2. IGNITION "ON", ENGINE "OFF"
3. Measure voltage between terminal "1" of the sensor harness connector and chassis ground.
A. Specification: Approx.12 V




4. Is voltage within specifications?
YES
1) Go to "Component Inspection" procedure
NO
1) Check for open or short in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure
2) If signal circuit in harness is OK, Substitute with a known-good TCM/PCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and go to "Verification Vehicle Repair" procedure.
