Throttle Position Sensor: Testing and Inspection
TROUBLESHOOTING HINTS
Hint 1:
The signals of the throttle position sensor are more important fore control of the automatic transmission than for control of the engine; shifting
"impact shocks" are produced if there is a malfunction of the throttle position sensor.
Hint 2:
If the voltage of the throttle position sensor is outside the standard value, check once again after making the throttle position sensor adjustment. In
addition, if there are any indication that the fixed SAS has been moved, adjust the fixed SAS.
