Camshaft Position Sensor Removal/Installation
Refer to the Camshaft Position Sensor Removal/Installa-
tion in the Electrical System chapter.
Camshaft Position Sensor Resistance Inspection
Refer to the Camshaft Position Sensor Inspection in the
Electrical System chapter.
If the reading is within the standard, check the peak volt-
age (see Camshaft Position Sensor Peak Voltage Inspec-
Camshaft Position Sensor Peak Voltage
Refer to the Camshaft Position Sensor Peak Voltage In-
spection in the Electrical System chapter.
If the reading is within the standard, remove the ECU and
check the wiring for continuity between main harness side
Disconnect the ECU and sensor connectors.
