The P1A29 fault code in automobiles indicates a problem with the Energy Storage Box (ESB) Battery or the Battery Energy Control Module (BECM). The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this issue could be a faulty ESB battery, BECM, or a poor electrical connection in the BECM circuit. The repair importance is high as it affects the performance of the vehicle. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors for any damage or corrosion.

The fault code can be interpreted using an OBD-II scanner.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a29 fault code.

Here are the symptoms to look out for:

  • The P1A29 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 P1A29 fault code can be caused by a faulty ESB battery, BECM module, harness, or poor electrical connection.

  • The automobile fault code P1A29 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.

Below are the possible fixes for the automobile fault code p1a29, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1A29, 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 fault code is P1A29. The estimated repair time is 1.0 hour.

The cost of fixing the fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour.

Therefore, the fixing cost of the P1A29 fault code will be between $75 and $150.

The P1A29 code is related to the Hybrid Battery 2 Circuit Low Voltage.

Battery voltage sensors are used to monitor the voltage of the batteries in the Energy Storage Box (ESB). 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, triggering the P1A29 code.

What are the possible causes of the P1A29 fault code?

If you’re experiencing the P1A29 fault code, your engine light may be on. This could be due to 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, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P1A29 fault code?
