Mazda 6 Service Manual: Crankshaft position (ckp) sensor inspection

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)

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

Mazda 6 Service Manual: Antilock Brake System (ABS)
The ABS control unit continuously monitors the speed of each wheel. If one wheel is about to lock up, the ABS responds by automatically releasing and reapplying that wheel's brake. The driver will feel a slight vibration in the brake pedal and may hear a chattering noise from the brake system ...

Mazda 6 Service Manual: Manifold absolute pressure (map) sensor inspection
Note Perform the following inspection only when directed. The following vacuum values are indicated by relative pressure from the MAP sensor. 1. Connect the SSTs (WDS or equivalent) to the DLC-2. 2. Turn the ignition switch to ON (Engine OFF). 3. Select MAP PID on the SSTs (WDS or equi ...
