The automobile fault code p06b1 can be caused by a faulty StarterGenerator Control Module, an open or shorted harness, a poor electrical connection in the circuit, or a faulty Engine Control Module (ECM).

  • The fault code P06B1 can be caused by: a faulty Starter/Generator Control Module, an open or shorted harness in the Starter/Generator Control Module, a poor electrical connection in the Starter/Generator Control Module circuit, or a faulty Engine Control Module (ECM).

To fix the automobile fault code p06b1, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p06b1, 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 if there are any broken, bent, pushed out, or corroded pins in the connectors.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p06b1 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 p06b1 fault code.

The P06B1 fault code refers to the Sensor Supply Voltage Circuit having a low voltage. This fault is handled within the generator control module, which consists of the hybridEV powertrain control module 1, the 14 V power module, and the drive motor control module.

These control modules are non-serviceable and are part of the generator control module. The drive motor control module relies on a 15 V internal reference power supply to operate the drive motor sensors and processor. When the reference voltage drops below 8.8 V for 1 second, the Diagnostic Trouble Code (DTC) is set, indicating the low voltage issue in the Sensor Supply Voltage Circuit.

To resolve this fault code, it is necessary to diagnose and repair the generator control module, specifically addressing the low voltage issue in the Sensor Supply Voltage Circuit.

What are the possible causes for the automobile fault code p06b1?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P06B1 could be the culprit. This code is often caused by a faulty starter/generator control module, an open or shorted harness, a poor electrical connection in the control module circuit, or a faulty engine control module (ECM). 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. Don’t forget to check the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the fault code p06b1?

If you’re dealing with the fault code P06B1 and your engine light is on, it’s time to take action. The most common causes for this code are a faulty Starter/Generator Control Module or issues with the wiring harness and connectors. 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.
