P1091 Fault Code: Understanding The Fuel Trim System Malfunction
The P1091 fault code refers to the VVEL Actuator Motor Relay Circuit. The VVEL system controls valve event and lift continuously to improve engine output and response.
The Engine Control Module (ECM) sends a command signal to the VVEL control module, which controls the rotation of the control shaft using the VVEL actuator motor.
The VVEL actuator motor relay provides power supply to the VVEL control module. If the VVEL actuator motor relay cannot be controlled by the VVEL control module, the ECM takes over the control. The P1091 code indicates a problem with the VVEL actuator motor relay circuit.
