Signal Circuit Inspection

■ Check short to ground in harness 

1. IG "OFF" and disconnect ETC Motor & TPS connector and PCM connector.
2. Measure resistance between TPS2 signal terminal of ETC Motor & TPS harness connector and chassis ground. (Measurement "A")
3. Measure resistance between TPS2 signal and TPS ground terminals of ETC Motor & TPS harness connector. (Measurement "B")

   Specification:  Infinite

4. Is the measured resistance within specification?

   YES 

   • Go to "Check open in harness" as follows.

   NO 

   • Repair short to ground in harness and go to "Verification of Vehicle Repair " procedure.
