Hi,
I have been struggling with this problem for weeks and it is driving me nuts. First clearing fault codes and with ignition on (engine off) the throttle blade follows the pedal as it should. No fault codes at this stage. The TPS voltages are verified and runs from .6 to 4.3V and vice versa for sensor #2. I have replaced the TAC module with a new, but no change. The throttle body is new and the car has been running fine until a few weeks ago. No changes made since. I have measured all involved wires in the harness all the way from TB to TAC module and from accelerator pedal to TAC.
I would pay anything (well not anything, but some...) for having this solved. I have attached a log file showing involved sensors in a graph. The log contains two slow push and release of accelerator pedal with ignition only and a few start attempts (where the first probably sets the DTC's. The engine start but dies immediately. I have checked cabling, groundings etc. The car is always indoor in a dry and warm garage.
