CAMSHAFT POSITION (CMP) SENSOR INSPECTION[LF, L3]
NOTE: Perform the following inspection according to the DATA MONITOR function (indicated by monitor item from here onwards).
Visual Inspection
1. Disconnect the negative battery cable.
2. Remove the CMP sensor.
3. Verify that there are no metal shavings on the sensor.
-
If the monitor item condition/specification (reference) is not within the specification even though there is no malfunction, carry out the "Circuit
Open/Short Inspection".
Voltage Inspection
1. Idle the engine.
CAUTION: Water penetrating the connector will cause sensor malfunction. To prevent this, be careful not to damage the wiring
harnesses or the waterproof connector so as to cause water penetration.
2. Measure the output voltage using a oscilloscope.
-
If not within the specification, replace the CMP sensor.
-
If the monitor item condition/specification (reference) is not within the specification, even though the voltage is within the specification, carry
out the "Circuit Open/ Short Inspection".
