HINT:
If DTC P0014, P0015, P0024 or P0025 is present, check the VVT (Variable Valve Timing) system.
DESCRIPTION
Refer to DTC P0013 (See page ES-87).
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.
DTC P0015 and P0025
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.
MONITOR STRATEGY
TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
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)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
(d) Read the DTCs.
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)
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine and turn the tester on.
(c) Warm up the engine.
(d) Select the following menu items on the tester: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / VVT EX B1 or VVT EX B2.
(e) Check the engine speed while operating the Oil Control Valve (OCV) using the tester.
OK
3 CHECK WHETHER DTC OUTPUT RECURS (DTC P0014, P0015, P0024 OR P0025)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Clear the DTCs (See page ES-39).
(d) Start the engine and warm it up.
(e) Select the check mode using the tester (See page ES- 43).
(f) Drive the vehicle for more than 10 minutes.
(g) Read the DTCs using the tester.
OK: No DTC output.
SYSTEM IS OK
4 CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP TEETH ON TIMING CHAIN)
(a) Remove the cylinder head covers RH and LH.
(b) Turn the crankshaft to align the matchmarks of the crankshaft.
(c) Align the notch of the crankshaft pulley to the "0" position.
(d) Check if the matchmarks of the camshaft pulley and camshaft bearing cap align.
(e) Turn the crankshaft clockwise by 360° if the matchmarks do not align. Check if they align once again.
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)
(a) Remove the OCV.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Apply positive battery voltage to terminal 1 and negative battery voltage to terminal 2. Check the valve operation.
OK: Valve moves quickly.
(d) Reinstall the OCV.
6 CHECK OIL PIPE AND OIL CONTROL VALVE FILTER
(a) Remove the oil pipe No. 1 or oil pipe assembly.
(b) Remove the oil control valve filter.
(c) Check that the filter and pipe are not clogged.
OK: The filter and pipe are not clogged.
7 REPLACE CAMSHAFT TIMING GEAR ASSEMBLY
8 CHECK WHETHER DTC OUTPUT RECURS
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Clear the DTCs (See page ES-39).
(d) Start the engine and warm it up.
(e) Select the check mode using the tester (See page ES- 43).
(f) Drive the vehicle for more than 10 minutes.
(g) Confirm that no DTC is set using the tester.
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.
