P1088 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 link support point. As a result, valve lift continuously changes to improve engine power and response.

P1089 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 link pivot point. As a result, valve lift continuously changes 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.

P1089 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 considerably 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 tumble generator sensor is responsible for measuring the position of the tumble generator throttle valves. When the throttle valves open or close, the signal voltage varies accordingly at the position sensor.
The diagnostic trouble code (DTC) is set when the ECM detects a high voltage signal from the tumble generator valve position sensor.
