Throttle Position Sensor: Testing and Inspection
THROTTLE POSITION SENSOR (TPS)
The TP Sensor is a rotating type variable resistor that rotates with the throttle body's throttle shaft to sense the throttle valve angle. As the throttle shaft
rotates, the throttle angle of the TP Sensor changes and the ECM detects the throttle valve opening based on the TPS output voltage.

TROUBLESHOOTING HINTS
1. The TPS signal is important for the control of the automatic transaxle. Shift shock and other trouble may occur if the sensor is faulty.
2. If the idle condition or acceleration is abnormal, check the TPS connector. (When the TPS connector is not connected properly, the current data on
HI-SCAN can show that the idle state remains off, although the accelerator pedal is released. This results in the improper idle or acceleration.)
3. Input voltage from throttle position sensor is below 0.1 V or above 4.7 V when ignition switch is turned on.
