Throttle Position Sensor: Testing and Inspection
1.
Check resistance between terminals B and D and between B and C.
2.
Ensure a resistance of 3.5-6.5k ohms exists between terminals B and D.
3.
Ensure resistance between terminals B and C is less than 1k ohms with throttle valve fully closed and greater than 2.4k ohms with throttle valve
fully open.
4.
Ensure resistance between terminals B and C increases continuously when throttle valve is moved from fully closed to fully open position.
5.
Ensure resistance between B and C decreases continuously when throttle valve is moved from fully open to fully closed position.
6.
If resistances are not as described, replace throttle sensor.
