FUEL SYSTEM (DFI) 3-55

Camshaft Position Sensor (Service Code 23)

Start the engine and switch the diagnosis mode to Dealer 1 mode to know all the problem that the DFI system has at the time of self-diagnosis. If the engine cannot be started, the self-diagnosis system does not detect dynamic condition of the camshaft position sensor. In this case, turn off the ignition switch and turn it on again to enter the Dealer 2 mode. In this mode, the system tells all the troubles which the DFI system had in both static and dynamic conditions.

Camshaft Position Sensor Removal/Installation

The camshaft position sensor detects the position of the camshaft,• and distinguishes the cylinder.

See the Ignition system section in the Electric System chapter.

Camshaft Position Sensor Inspection

○The camshaft position sensor has no power source, and when the engine stops, the camshaft position sensor gen-

•erates no signal.

Crank the engine and measure the peak voltage of the camshaft position sensor (see Electrical System chapter)

•in order to check the sensor.

Check the wiring for continuity, using the following diagram.
