Throttle Position Sensor: Testing and Inspection
INSPECT E.F.I. THROTTLE POSITION SENSOR
a. Check the resistance.
1. Disconnect the throttle position sensor connector.
2. Using an ohmmeter, measure the resistance between terminals VC and E2.
Resistance: 2.5 to 6.0 kOhms
3. Check the resistance variation between terminals VTA and E2.
Variation of resistance:
The resistance value increases in proportion to the throttle lever opening value.
If the result is not as specified, replace the E.F.I. throttle position sensor.
