If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a59 fault code.

Here are the symptoms to look out for:

  • The P1A59 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 P1A59 fault code in automobiles can be caused by a faulty battery pack, open or shorted battery pack harness, or poor electrical connection.

  • The automobile fault code P1A59 can be caused by a faulty battery pack.
  • It can also be caused by an open or shorted battery pack harness.
  • Additionally, a poor electrical connection in the battery pack circuit can also trigger this fault code.

To fix the p1a59 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1a59, 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 automobile fault code P1A59 is a diagnostic trouble code related to the hybrid battery pack cooling system. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code is dependent on the hourly rate charged by the auto repair shop. The average hourly rate charged by most auto repair shops is between $75 and $150.

Therefore, the cost of fixing the P1A59 fault code can range from $75 to $150.

The P1A59 code is related to the Hybrid Battery Pack Voltage. The Battery Energy Control Module (BECM) monitors the voltage across the battery pack using 3 module voltage sensors. If there is a deviation in the voltage or if one module within the battery pack is bad, it will result in a high Delta V SOH (state of health).

This fault code indicates that there is an issue with the hybrid battery pack voltage, which could affect the performance of the vehicle. It is important to get this issue diagnosed and fixed as soon as possible to avoid further damage.

What are the possible causes of the P1A59 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A59 fault code. This code is usually caused by a faulty battery pack, an open or shorted battery pack harness, or a poor electrical connection in the battery pack circuit. To fix this 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.

How can I visually inspect the related wiring harness and connectors to fix the P1A59 fault code?

If you’re experiencing the P1A59 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Battery Pack, an open or shorted Battery Pack harness, or a poor electrical connection in the Battery Pack circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
