P1090 NISSAN Meaning

VVEL (Variable Valve Event & Lift) is a system that continuously controls valve event and valve lift. The rotational movement of the drive shaft equipped with an eccentric cam is transmitted to the output cam via the rocker arm and two types of links to push the intake valve. The engine control module (ECM) determines the target valve lift based on driving conditions and sends the control signal to the VVEL control module. The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor and changes the output cam movement by shifting the linkage pivot point. As a result, valve lift continuously changes to improve engine power and response.

P1090 SUBARU Meaning

The tumble generator system uses an electronically controlled throttle valve in each intake port.
During cold idle, the tumble generator system will redirect the air charge through another port. These ports have a finishing characteristic that causes the air/fuel mixture to swirl and tumble significantly and creates better combustion. This results in better idle quality, cleaner emissions, and easier cold starts.
Once the vehicle is warmed up, the tumble generator system will be disabled and the intake air charge will be directed through the standard intake ports.
The diagnostic trouble code (DTC) sets when the tumble generator valve is detected open when the desired position is closed.

P1091 Possible Causes

Power to the VVEL actuator motor is supplied to the VVEL control module through the VVEL actuator motor relay. The VVEL actuator motor relay is controlled ON/OFF by the VVEL control module. Additionally, when the VVEL actuator motor relay cannot be controlled by the VVEL control module for any reason, it is controlled ON/OFF by the ECM.

P1092 Meaning

VVEL (Variable Valve Event & Lift) is a system that continuously controls valve event and valve lift. The rotational movement of the drive shaft equipped with an eccentric cam is transmitted to the output cam via the rocker arm and two types of links to push the intake valve. The engine control module (ECM) decides the target valve lift based on driving conditions and sends the control signal to the VVEL control module. The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor and changes the output cam movement by shifting the linkage pivot point. As a result, valve lift changes continuously to improve engine power and response.
The VVEL control shaft position sensor (1) is placed on the VVEL actuator sub-assembly and detects the position angle of the control shaft. A magnet is pressed into the arm on the edge of the control shaft.
The magnetic field changes when the magnet rotates with the arm, resulting in a change in the sensor’s output voltage. The VVEL control module detects the actual position angle through the voltage change and sends the signal to the ECM.
