CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L3]

BME014018220W01

  Note

  • Perform the following inspection only when directed.

## Resistance Inspection

1. Disconnect the CKP sensor connector.

2. Measure the resistance between CKP sensor terminals A and B using an ohmmeter.

  • If not as specified, replace the CKP sensor.
  • If CKP sensor resistance is okay, but RPM PID value is out of specification, perform the "Circuit Open/Short Inspection".

Specification

  400-550 ohms

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3].)

2. Inspect the following wiring harnesses for open or short. (Continuity check)

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the harness.
  - CKP sensor terminal A (harness-side) and PCM terminal 2D (harness-side)
  - CKP sensor terminal B (harness-side) and PCM terminal 2G (harness-side)

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - CKP sensor terminal A (harness-side) and power supply
  - CKP sensor terminal A (harness-side) and body GND
  - CKP sensor terminal B (harness-side) and power supply
  - CKP sensor terminal B (harness-side) and body GND
