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 gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) 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 gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) is operated to control the oil pressure supplied to the camshaft timing exhaust gear assembly based on this signal. The camshaft timing exhaust 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.
DTC P001400 and P002400 (Advanced Camshaft Timing) is subject to 2 trip detection logic.
DTC P001500 and P002500 (Retarded Camshaft Timing) is subject to 1 trip detection logic.
These DTCs indicate that the camshaft timing exhaust gear assembly cannot operate properly due to a camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) malfunction or the presence of foreign matter in the camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]).

P0014 and P0024: 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. |

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.
