Hi all,
I'm new on here so hello to everyone
I was after a second opinion on a vehicle I have a job on with at present. I think i've nailed what it is but there is another factor too.
Its an Agila (Vauxhall) which from the part numbers shares the same throttle with the Corsa of the same era. I have codes P0120 which comes up on the ethos as related to the TPS, and P0220 which comes up as an issue with the Pedal switch.
The throttle switch seems to be functioning correctly and the volts are alternating between the 2 switches as they should, the TPS will also do this for a minute or so if I clear the code, then return.
The voltage for the TPS/Actuator is there as well and the throttle works and revs until the code comes back, then the vehicle has correct voltage on the pedal when pressed but the TPS voltage will freeze at 4.2 volts on one side and 0.8 on the other side, and will no longer react.
The Elephant in the room is that the car was reverse polaritied with jump leads, and although the main 80 amp fuse blew and I can't find any other damage, this is when the issue began with the throttle. I know they are on the same feed from the ecu, but if I clear the code while the engine is running I get the throttle back instantly? so i'm leaning towards a bad actuator.
But if anyone has anything else they could suggest, that would help me a great deal.
Thanks.
Andy
