Throttle Valve Problem
Hi, yesterday had engine light come on and car GTV V6 '99 lost power into limp mode, managed to get home. Ran Alfadiag and codes p1120 (Throttle valve pedal plausibility or Throttle valve pedal spring control or Throttle valve actuator protection )and p0120 ( Throttle valve potentiometer signal not valid )came up.
Does anyone have any ideas, sometimes the car will run ok after a throttle reset, key to MAr for 90 secs etc, most of the time returns to limp mode with no power.
Spoke to Jamie Porter suggested white connection from pedal potentiometer. Anyone else had a similar problem, any advice pics etc greatly welcomed as will try and sort out tommorrow.
