You have basically answered you own question.....the Throttle position sensor has died, these are a sealed unit, genuine BMW is the way to go.
my problem still exist...
i scanned it and see the current data... when the engine idle...
and the TPS 0.00V even though i stepped on the gas...
The Air Flow... stays at 518 mm/HG if not mistaken...
and the Air Temperature and engine temperature at 198.5 deg....
what u suggest??
should i change the parts or the DME or the wiring damaged?
what is the rest of the scanner data you have?
O2 sensor voltage?
color of electrodes of spark plugs?
corroded terminals at MAF &/or TPS connectors. or main connector at engine harness.
*TPS voltage be checked by measuring voltage at varied pedal positions.. increase in voltage directly proportional to increased pedal position
*MAF airflow voltage should also vary upwards with pedal position change
*02 sensor voltage should also play between 250mv to 800mv at idle.
... if both are acting erratically... and u have access to a spare, try a different ECU ;-)
... check also CAT-could be partially closed!(always happens. bimmer weakness)
