possibly replace the 02 sensor and see if that makes a difference, do you think that would cause the car to judder??

    If it keeps coming up it needs replacing anyway but I would assume the juddering is down to that,they measure oxygen so if fecked then your ecu is being given wrong data
