Throttle Position Sensor: Testing and Inspection
COMPONENTS INSPECTION
E.F.I. THROTTLE POSITION SENSOR
Resistance Inspection.
1. Disconnect the throttle position sensor connector.
2. Using an ohmmeter, measure the resistance between terminals VC and E2.
Resistance:.........................................2.5 - 6.0 kohm
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.
