- Crankshaft position sensor coupler (from the wire harness)
2. Check:
- Crankshaft position sensor resistance
Out of specification → Replace the crankshaft position sensor.
Crankshaft position sensor resistance: 336-504 Ω at 20°C (68°F).
a. Connect the pocket tester (Ωx100) to the crankshaft position sensor coupler as shown.
Pocket tester: 90890-03112.
Analog pocket tester: YU-03112-C.
Positive tester probe Gray «1»
