NOTE: Check for open or short circuit in harness. Refer to "SIGNAL WAVEFORM & DATA " in the "General Information" procedure

Check for short to ground circuit
1. Ignition "OFF"
2. Measure resistance between terminal 2 of the APS harness connector and chassis ground
  Specification : Infinite
3. Is resistance within the specification?
  YES
  - Go to next step
  NO
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
Check for open in signal circuit
1. Disconnect ECM connector
2. Measure resistance between terminals 2 of the APS harness connector and 20 of the ECM harness connector

3. Is resistance within the specification?
  YES
  - Go to TERMINAL AND CONNECTOR INSPECTION
  NO
