TROUBLESHOOTING PROCEDURES











HARNESS INSPECTION PROCEDURE

SENSOR INSPECTION
1. Disconnect the crankshaft position sensor connector





2. Measure the resistance between terminal 2 and 3.

Standard value: 0.486 - 0.594 K Ohms at 20°C (68°F)

3. If the resistance deviates far from the standard value, replace the sensor.
4. Measure the clearance between the crankshaft position sensor and crankshaft position sensor wheel.

Standard value: 0.5 - 1.5 mm (0.020 - 0.059 in.)

5. Tighten the sensor to the proper torque.

Crankshaft position sensor torque: 9 - 11 Nm (6.6 - 8.1 lb.ft)

TROUBLESHOOTING HINTS
1. If unexpected shocks are felt during driving or the engine stalls suddenly, shake the crankshaft position sensor harness. If this causes the engine to stall, check for poor contact of the sensor connector.
2. If the tachometer reads 0 rpm when the engine is cranked, check for faulty crankshaft position sensor or ignition system problems.
3. If the tachometer reads 0 rpm when the engine is cranked and it does not start, ignition coil or power TR in Engine Control Module (ECM) defect can be considered.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
