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 condi-
tion 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.

•
Crank the engine and measure the peak voltage of the
camshaft position sensor (see Electrical System chapter)
in order to check the sensor.
