If you notice the Engine Light ON, it could be a sign of p1e9e fault code. Here are the symptoms to look out for:

  • The P1E9E fault code in automobiles 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, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1E9E fault code can be caused by a faulty control module, open or shorted harness, or poor electrical connection.

  • The automobile fault code P1E9E 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.

To fix the automobile fault code p1e9e, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1e9e, 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 P1E9E 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 P1E9E will depend on the hourly rate charged by the repair shop. It is important to consider these factors when estimating the cost of fixing this fault code.

The P1E9E code is related to the HybridEV Battery Interface Control Module 3 Cell Balancing Circuit. The powertrain control module 2 maintains a similar state of charge on the cell groups by removing energy from the cell groups that need it. Cell balancing is achieved through a resistor wired in parallel with the cell group and a transistor switch in series with the resistor internal to the hybridEV battery interface control module.

The hybridEV powertrain control module 2 sends a command to the hybridEV battery energy control module to begin cell balancing through the hybridEV battery interface control modules.
