Signal Circuit Inspection

■ Check For Short To Ground In Signal Circuit 

1. IG KEY OFF.
2. Disconnect PCM/ECM and ETC connector.
3. Measure resistance between TPS2 signal terminal of ETC harness connector and chassis ground.

   Specification:  Infinite

4. Is resistance within specification?

   YES 

   • Go to next procedure.

   NO 

   • Repair as necessary and go to "Verification Of Vehicle Repair " procedure.

■ Check For Open In Signal Circuit 

1. IG KEY OFF.
2. Disconnect ETC connector and PCM/ECM connector.
3. Measure resistance between both ends of TPS2 signal line.

   Specification:  Below 1Ω

4. Is resistance within specification?

   YES 

   • Go to next procedure.

   NO 

   • Repair as necessary and go to "Verification Of Vehicle Repair " procedure.
