Crankshaft Position Sensor: Testing and Inspection

CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L3 WITH TC]

Air Gap Inspection

1. Verify that the CKP sensor is securely installed.

2. Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley and the CKP sensor.






- If not within the specification, inspect the plate projections for cracks or bending.

- If there is any malfunction, replace the plate.
- If the monitor item condition/specification (reference) is not within the specification, even though there is no malfunction, carry out the "Circuit Open/Short Inspection".

Air gap
- 0.5-1.5 mm {0.02-0.05 in}

Visual Inspection

1. Remove the battery cover. Removal and Replacement

2. Disconnect the negative battery cable.

3. Remove the CKP sensor. (See Service and Repair.)

4. Verify that there are no metal shavings on the sensor.

- If the monitor item condition/specification (reference) is without the specification even though there is no malfunction, carry out the "Circuit Open/Short Inspection".

Voltage Inspection

1. Idle the engine.

2. Measure the CKP sensor output wave pattern using an oscilloscope. (See Component Tests and General Diagnostics)

- If not within the specification, replace the CKP sensor. Service and Repair
