The P1FE7 code is related to the hybrid battery in a vehicle. The battery contains 192 individual cells, which are electrically connected in series. There are three distinct sections of the battery, each containing a different number of cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups.

The P1FE7 code indicates a fault condition in the HybridEV Battery Interface Control Module 9 Voltage Sensor Circuit, specifically a high voltage reading. This information is communicated to the hybrid powertrain control module 2 for diagnostic trouble code information.

What are the possible causes of the P1FE7 fault code?

If you’re experiencing the P1FE7 fault code, your engine light may be on. This could be due to a faulty Hybrid/EV Battery Interface Control Module, an open or shorted harness, or poor electrical connection in the circuit. To fix the issue, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins.

How can I 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 should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P1FE7 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P1FE7 fault code, you should replace or repair them as necessary. This will help ensure that the Hybrid/EV Battery Interface Control Module circuit has a good electrical connection and that the related wiring harness and connectors are functioning properly. Remember to check the “Possible Causes” listed above and visually inspect the related wiring harness and connectors.
