DTC P0014 Camshaft Position "B" - Timing Over-Advanced or System Performance (Bank 1)
DTC P0015 Camshaft Position "B" - Timing Over-Retarded (Bank 1)
DTC P0024 Camshaft Position "B" - Timing Over-Advanced or System Performance (Bank 2)
DTC P0025 Camshaft Position "B" - Timing Over-Retarded (Bank 2)
HINT: If DTC P0014, P0015, P0024 or P0025 is present, check the VVT (Variable Valve Timing) system.

MONITOR DESCRIPTION
DTC P0014 and P0024
The ECM compares current valve timing with target valve timing, while the engine
is running and after
being warmed up, in order to monitor the VVT system on the exhaust side. Valve
timing is calculated from
the positions of the camshaft and crankshaft. The ECM controls the engine so
that current valve timing
meets target valve timing. If these timings are not met, the ECM determines this
as a malfunction.

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
Advanced camshaft timing:
Retarded camshaft timing:
If the difference between the target and actual camshaft timings is greater than the specified value, the ECM operates the VVT actuator.
Then, the ECM monitors the camshaft timing change for 5 seconds.

INSPECTION PROCEDURE
HINT:
1 CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0014, P0015, P0024 OR P0025)
Result
HINT: If any DTCs other than P0014, P0015, P0024 or P0025 are output, troubleshoot those DTCs first.
2 PERFORM ACTIVE TEST BY INTELLIGENT TESTER (OPERATE OCV)
OK
3 CHECK WHETHER DTC OUTPUT RECURS (DTC P0014, P0015, P0024 OR P0025)
OK: No DTC output
SYSTEM IS OK
4 CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP TEETH ON TIMING CHAIN)
OK: The matchmarks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.
5 INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (OCV)
Standard resistance
OK: Valve moves quickly.
6 CHECK OIL PIPE AND OIL CONTROL VALVE FILTER
OK: The filter and pipe are not clogged
7 REPLACE CAMSHAFT TIMING GEAR ASSEMBLY
8 CHECK WHETHER DTC OUTPUT RECURS
OK: No DTC output.
HINT: DTC P0014, P0015, P0024 or P0025 is output when foreign objects in engine oil are caught in some parts of the system. These codes will stay registered even if the system returns to normal after a short time. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
SYSTEM IS OK

Data list / active test
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
actuator and other item values to be read without
removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
Connect the intelligent tester with CAN VIM to the
DLC3.

Place the seat assembly in the cabin.
NOTICE:
Be careful not to damage the body.
Connect the connectors under the seat assembly.
Tighten the 2 bolts on the front side of the seat
assembly.
