| DTC Code | DTC Name |
|---|---|
| P264A | "A" Rocker Arm Actuator Position Sensor Circuit Bank 1 |
DESCRIPTION
There are position sensor and angle sensor in the continuously variable valve lift controller assembly. They detect the actuator position and rotation direction. When there is a malfunction in any of the sensors, a DTC is stored and the MIL illuminates.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P264A | When either of the following conditions is met (1 trip detection logic):
|
Continuously variable valve lift controller assembly |
CAUTION / NOTICE / HINT
Note
When one of the following DTCs is output and the MIL is illuminated, actuator position learning is performed during the next trip. After the system returns to normal, actuator position learning is performed during the next trip and the MIL remains illuminated until learning is complete.
| Actuator position learning is performed when these DTCs are output. |
