PROCEDURE
1. | CHECK HARNESS AND CONNECTOR |
*a | Front view of wire harness connector (to Camshaft Position Sensor (for Intake Camshaft)) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the camshaft position sensor (for intake camshaft) connector.
(b) Turn the power switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
C51-3 (VC) - Body ground | Power switch on (IG) | 4.5 to 5.5 V |
C51-1 (VVI+) - Body ground | Power switch on (IG) | 3.0 to 5.0 V |
(d) Turn the power switch off and wait for at least 30 seconds.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
C51-3 (VC) - C51-1 (VVI+) | Power switch off | 1.425 to 1.575 kΩ |
C51-2 (VVI-) - Body ground | Always | Below 1 Ω |
NG | GO TO STEP 4 |
|
2. | CHECK SENSOR INSTALLATION AND CONDUCT VISUAL INSPECTION (CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT)) |
*a | Clearance |
(a) Visually check the camshaft position sensor (for intake camshaft) for damage.
(b) Check the camshaft position sensor (for intake camshaft) installation condition.
OK:
The camshaft position sensor (for intake camshaft) does not have any damage and is installed properly.
NG | SECURELY REINSTALL CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) |
|
3. | INSPECT INTAKE CAMSHAFT (TIMING ROTOR) |
(a) Check the timing rotor of the intake camshaft.
OK:
Camshaft timing rotor does not have any cracks or deformation.
HINT:
Perform "Inspection After Repair" after replacing the intake camshaft.

OK | REPLACE CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) |
NG | REPLACE INTAKE CAMSHAFT |
4. | CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) - ECM) |
(a) Disconnect the camshaft position sensor (for intake camshaft) connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
C51-1 (VVI+) - C88-90 (VV1+) | Always | Below 1 Ω |
C51-2 (VVI-) - C88-89 (VV1-) | Always | Below 1 Ω |
C51-3 (VC) - C88-88 (VCV1) | Always | Below 1 Ω |
C51-1 (VVI+) or C88-90 (VV1+) - Body ground and other terminals | Always | 10 kΩ or higher |
C51-2 (VVI-) or C88-89 (VV1-) - Body ground and other terminals | Always | 10 kΩ or higher |
C51-3 (VC) or C88-88 (VCV1) - Body ground and other terminals | Always | 10 kΩ or higher |
OK | REPLACE ECM |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
