The automobile fault code P1A4E 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 fixing cost of P1A4E will be between $75 and $150, depending on the repair time required.

The P1A4E code refers to a fault in the battery energy control module (BECM) of the drive motor generator. The BECM monitors the battery voltage and terminal voltage of the hybrid battery system. If the BECM detects a high voltage in the hybrid battery system, it will trigger the P1A4E fault code.

This fault code is communicated to the Hybrid Powertrain Control Module (HPCM) for diagnosis and troubleshooting. The P1A4E fault code indicates a potential issue with the hybrid battery system voltage and should be addressed promptly to avoid further damage.

What are the possible causes of the P1A4E automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A4E fault code. This code is caused by a faulty drive motor generator battery control module, an open or shorted harness, or poor electrical connection in the control module circuit. To fix this issue, you should visually inspect the 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 related wiring harness and connectors to fix the P1A4E fault code?

If you’re experiencing the P1A4E fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code is caused by a faulty Drive Motor Generator Battery Control Module, an open or shorted harness, or a poor electrical connection. To fix it, check the possible causes listed above and look for damaged components. Check for broken, bent, pushed out, or corroded connector’s pins to ensure that everything is in working order.
