    Nissan Micra 2003 K12 CR14DE engine. Archived Message

    The car will start and idle fine, When we press the throttle pedal the engine will slowly pick up to 2000rpm and stay there. Fault light shows all the time.

    Codes

    P2122 Throttle/pedal position sensor/sw D (low input)

    P2138 Throttle/pedal position sensor/sw D/E (voltage correlation)

    Read with autodiagnos, When attepting to clear the unit says they are erased but the re appear straight away.

    Checked the signals from the pedal sensor and all seems to be reasonable although I cant find any data so cant be 100% sure. Cant chack at ECU (as I have no pin data)

    The Live Data on the Autodiagnos looks very suspect with a large majority of sensors showing 0volts or 0 percent, Could be an ECU fault but im not convinced the Autodiagnos is 100% up to speed with this system and am reserving judgement.

    Has anyone had similar problems with this system? Any ideas? Really stuck with no information and equipment im not convinced is working properly with this aplication (althoug I must say on the whole im very happy with the autodiagnos)
