[SOLVED] P107A Code: Variable Valve Lift Power Stage Warning – How To Fix It!

The automobile fault code P107A indicates a problem with the Variable Valve Timing (VVT) Servo Motor. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty VVT Servo Motor, an open or shorted harness, or a poor electrical connection in the VVT Servo Motor circuit. To fix this issue, you should visually inspect the wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this problem promptly to prevent further damage to the engine.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p107a fault code.

  • The symptoms of the automobile fault code p107a include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p107a can be caused by a faulty Variable Valve Timing (VVT) Servo Motor, an open or shorted Variable Valve Timing Servo Motor harness, or a poor electrical connection in the Variable Valve Timing Servo Motor circuit.

  • The fault code P107A can be caused by a faulty Variable Valve Timing (VVT) Servo Motor.
  • It can also be caused by an open or shorted Variable Valve Timing Servo Motor harness.
  • Additionally, a poor electrical connection in the Variable Valve Timing Servo Motor circuit can also trigger this fault code.

To fix fault code p107a, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p107a, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The automobile fault code p107a diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour.

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

The P107A fault code refers to a warning related to the Variable Valve Lift Power Stage. This code is associated with the Valvetronic VVT system, which helps reduce fuel consumption by adjusting the stroke of the intake valves. In the Valvetronic system, an electric motor drives a worm gear that moves the eccentric shaft.

The eccentric shaft, in turn, uses intermediate levers to change the effect of the camshaft on the rocker arms. The P107A code is triggered when the engine management system detects an electrical overload in the Variable Valve Timing (VVT) motor. If the current draw exceeds a defined threshold for several seconds, the VVT system is deactivated, and the engine switches to throttled operation.

This warning indicates a potential issue with the power stage of the Variable Valve Lift system.

What are the possible causes of the automobile fault code p107a?

If you see the engine light or service engine soon warning light on, the fault code P107A could be the culprit. This code is often caused by a faulty Variable Valve Timing (VVT) Servo Motor or issues with the wiring harness and connectors. To fix the problem, visually inspect the wiring harness and connectors for any damage. Check for broken, bent, pushed out, or corroded pins on the connectors. It’s also a good idea to check the “Possible Causes” listed above for further troubleshooting.

How can I visually inspect the wiring harness and connectors to fix the p107a fault code?

If you’re dealing with the p107a fault code and your engine light is on, it’s time to take action. The most common causes of this code are a faulty Variable Valve Timing (VVT) Servo Motor, an open or shorted VVT Servo Motor harness, or a poor electrical connection in the VVT Servo Motor circuit. To fix it, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. Don’t forget to check the “Possible Causes” listed above for further troubleshooting.

What should I look for when checking for damaged components and connector’s pins to resolve the p107a fault code?

When resolving the p107a fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing so, you can identify any issues with the Variable Valve Timing (VVT) Servo Motor or its circuit connections. This step is crucial in troubleshooting the cause of the fault code and ensuring a proper fix.
