When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p106b fault code.

  • The symptoms of the automobile fault code P106B include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p106b can be caused by issues with the canister pressure sensor, manifold absolute pressure sensor, and their respective circuits.

  • The fault code P106B can be caused by the following: a faulty canister pressure sensor (canister assembly), a faulty manifold absolute pressure sensor, a faulty canister pressure sensor, an open or shorted canister pressure sensor harness, or a poor electrical connection in the canister pressure sensor circuit.

To fix the p106b fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P106B, 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 factors influencing the cost of diagnosing and fixing the automobile fault code p106b include the estimated repair time of 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services. These factors play a significant role in determining the overall cost of addressing the fault code.

The P106B fault code is specifically designed to identify any irregularities in the output characteristics of a pressure sensor in your automobile.

This code focuses on monitoring the pressure of both the canister pressure sensor and the manifold absolute pressure sensor approximately 55 minutes after the power switch has been turned off. If there is a noticeable difference in the pressures between these sensors, the Malfunction Indicator Lamp (MIL) will be illuminated. It is important to note that this fault code operates on a 2 trip detection logic, meaning that the issue must be detected on two separate occasions before the MIL is activated.

The P106B code specifically relates to the correlation between the Evaporative Emission System Pressure Sensor and the Secondary Air Injection Pressure Sensor.

What are the possible causes for the automobile fault code P106B?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P106B could be the culprit. This code is often caused by issues with the canister pressure sensor or the manifold absolute pressure sensor. It could be a faulty sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix it, start by visually inspecting the wiring harness and connectors. Look for any damage or signs of corrosion. Also, 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 P106B fault code?

To fix the P106B fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the issue lies with the canister pressure sensor or its circuit. Don’t forget to also check the other possible causes listed above.

What should I look for when checking for damaged components or corroded connector pins to resolve the P106B fault code?

When resolving the P106B 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 on the connectors. By doing so, you can identify any issues with the canister pressure sensor or its circuit, the manifold absolute pressure sensor, or the electrical connection. Take the necessary steps to repair or replace any damaged components or pins to resolve the issue.
