Component Tests and General Diagnostics

Testing of the Camshaft Position Sensor
Testing of the sensor involves testing of the harness. If the harness tests properly and there is an abnormality in the camshaft position sensor system, then the sensor should be replaced. For Testing Procedures, see the Diagnostic Charts for trouble code 23 - Camshaft Position Sensor.

TROUBLESHOOTING HINTS
Hint 1: If the camshaft position sensor does not function correctly, correct sequential injection is not being carried out, so that the engine may stall, run irregularly at idle or fail to accelerate normally.

Hint 2: If the sensor outputs a pulse signal when the ignition switch is turned ON (without starting the engine) , the cause is probably a malfunction of the camshaft position sensor or engine control module.
