Camshaft Position Sensor: Component Tests and General Diagnostics
Component Testing
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.
Harness Inspection
STEP 1. Check for continuity between the camshaft position sensor and the MFI relay.
-
MFI relay connector: Disconnected
-
Camshaft position sensor connector: Disconnected
-
Insert the probes of the circuit tester into both ends of the harness.
OK: GO TO STEP 2
NG: Repair the harness. (A3 - B1)
STEP 2. Check for continuity in the ground circuit.
-
Camshaft position sensor connector: Disconnected
OK: GO TO STEP 3
NG: Repair the harness. (A1 - Ground)
STEP 3. Check for an open circuit or a short-circuit to ground between the camshaft position sensor and engine control module.
-
Engine control module connector: Disconnected
-
Camshaft position sensor connector: Disconnected
OK: GO TO STEP 4
NG: Repair the harness. (A2 - 50)
