DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P001400 | Camshaft Position "B" - Timing Over-Advanced or System Performance Bank 1 | Exhaust valve timing is stuck at a certain value when in the advance range (2 trip detection logic). |
| Comes on | DTC stored | SAE Code: P0014 |
P001500 | Camshaft Position "B" - Timing Over-Retarded Bank 1 | Exhaust valve timing is stuck at a certain value when in the retard range (1 trip detection logic). |
| Comes on | DTC stored | SAE Code: P0015 |
MONITOR DESCRIPTION
The ECM optimizes the exhaust valve timing using the Variable Valve Timing (VVT) system to control the exhaust camshaft. The VVT system includes the ECM, cam timing oil control solenoid assembly, camshaft timing oil control valve assembly and camshaft timing exhaust gear assembly. The ECM sends a target duty-cycle control signal to the cam timing oil control solenoid assembly. The camshaft timing oil control valve assembly is operated to control the oil pressure supplied to the camshaft timing exhaust gear assembly based on this signal. The camshaft timing gear assembly can advance or retard the exhaust camshaft.
If the difference between the target and actual exhaust valve timing is large, and changes in the actual exhaust valve timing are small, the ECM interprets this as the camshaft timing exhaust gear assembly stuck malfunction and stores a DTC.
These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to a camshaft timing oil control valve assembly malfunction or the presence of foreign matter in the camshaft timing oil control valve assembly.

TYPICAL MALFUNCTION THRESHOLDS
P0014: Advanced Camshaft Timing Both of the following conditions are met | - |
Deviation of actual valve timing and target valve timing | More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit |
Valve timing | No change at advanced valve timing |
Both of the following conditions are met | - |
Deviation of actual valve timing and target valve timing | More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit |
Valve timing | No change at retarded valve timing |
If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.
