The lead arrived this morning and after downloading the sw I plugged in, cleared the long list of codes, ran the car and picked up the following new codes:
P1226 Accelerator Pedal
P0220 Accelerator potentiometer
P1221 Accelerator potentiometer Track 1
I located the potentiometer, its a cylindrical device attached to the accelerator pedal by a rod. Worryingly there are oily finger prints on the electrical connector already !
I read the following values using the diagnostic software:
Potentiometer Track 1 0.737 (closed), 3.813 open before notch*, 4.307 foot to the floor (beyond the "notch*")
Potentiometer Track 2 0.376, 1.919, 2.168
Gas Pedal postion 0.00, 99.61, 99.61
Throttle position 6.98%, 99.98%, 99.98%
*By notch, I mean at the furthest extent of the pedal travel there's like a kickdown position.
Does any of this mean anything to anyone ?? Do I need to locate a replacement potentiometer or does it need adjusting ? The only "problem" I've noted is that the idle speed is not always constant, sometimes need to blip the throttle a few times to make it settle down properly.
Grateful for any help
