The P1090 fault code refers to the VVEL Actuator Motor Bank.

This code indicates a problem with the actuator motor that controls the Variable Valve Event & Lift (VVEL) system in the engine. The VVEL system is responsible for continuously adjusting the valve event and lift to optimize engine performance.

The VVEL system works by transmitting the rotational movement of the drive shaft to the output cam through various components, including the rocker arm and links. The Engine Control Module (ECM) determines the desired valve lift based on the driving conditions and sends a command signal to the VVEL control module.

The VVEL control module then uses the actuator motor to control the rotation of the control shaft, which in turn shifts the link supporting point and changes the movement of the output cam.

This continuous adjustment of the valve lift helps improve engine output and response.

If the P1090 fault code is triggered, it means there is an issue with the VVEL actuator motor in one of the banks of the engine. This could be due to a malfunctioning motor, wiring problem, or other related component failure. It is important to diagnose and fix this issue promptly to ensure optimal engine performance.

What are the possible causes of the automobile fault code P1090?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1090 could be the culprit. This code is often caused by a faulty VVEL actuator motor, an open or shorted VVEL actuator motor harness, poor electrical connections in the VVEL actuator motor circuit, a faulty VVEL actuator sub assembly, a faulty VVEL ladder assembly, or a faulty VVEL control module. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the P1090 fault code?

If you’re dealing with the P1090 fault code and notice that your engine light is on, it’s time to take action. The most common cause of this issue is a faulty VVEL Actuator Motor, but it could also be due to an open or shorted harness, poor electrical connection, or problems with the VVEL control module. To fix this, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or corroded pins. This simple step could be the key to resolving the problem and getting your engine back in top shape.

What should I look for when checking for damaged components and connector’s pins to resolve the P1090 fault code?

If you’re dealing with the P1090 fault code and your engine light is on, it’s important to check for damaged components and connector’s pins. This fault code can be caused by a faulty VVEL Actuator Motor, an open or shorted VVEL Actuator Motor harness, poor electrical connection in the VVEL Actuator Motor circuit, a faulty VVEL actuator sub assembly, a faulty VVEL ladder assembly, or a faulty VVEL control module. To resolve the issue, visually inspect the related wiring harness and connectors, and be on the lookout for broken, bent, pushed out, or corroded connector’s pins.
