P1Ea4: Your Car’s Oxygen Sensor Needs Attention
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.
FAQ
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.
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.
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.
