The automobile fault code P1EA5 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 cost of fixing the P1EA5 fault code will depend on the hourly rate charged by the auto repair shop.

The P1EA5 code refers to a fault in the HybridEV Battery Interface Control Module 4 5 V Reference Circuit. The drive motor battery contains 288 cells grouped into three sections.

Each section is made up of a different number of cells and cell groups. The battery energy control module monitors the voltage of the 96 cell groups and communicates with the hybridEV powertrain control module 2 for diagnostic trouble code information.

The drive motor battery high-voltage interface control module encodes the voltage reading and transmits it to the battery energy control module. All components related to the battery control system are serviceable.

What are the possible causes of the P1EA5 fault code in an automobile?

If you’re experiencing the P1EA5 fault code in your automobile, it could be due to a faulty Hybrid/EV Battery Interface Control Module, an open or shorted harness, or poor electrical connection. The engine light may turn on as a symptom. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

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

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Hybrid/EV Battery Interface Control Module, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Hybrid/EV Battery Interface Control Module harness is open or shorted, or if the Hybrid/EV Battery Interface Control Module circuit has a poor electrical connection.

What are the consequences of ignoring the P1EA5 fault code in an automobile?

Ignoring the P1EA5 fault code in an automobile, which indicates a faulty Hybrid/EV Battery Interface Control Module, can lead to serious consequences. The engine light will remain on, and the vehicle may experience reduced performance, decreased fuel efficiency, and potential damage to the battery. It is crucial to address the issue by visually inspecting the wiring harness and connectors, checking for damaged components, and fixing any poor electrical connections.
