    Default Advise on fault code

    Hello got Astra H Z20LER GTC the car runs perfectly however
    Today I was stuck in a traffic jam so I turned on the AC
    Then 5 minutes later the engine was about to turn off and the car with spanner light went ON and the car went into limp mode
    When I got out of traffic jam I stopped the car and turned off the engine then started it and no more warning light
    When I got home I used op com and read the following error code description:
    P1120 Accelerator Pedal Position Sensor 1 and 2 Signal Incorrect Ratio
    But the car then and now is running perfectly

    Please advise is it the beginning of a serious problem or no worries?

    Clean with electrical contact cleaner. Don't use WD40.
