3.2 EMS problem
I have posted on this one before (about a year ago) - but things have got worse and I could do with some help.
My 3.2 Spider's EMS light keeps coming on under pretty much random circumstances. The fault read-out is:
PO 220 Pedal sensor circuit
P1 221 Pedal sensor 1 circuit
I can cancel out the error codes and re-set. The car then behaves like a Spider 3.2 for anything between 2 minutes and 5 days, then for no apparent reason (no throttle change, gear change, brake, etc - differing speeds) the EMS light will come on again and the brute will go into "help, can't pull the skin off a rice pudding" mode!
I need to find the fault, but this could get expensive unless anyone can advise me if this is a known fault and if so how to rectify it. I presume that here is a potentiometer on the throttle (which might need replacing) which is connected to a server (which might need replacing) on the injection system via the ECU (which might need replacing for ££££s).
So which end should I start??
