When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0bc3 fault code.

  • The symptoms of the automobile fault code p0bc3 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p0bc3 can be caused by a faulty HybridEV Battery Assembly, an open or shorted HybridEV Battery Assembly harness, a poor electrical connection in the HybridEV Battery Assembly circuit, or a faulty HybridEV Battery Interface Control Module.

  • The fault code P0BC3 can be caused by a faulty Hybrid/EV Battery Assembly, an open or shorted Hybrid/EV Battery Assembly harness, a poor electrical connection in the Hybrid/EV Battery Assembly circuit, or a faulty Hybrid/EV Battery Interface Control Module.

To fix the automobile fault code p0bc3, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0bc3, 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 is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0bc3 based on the estimated repair time of 1.0 hour include the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P0BC3 fault code refers to a problem with the HybridEV Battery Temperature Sensor 5. This sensor is responsible for monitoring the temperature of the battery in hybrid or electric vehicles. It is located within the battery sections and there are two temperature sensors in each section.

The sensor works by measuring the resistance of the battery cell group, which changes with temperature. As the temperature decreases, the sensor resistance increases, and as the temperature increases, the sensor resistance decreases. The HybridEV Interface Control Module supplies 5V to the signal circuit and acts as a ground for the low reference circuit.

It communicates the temperature sensor values to the HybridEV Powertrain Control Module via serial data.

The Powertrain Control Module uses the battery temperature sensors to determine the overall battery module temperature and control the operation of the battery cooling system.

The P0BC3 fault code is triggered when the difference between one battery temperature sensor and the average of the other sensors is greater than 25°C (45°F).

This indicates a problem with the HybridEV Battery Temperature Sensor 5 and should be addressed to ensure proper functioning of the battery and cooling system.

What are the possible causes for the automobile fault code p0bc3?

If you see the engine light or service engine soon warning light on, the fault code P0BC3 could be the culprit. This code is often caused by a faulty Hybrid/EV Battery Assembly, an open or shorted harness, a poor electrical connection in the Hybrid/EV Battery Assembly circuit, or a faulty Hybrid/EV Battery Interface Control Module. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to consider the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the fault code p0bc3?
