To fix the p1091 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1091, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins on the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p1091 are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p1091 fault code.

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.

What are the possible causes of the automobile fault code P1091 and how can I visually inspect them?

If you’re seeing the engine light or service engine soon warning light and have the fault code P1091, there are a few possible causes to consider. It could be a faulty VVEL actuator motor relay, an open or shorted harness, a poor electrical connection in the relay circuit, or even a faulty VVEL control module or engine control module (ECM). To visually inspect these potential issues, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to also check the components for any signs of damage.

How can a faulty VVEL Actuator Motor Relay or a poor electrical connection in the VVEL Actuator Motor Relay circuit trigger the P1091 fault code?

If you notice the Engine Light or Service Engine Soon Warning Light illuminated, it could be due to a faulty VVEL Actuator Motor Relay or a poor electrical connection in the VVEL Actuator Motor Relay circuit. This can trigger the P1091 fault code. To fix this issue, you should visually inspect the wiring harness and connectors related to the VVEL Actuator Motor Relay. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. It’s important to address these possible causes to resolve the problem.

What steps should I take to fix the P1091 fault code and ensure that the related wiring harness and connectors are in good condition?

To fix the P1091 fault code and ensure the wiring harness and connectors are in good condition, follow these steps. First, check the possible causes mentioned above. Then, visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This will help identify any issues and ensure the wiring harness and connectors are in proper working order.

p1091 error fault code explained

If your engine light is on and you’re getting the P1091 fault code, it could be due to a faulty VVEL Actuator Motor Relay, an open or shorted harness, poor electrical connection, or a faulty VVEL Control Module or Engine Control Module (ECM). To fix it, visually inspect the wiring harness and connectors for any damage, and check for broken, bent, pushed out, or corroded pins on the connectors.
