CAMSHAFT POSITION SENSOR <From 1993 models>
Camshaft position sensor
Engine control module connector
OPERATION
The camshaft position sensor senses the top dead center on compression stroke, converts it into
l
a pulse signal and inputs it to the engine control module, which then controls the fuel injection sequence,
etc. based on the input signal.
Power to the camshaft position sensor is supplied from the MFI relay and is grounded to the body.
l
The camshaft position sensor generates a pulse signal as it repeatedly connects and disconnects
between 5 V voltage supplied from the engine control module and ground.
TROUBLESHOOTING HINTS
Hint 1: If the camshaft position sensor does not function correctly, correct sequential injection is not
made 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 (with the engine not
running), a faulty camshaft position sensor or engine control module is suspected.
Refer to P.l3A-104.
