Resistance Inspection

1. Disconnect the CKP sensor connector.




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

Specification: Approx. 550 Ohm

- If not as specified, replace the CKP sensor.

- If CKP sensor resistance is okay, but PID value or PCM terminal 21 and 22 voltage are out of specification, inspect as follows.
1. Remove the PCM.




2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.

Tightening torque
7.9 - 10.7 Nm (80 - 110 kg.cm, 69.5 - 95.4 in.lb)

4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST (104 Pin Breakout Box) terminals with ohmmeter leads.
- If there is an open or short circuit, repair or replace wiring harnesses.
- If there is no open or short circuit, replace the CKP sensor.

Open circuit
- CKP signal (-) circuit (CKP sensor connector terminal A and PCM connector terminal 21)
- CKP signal (+) circuit (CKP sensor connector terminal B and PCM connector terminal 22)

Short circuit
- CKP signal (-) circuit (CKP sensor connector terminal A and PCM connector terminal 21)
- CKP signal (+) circuit (CKP sensor connector terminal B and PCM connector 22 to Ground)

3. Reconnect the CKP sensor connector.
