Crankshaft Position (CKP) Sensor
- CKP sensor is located inside distributor. If a fault is present in CKP sensor, Code 11 may be set in ECM memory. If Code 11 is set, perform appropriate CODE 11 (CKP SENSOR) in TESTS W/CODES article in the ENGINE PERFORMANCE section.
- To test CKP sensor, remove distributor. Leave wiring harness connected. Using a voltmeter, connect negative lead to ground and alternately connect positive lead to 1-degree signal terminal and 120/180-degree signal terminal. See CKP SENSOR INPUT SIGNAL TERMINALS table. See Fig 1 .
- Measure voltages at both terminals while rotating distributor by hand. Voltage should fluctuate 0-5 volts. If either voltage signal does not fluctuate 0-5 volts, check harness for short or open circuit. If no problems are found, replace CKP sensor.
