■ Check short to ground in harness 

1. IG "OFF" and disconnect ETC Motor & TPS connector and ECM/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 ground terminals of ETC Motor & TPS harness connector.(Measurement "B")

   Specification  : Infinite

4. Is the measured voltage within specification?

   YES 

   • Go to "Component inspection " procedure.
