If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p1b61 fault code.

Here are the symptoms to look out for:

  • The P1B61 fault code in an automobile 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 P1B61 fault code can be caused by a faulty battery pack or battery interface control module in hybridelectric vehicles.

  • The automobile fault code P1B61 can be caused by a faulty Hybrid/Electric Vehicle Battery Pack.
  • It can also be caused by a faulty Hybrid/Electric Vehicle Battery Interface Control Module.
  • These are the only two causes of this particular fault code.

Below are the possible fixes for the automobile fault code p1b61, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1b61, 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 automobile fault code P1B61 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the P1B61 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P1B61 code is related to the HybridElectric Vehicle battery pack.

The battery pack contains 288 cells grouped in parallel and series. There are three battery sections, each with a different number of cells and cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules. The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2.

The P1B61 code indicates a low voltage in the HybridElectric Vehicle Battery 42 Circuit.

What are the possible causes of the P1B61 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B61 fault code. This code is caused by a faulty hybrid/electric vehicle battery pack or a faulty hybrid/electric vehicle battery interface control module. 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.

How can one visually inspect the related wiring harness and connectors to fix the P1B61 fault code?

If you’re experiencing the P1B61 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Hybrid/Electric Vehicle Battery Pack or a faulty Hybrid/Electric Vehicle Battery Interface Control Module. 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. It’s important to check the “Possible Causes” listed above to ensure that you’re addressing the root cause of the issue.

What are the consequences of ignoring the P1B61 fault code and not fixing it in time?

Ignoring the P1B61 fault code, which indicates a faulty hybrid/electric vehicle battery pack or interface control module, can lead to serious consequences. The engine light or service engine soon warning light will remain on, indicating a problem with the vehicle’s battery system. This can result in reduced fuel efficiency, decreased power, and even complete failure of the battery system. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
