    Astra Mk5 17CDTI (100) 54 Plate 89K - P1120, P1122

    Hi,

    I hoping someone could give me a diagnosis for the ECN codes P1120, P1122. Just on the way home today when the maintenance light came on and the car lost power. I pulled over turned the car off and then performed the two pedal test. The ECN codes P1120 and P1122 flashed up. Brilliant! Crank sensor was replaced only about 2 months ago, what next???

    Any help welcome!

    Cheers,

    GJ

    Update.

    I had a look around the forums and came to the conclusion that the throttle position sensor was probably on the way out. It had been running like a dog for a week or so. I contacted my friendly local garage who ordered and fitted the part yesterday. £180 all in. Runs fine now and I have a shiny new throttle pedal to boot.

    Any change on the sensor front I will write. Bets on the next one to go?!

    Warning off topic moan.

    Now all I need to find is find a tyre fitter that can balance wheels! How hard can it be!? Everytime I get the tyres changed I have to visit at least 4-5 tyre different fitting shops to find someone who can balance wheels. I gave up last time and went to a crash repair centre who weren't that happy about just doing a wheel balance, but after a bit of pleading, they balanced all the wheels. It drove like new!

    Cheers,

    GJ
