Signal Circuit Inspection

■ Check For Short To Ground In Signal Circuit 

1. IG KEY OFF.
2. Disconnect PCM/ECM and APS harness connector.
3. Measure resistance between APS2 signal terminal of APS 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 APS harness connector and PCM/ECM harness connector.
   3. Measure resistance between both ends of APS2 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.
