Crankshaft Position Sensor (DIS)
1992 Saturn SC StandardSECTION Crankshaft Position Sensor (DIS)
- If a "Scan" tester is available, scan RPM parameter while cranking engine. If RPM is indicated, crankshaft position sensor is operating properly.
- If "Scan" tester is not available, disconnect crankshaft sensor harness connector. Set ohmmeter to 2-k/ohm position, measure resistance across sensor terminals. Resistance should be 900-1200 ohms.
- Set voltmeter on the 2-volt AC scale. Crank engine and measure voltage across sensor terminals. Voltmeter reading should be .1 volt or greater. If resistance reading is not as specified or sensor does not produce a voltage reading, repair faulty wiring or crank sensor.
