  • [Corsa C 2000-2006] Corsa c z12xe revs cutting

    Hi, driving today my revs kept cutting at around 3k and then would come back after 5-10 seconds, I'm fairly sure it's going to be the fly by throttle but I've no fault codes so just wondering if it could be somthing else

    Are you sure it isn't going into default mode? That will limit the engine rpm - feels like hitting the rev limiter.

    The fault code system isn't foolproof. The crankshaft sensor usually doesn't show a code. It may be the fly by wire throttle control as you suspect - in which case it's likely a bad connection somewhere. Check the connections and look for any signs of damage on the wiring. The snag is that the wire can break internally and then it's a pain to track down.

      Anyway to test if it's going to default mode? I didn't expect the crank sensor because it starts first time every time

      I'll check the wiring today and hopefully see somthing obvious
