[SOLVED] P1A2E Code: How To Fix Low Voltage In Hybrid Battery 2

If you see the engine light on or the service engine soon warning light, it could be due to the P1A2E fault code.

This code indicates a problem with the Energy Storage Box (ESB) battery or the Battery Energy Control Module (BECM). The cause could be a faulty BECM, an open or shorted BECM harness, or poor electrical connection in the BECM circuit.

It is important to address this issue promptly as it can affect the performance of your vehicle. The repair time for this fault code is estimated to be around 1.0 hour.

To fix the issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a2e fault code. Here are the symptoms to look out for:

  • The P1A2E 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, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience a decrease in acceleration and overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1A2E fault code can be caused by a faulty ESB battery, BECM module, harness, or poor electrical connection.

  • The automobile fault code P1A2E can be caused by a faulty Energy Storage Box (ESB) Battery.
  • It can also be caused by a faulty Battery Energy Control Module (BECM).
  • Another cause of this fault code is when the Battery Energy Control Module (BECM) harness is open or shorted.
  • Lastly, a poor electrical connection in the Battery Energy Control Module (BECM) circuit can also cause this fault code.

To fix the p1a2e automobile fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1a2e, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 is P1A2E. The estimated repair time is 1.0 hour.

The cost of fixing the fault code is based on the repair time. Auto repair shops usually charge between $75 and $150 per hour.

These factors are influential in determining the overall cost of diagnosing and fixing the automobile fault code.

The P1A2E code is related to the hybrid battery voltage. It indicates that the voltage of the second battery in the Energy Storage Box is very low.

The Energy Storage Control Module (ESCM) uses battery voltage sensors to monitor the voltage of the batteries. The ESCM monitors the voltage drop across the battery voltage sensors and uses the inputs for hybrid calculations.

When the battery voltage is low, the resistances of the sensors are low and the voltage signals are low. This fault code can cause issues with the hybrid system and should be addressed promptly.

What are the possible causes of the P1A2E fault code in an automobile?

If you’re experiencing the P1A2E fault code in your automobile, you may notice that the engine light is on or the service engine soon warning light is illuminated. This fault code is typically caused by a faulty Energy Storage Box (ESB) battery, a faulty Battery Energy Control Module (BECM), an open or shorted BECM harness, or a poor electrical connection in the BECM circuit. To fix the issue, it’s recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
