CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION[L3 WITH TC]
Caution
• When replacing the CMP sensor, make sure there is no foreign material on it such as metal
shavings. If it is installed with foreign material, the sensor output signal will malfunction resulting
from fluctuation in magnetic flux and cause a deterioration in engine control.
1. Disconnect the negative battery cable.
2. Remove the charge air cooler duct. (See01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH
TC].)
3. Remove the charge air cooler cover. (See01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH

CAMSHAFT POSITION (CMP) SENSOR INSPECTION[L3 WITH TC]
Note
• Before performing the following inspection, make sure to follow the procedure as indicated in the
troubleshooting flowchart. (See 00-00-3 HOW TO USE THIS MANUAL.)

Visual Inspection

1. Disconnect the negative battery cable.
2. Remove the CMP sensor. (See01-40-45 CAMSHAFT POSITION (CMP) SENSOR REMOVAL/
INSTALLATION[L3 WITH TC].)
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.
