If you notice the engine light on or service engine soon warning light, it could be due to the p1ea4 fault code. Here are some symptoms to look out for:

  • The P1EA4 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms 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.

P1EA4 fault code can be caused by issues with the HybridEV Battery Interface Control Module or its circuit connections.

  • The automobile fault code P1EA4 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 p1ea4 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p1ea4, you need to check the possible causes listed above.
  • 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 fault code P1EA4 indicates an issue with the hybrid battery pack coolant pump. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

It is important to address this issue promptly to avoid further damage to the hybrid battery pack.

The P1EA4 code is related to the HybridEV Battery Interface Control Module 4 Cell Balancing Circuit. The hybridEV powertrain control module 2 uses cell balancing to maintain a similar state of charge on the cell groups. 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 are used for cell balancing.

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.

What are the possible causes of the P1EA4 fault code in an automobile?

If you’re experiencing the P1EA4 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 poor electrical connection in the module circuit. To fix the issue, it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent 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 P1EA4 fault code in an automobile?

Ignoring the P1EA4 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, it is important to visually inspect the wiring harness and connectors, and check for damaged components. Ignoring this fault code can lead to further damage to the vehicle and potentially costly repairs.
