My car has been going into limp mode intermittently with the "Engine systems fault, park brake fault, DSC unavalible" I found the TPS, and put in the replacement, however the car is now constantly in limp mode. It was intermittent before, and now I am completely out of ideas, with a practically useless car.

Sorry to hear about the trouble.

I seem to recall a TPS calibration sequence.

Something like: key on II, depress throttle 3 times slowly, key off. Start car.

Please search forum for confirmation.

Maybe this will help; I hope this leads to success.

Also seem to recall that the TPS power connectors can be brittle with age; may be worth a look there as well.

Thanks
