If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p1fed fault code. Here are the symptoms to look out for:

  • The P1FED fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, poor acceleration, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting or fail to start altogether.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1FED fault code can be caused by issues with the HybridEV Battery Interface Control Module and its connections.

  • The automobile fault code P1FED can be caused by a faulty Hybrid/EV Battery Interface Control Module.
  • It can also be caused by an open or shorted Hybrid/EV Battery Interface Control Module harness.
  • Additionally, a poor electrical connection in the Hybrid/EV Battery Interface Control Module circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p1fed, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1fed, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1FED 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 P1FED will be between $75 and $150, depending on the repair time required.

The P1FED code is related to the HybridEV Battery Interface Control Module 5 Voltage Sensor Performance. The hybrid battery contains 192 individual cells, which are electrically connected in series.

The battery energy control module monitors the voltage of the 96 battery cell groups. The battery energy control module contains internal interface control modules that monitor specific cell groups. The hybrid powertrain control module 2 is the host controller for diagnostic trouble code information.

The battery energy control module communicates diagnostics and system status to the hybrid powertrain control module 2 through serial data.

What are the possible causes of the P1FED fault code in an automobile?

If you’re experiencing the P1FED fault code in your automobile, it’s likely that your engine light is on. This could be due to a faulty Hybrid/EV Battery Interface Control Module, an open or shorted harness, or a poor electrical connection in the module circuit. To fix the issue, it’s recommended to 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 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 steps to take when checking for damaged components and broken, bent, pushed out, or corroded connector’s pins in an automobile with the P1FED fault code?

If you encounter the P1FED fault code in your automobile, with the engine light ON or Service Engine Soon Warning Light, you should check for a faulty Hybrid/EV Battery Interface Control Module, an open or shorted Hybrid/EV Battery Interface Control Module harness, or a poor electrical connection in the Hybrid/EV Battery Interface Control Module circuit. To fix this issue, visually inspect the related wiring harness and connectors, and check for damaged components, broken, bent, pushed out, or corroded connector’s pins.
