Throttle Position Sensor: Testing and Inspection

THROTTLE POSITION SENSOR
a. Resistance inspection.
1. Disconnect the throttle position sensor connector.
2. Using an ohmmeter, measure the resistance between terminals VC and E2.
Resistance: 2.5 - 5.0 k (Ohm)

3. Check the change of resistance between terminals VTA and E2.




Change of resistance:
The resistance value increases in proportion to the throttle lever opening value.
