Component Test

1. Disconnect the TPS connector.
2. Using an Ohmmeter and refering to the TPS Resistance Chart, measure the resistance between the terminals.

Checking TPS Resistance:




TPS Resistance Chart:





3. If readings are not as specified, replace the TPS.
4. Construct an angle gauge from a suitable material according to the demensions given in image.

TPS Throttle Angle Gauge:





5. Set the throttle valve angle to 41° and then at 51° from the vertical position (including fully closed angle 6°).
6. Using an Ohmmeter, measure the resistance between each terminal and compare readings with the Resistance Chart.

Checking TPS Throttle Angle:

7. If readings are not as specified, refer to ADJUSTMENT PROCEDURES and check TPS adjustment.
8. Reconnect the TPS connector.
