The automobile fault code P105B indicates that the engine light is on or the service engine soon warning light is illuminated. This fault code can be caused by various factors, including a low battery voltage, a faulty control module variable valve timing (VVT), an open or shorted VVT harness, or a poor electrical connection in the VVT circuit. To fix this issue, it is recommended to visually inspect the wiring harness and connectors related to the VVT system.

Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

The repair time for this issue is estimated to be around 1.0 hour.

It is important to address this fault code promptly to prevent any further damage to the vehicle.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p105b fault code.

  • The symptoms of the automobile fault code p105b include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p105b can be caused by a low battery voltage, faulty Control Module Variable Valve Timing (VVT), an open or shorted Control Module VVT harness, or a poor electrical connection in the Control Module VVT circuit.

  • The fault code p105b can be caused by the following: – Battery voltage too low.
  • – Faulty Control Module Variable Valve Timing (VVT).
  • – Control Module VVT harness is open or shorted.
  • – Control Module VVT circuit poor electrical connection.

To fix the automobile fault code p105b, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p105b, 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 pins on the connectors.
  • This fix typically takes around 1.0 hour to complete.

The automobile fault code P105B diagnosis and fixing cost is influenced by the estimated repair time of 1.0 hour. Most auto repair shops typically charge between $75 and $150 per hour for their services.

The P105B fault code refers to an Internal Control Module VVT Error Voltage Too Low.

This code is related to the Valvetronic VVT system, which helps reduce fuel consumption by adjusting the stroke of the intake valves.

The system uses an electric motor to drive a worm gear that moves the eccentric shaft. Intermediate levers are used to change the effect of the camshaft on the rocker arms. When the high side or low side transistors detect an excess current, the Diagnostic Trouble Code (DTC) is set.

In the case of P105B, the error voltage is too low, indicating a problem with the control module’s internal voltage.

What are the possible causes of the automobile fault code p105b?

If you see the engine light or service engine soon warning light on, the fault code P105B might be the culprit. This code can be caused by a few things, including a low battery voltage, a faulty control module variable valve timing (VVT), an open or shorted VVT harness, or a poor electrical connection in the VVT circuit. To fix this issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, inspect for any damage, and check for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the p105b fault code?

If you’re dealing with the p105b fault code and your engine light is on, it’s time to take action. The cause could be a low battery voltage, a faulty Control Module Variable Valve Timing (VVT), an open or shorted Control Module VVT harness, or a poor electrical connection in the Control Module VVT circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors. Don’t delay, get to the bottom of this problem now!

What should I look for when checking for damaged components or corroded connector pins to resolve the p105b fault code?

When resolving the p105b fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By doing so, you can identify any issues that may be causing the fault code and take the necessary steps to fix them.

p105b error fault code explained

If your engine light is on and you’re dealing with a P105B fault code, it could be due to a few reasons. The battery voltage might be too low, or there could be an issue with the Control Module Variable Valve Timing (VVT).

It’s also possible that the Control Module VVT harness is open or shorted, or there’s a poor electrical connection in the Control Module VVT circuit.

To fix this, start by visually inspecting the wiring harness and connectors.

Look for any damaged components and check if any connector pins are broken, bent, pushed out, or corroded.
