TROUBLESHOOTING PROCEDURES





CIRCUIT DIAGRAM

HARNESS INSPECTION PROCEDURE











USING OSCILLOSCOPE





(1) Run the engine at an idle speed.
(2) Connect the probe to the oscilloscope pick-up point as shown in the circuit diagram, and check the waveform.

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.
