If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1e99 fault code.

Here are the symptoms to look out for:

  • The P1E99 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, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1E99 fault code can be caused by issues with the HybridEV Battery Interface Control Module and its connections.

  • The automobile fault code P1E99 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 p1e99 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P1E99, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 P1E99 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P1E99 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P1E99 code is related to the HybridEV Battery Interface Control Module 2 5 V Reference Circuit.

The drive motor battery contains 288 cells grouped in parallel and series. The battery energy control module monitors the voltage of the 96 cell groups.

The drive motor battery high-voltage interface control module encodes the voltage reading and transmits it to the battery energy control module.

The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2 through serial data.

What are the possible causes of the P1E99 fault code in an automobile?

If you’re experiencing the P1E99 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 consequences of ignoring the P1E99 fault code in an automobile?

Ignoring the P1E99 fault code in an automobile can lead to serious consequences. The engine light will remain on, indicating a problem with the Hybrid/EV Battery Interface Control Module. This fault code is caused by a faulty module, open or shorted harness, or poor electrical connection. To fix the issue, one must visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. Ignoring this fault code can lead to further damage to the vehicle’s electrical system and potentially cause a breakdown.
