Have the above vehicle in at the mo. Customer complained of jurking at low speed and certain throttle positions. Using dealer tool fault coded and no fault codes, looked in live data and the thing that stood out was the throttle sensor voltage is 0 volts no matter where the throttle is. Checked voltage at the sensor plug with it disconnected term 1 and 3 showing 5v, plugged it back on and back probed still 5v. Checked term 2 signal wire and 0v, changed sensor for known good one and still the same. Could there be a break in the wire or possibly an ecu fault, had another saxo in today checked that in live data and thats fine reading 0.5v at idle and 4.5v full throttle. Any info would be most helpful.
