SFI SYSTEM, Diagnostic DTC:P264A

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:

Position sensor output error

Angle sensor output error

(1 trip detection logic)

 Continuously variable valve lift controller assembly

CAUTION / NOTICE / HINT

Note

When the one of the following DTCs is stored and the MIL is illuminated, DTC P1047 is stored and actuator position learning is performed every time the engine is started. Also, after the system returns to normal, the following occurs during the first driving cycle: 1) DTC P1047 is stored, 2) actuator position learning is performed and 3) the MIL illuminates during actuator position learning.

Actuator position learning is performed when these DTCs are output.
P1046, P1049, P104A, P1055, P2646, P2647, P2648, P2649, P264A, U011B
