Sensor Inspection

Throttle Position Sensor Connector:

1. Disconnect the throttle position sensor connector.

Throttle Position Sensor Testing:

2. Measure the resistance between the throttle position sensor side connector terminal 1 and terminal 4.

- Standard value: 3.5k - 6.5k ohms

Throttle Position Sensor Testing:

3. Using an analog ohm meter measure the resistance between the throttle position sensor side connector terminal 1 and terminal 3.
4. Slowly open throttle valve to full open position.

- Resistance should change smoothly.

5. If the resistance is outside the standard value or if it doesn't change smoothly replace the throttle position sensor.
