Throttle Position Sensor: Testing and Inspection

ON-VEHICLE INSPECTION







1. Inspect the throttle position sensor function.
2. Connect the TOYOTA hand-held tester to the DLC3.
3. When turning the throttle linkage to the full open position, check that the throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA shows the standard value.

Throttle valve opening percentage: 60 % or more

If operation is not as specified, check the throttle position sensor, wiring and ECM.
