DESCRIPTION
Refer to DTC P0013 (See page ).
DTC No. |
DTC Detection Condition |
Trouble Area |
---|---|---|
P0014 |
The valve timing is stuck at a certain value when in the advance range (2 trip detection logic). |
|
P0015 |
The valve timing is stuck at a certain value when in the retard range (1 trip detection logic). |
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, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing exhaust gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller 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 a VVT controller stuck malfunction and stores a DTC.
