P1093 INFINITI, NISSAN: VVEL ACTUATOR MOTOR BANK 2
The VVEL (Variable Valve Event & Lift) system controls the events and valve lift. The rotational movements of the drive shaft with an eccentric cam are transmitted to the output cam, using the rocker arm and two types of linkages to press the intake valve. The ECM (Engine Control Module) decides the valve lift according to the driving condition. Then, it sends a command signal to the VVEL Control Module, which controls the rotation by the actuator motor and changes the output cam movement by varying the linkage support point. This operation results in a continuous change of valve lift to improve both engine response and performance.
The OBDII fault code P1093 is set on Nissan and Infiniti vehicles when VVEL actuator engine performance deficiencies are detected. In this case, the code applies to the engine bank 2.
Reasons for setting the P1093 OBD2 diagnostic code:
