VX Down and it's Bad

[Grif]

Does TPS = Throttle Position Sensor or Transmission Position Sensor? If the latter, the symptom is generally rough/hard shifting from 2nd into 3rd as well as incorrect gear display on the dash (Park lit up while you're driving for example).

If I recall correctly, in the past the TPS= Throttle Position Sensor, highly unlikely culprit. Perhaps the TMS=Transmission Mode Switch (aka Neutral Safety Switch according to some part mongers) is term you were looking for?

I assume you're aiming this at the OP, but I'll add that the OEM parts catalog refers to this part as either a Neutral Safety Switch or ASM Switch - Position. Strangely Transmission Mode Switch appears nowhere that I could find. Also, the guys on the Planet seem to refer to this part as a range sensor.

Clear as mud I know.
