Throttle Position Sensor: Testing and Inspection

Throttle Position Sensor:

1. Disconnect the throttle position sensor connector.

TPS Check:

2. Measure the resistance between the throttle position sensor side connector terminal 1 and terminal 3.

Standard value: 3.5 - 6.5 K Ohms

TPS Check:

3. Measure the resistance between the throttle position sensor side connector terminal 2 and terminal 3.

TPS Resistance:

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