Diagnostic Aids

If TCC is mechanically stuck on, vehicle speed is zero, brakes are applied and D2 is selected, TCC fluid will mechanically apply TCC causing an engine stall.

Scan TP signal while depressing accelerator pedal with engine off and ignition on. Display should vary from less than .85 volt when throttle is closed to more than 4 volts when throttle is held at WOT. Incorrect TP sensor values may affect TCC operation.
