Step 1
Initial Inspection
(a)
Check the sensor wiring harness connector EN15 whether
there is loose or poor connection and so on.
(b)
Check whether the sensor is installed correctly.
(c)
Check whether the sensor gap is normal.
Are above mentioned parts normal?
No
Repair the faulty part. Go to step 9
Yes
Step 2
Measure sensor 5 V reference voltage.

Camshaft Position Sensor Harness
Connector EO15
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect camshaft position sensor wiring harness
connector EN15.
(c)
Turn the ignition switch to "ON" position.
(d)
Measure voltage between camshaft position sensor wiring
harness connector EN15 terminal No.3 and a reliable ground.
Standard Voltage: 4.5-5 .5 V
(e)
Connect camshaft position sensor wiring harness connector
EN15.
Is the value specified value?
No
Yes
Step 3
Measure sensor signal circuit.
