The fault code P1FDE is a common issue in automobiles. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop.

The cost may also vary based on the severity of the issue and the type of repair required. It is important to get this fault code fixed as soon as possible to avoid any further damage to the vehicle.

The P1FDE 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 P1FDE code indicates a fault condition in the HybridEV Battery Interface Control Module 10 Voltage Sensor Circuit, specifically a low voltage. The hybrid powertrain control module 2 is the host controller for diagnostic trouble code information.

What are the possible causes of the P1FDE fault code?

If you’re experiencing the P1FDE 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, check the possible causes listed above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded 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 P1FDE fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P1FDE fault code, you should visually inspect the related wiring harness and connectors. This will help you identify the cause of the problem and determine the appropriate fix. Checking for damaged components and looking for broken, bent, pushed out, or corroded connector’s pins is an important step in the process, as it can help you identify any issues that may be contributing to the fault code.
