Mazda CX-5 Service & Repair Manual: Crankshaft Position (CKP) Sensor Inspection
Visual Inspection
CAUTION:
-
When foreign material such as an iron chip is on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect the engine control. Be sure there is no foreign material on the CKP sensor when replacing.
-
Do not assemble the CKP sensor or change the installation position using any method other than the following. Otherwise, it could negatively affect engine controls, such as the ignition timing and fuel injection.
1. Remove the CKP sensor..
2. Verify that there are no metal shavings on the sensor.
-
If there is a malfunction, remove any metal shavings that are adhering.
Voltage Inspection
CAUTION:
-
When foreign material such as an iron chip is on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect the engine control. Be sure there is no foreign material on the CKP sensor when replacing.
-
Do not assemble the CKP sensor or change the installation position using any method other than the following. Otherwise, it could negatively affect engine controls, such as the ignition timing and fuel injection.
-
If the wiring harnesses or waterproof connectors are damaged, water penetrating the connector will cause a sensor malfunction. To prevent this, be careful not to damage wiring harnesses or waterproof connectors.
1. Idle the engine.
2. Measure the CKP sensor output voltage using the oscilloscope.
-
If not as specified, replace the CKP sensor..
