Mazda 6 Service Manual / Fuel and emission control systems / Control system / Crankshaft position (ckp) sensor inspection

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.)

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

- 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
