If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1b0b fault code. Here are the symptoms to look out for:

  • The P1B0B fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, and other warning lights may illuminate on the dashboard.
  • The engine may run rough or stall, and there may be a decrease in power or acceleration.
  • The vehicle may also experience reduced fuel efficiency, and there may be a noticeable increase in emissions.
  • Additionally, the vehicle may fail to start or experience difficulty starting.
  • These symptoms can indicate a range of issues, including problems with the engine, transmission, or emissions system.

The P1B0B fault code can be caused by various issues related to the Drive Motor 1 Control Module HybridEV Battery.

  • The automobile fault code P1B0B can be caused by a faulty Drive Motor 1 Control Module Hybrid/EV Battery.
  • It can also be caused by an open or shorted Drive Motor 1 Control Module Hybrid/EV Battery harness.
  • Additionally, a poor electrical connection in the Drive Motor 1 Control Module Hybrid/EV Battery circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1b0b, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1b0b, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1B0B has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the total cost of fixing the P1B0B fault code will depend on the hourly rate charged by the repair shop and the estimated repair time.

The P1B0B fault code relates to the power inverter module in hybrid vehicles. It contains two motor control modules that measure hybrid battery high voltage. Loss of isolation between high-voltage circuits and vehicle chassis is tested when high-voltage contactor relays are closed.

Motor control module loss of isolation is detected through two high-impedance resistors and voltage measuring circuitry. The motor isolation voltage display will indicate voltage that is more or less than actual hybrid battery high voltage when a loss of isolation is present.

The motor control module monitors the loss of isolation voltage measuring circuitry for correct operation.

What are the possible causes of the P1B0B fault code in an automobile?

If you’re experiencing the P1B0B fault code in your automobile, it could be due to a faulty Drive Motor 1 Control Module Hybrid/EV Battery, an open or shorted Drive Motor 1 Control Module Hybrid/EV Battery harness, or a poor electrical connection in the Drive Motor 1 Control Module Hybrid/EV Battery circuit. To fix the issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the wiring harness and connectors related to the Drive Motor 1 Control Module Hybrid/EV Battery?
