Checking Resistance

NOTE:
For functional testing of the Throttle Position Sensor (TPS), also see On-Board Diagnostics, "Read Measuring Value Block" function 08, display group 002. Testing and Inspection

CHECKING TPS RESISTANCE
- Disconnect harness connector at the TPS.

Throttle Position Switch/Sensor Terminals:

- Connect multimeter (Fluke 83 or equivalent) to terminals 1 and 2.
^ Specified value: 1500-2600 ohms
- Connect multimeter to terminals 2 and 3.
^ Closed throttle position: approx. 750-1300 ohms.
- Slowly operate accelerator pedal fully.
^ Wide open throttle: maximum 3600 ohms.

If either specification is not achieved:
- Replace TPS.
- Check and erase Diagnostic Trouble Code (DTC) memory.
