Crankshaft Position Sensor: MPV

  1. Disconnect Crankshaft Position (CKP) sensor 2-pin harness connector. Using DVOM, measure resistance between terminals "A" and "B". Resistance reading should be 315-385 ohms. If resistance reading is as specified but PID value is out of specification, go to next step. If resistance reading is not as specified, replace CKP sensor. See CRANKSHAFT POSITION SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL, OVERHAUL & INSTALLATION article.

  2. Open Circuit Inspection

    Disconnect PCM 104-pin harness connector. Connect 104-Pin Breakout Box (49-UN01-130) to PCM harness connector only. Using DVOM, check for continuity between following terminals:
    • CKP sensor harness connector terminal "A" (Gray/Yellow wire) and breakout box terminal No. 22 (Pink wire).
    • CKP sensor harness connector terminal "B" (Black/Pink wire) and breakout box terminal No. 21 (Green wire).

    If continuity is present, go to next step. If continuity is not present, repair open circuit in suspect wire or replace wire harness. See appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS.

  3. Short Circuit Inspection

    Check for continuity between following:
    • CKP sensor harness connector terminal "A" (Gray/Yellow wire) and power supply.
    • CKP sensor harness connector terminal "A" (Gray/Yellow wire) and body GND.
    • CKP sensor harness connector terminal "B" (Black/Pink wire) and power supply.
    • CKP sensor harness connector terminal "B" (Black/Pink wire) and body GND.

    If continuity is present, repair short circuit in suspect wire or replace wire harness.
