P0AB5 - OBD Trouble Code

<<See All OBD Codes

What causes the P0AB5 error to get stored in the vehicle? Are you looking for this information? Then you are in the right place. Keep reading. The hybrid battery air temperature sensor 'B' circuit arises due to a faulty high voltage control module. The battery pack air temperature sensor keeps informing the high voltage control module about the temperature of the ambient air which is found in and around the hybrid battery pack. The error code P0AB5 will be set in the hybrid battery pack air temperature sensor if an incorrect signal is found by the high voltage control module Most vehicle will have this temperature sensor as a component of the battery pack assembly

You might notice that the HV battery assembly already has the intake air temperature sensor. When the intake air temperature keeps altering, the resistance valve also alters. Both the intake air temperature sensor and the battery temperature sensor will have identical features. The signal from the intake air temperature sensor will be used by battery ECU so that it can adjust the air flow speed of battery blower assembly.

What causes this problem with the Hybrid Battery Pack Air Temperature Sensor "B" Circuit Intermittent/Erratic?

• The HV battery assembly might seem to be defective.
• You might find an opening in the HV battery assembly harness or the circuit might be shorted.
• The electrical connection might be poor in the HV battery assembly.
• Failure of the battery ECU.

1. Engine Control Module - Is the performance of the engine very poor? Does your engine keep stalling very often? Then the ECM might be faulty which needs replacement as soon as possible.
2. Powertrain Control Module - The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly.
3. HV Battery Assembly - Are you looking for a replacement for your defective HV battery assembly? Get it from PartsAvatar as the best prices.
4. Hybrid Battery Pack - The hybrid battery packs are usually covered with lithium phosphate and they are designed to be smaller and lighter in weight than usual batteries. Any damage to this hybrid battery pack will need an immediate replacement.
5. Battery - One of the common symptoms for a damaged battery is the illumination of the check engine. Change it as soon as possible.

Interested in knowing the symptoms to OBD Code P0AB5? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this problem.

Common Symptoms

• High fuel consumption.
• Possible symptoms of a misfire.
• Blinking of the engine light as well as the warning light of the service engine.
• Reduced engine performance.

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue, you need to follow certain steps, and to solve OBD error code P0AB5, you will need to undergo the following replacements:

• Replacing the damaged hybrid battery pack.
• The corroded battery cables need replacement.

You might need to undergo a few more replacements. You might need HV Battery Assembly, HV Battery Assembly Harness, Battery ECU, and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• The P0AB5 diagnostic trouble code is not very difficult to diagnose or carry out
• If this error code appears in your vehicle it is always best to have a qualified technician or mechanic to look at this error code, where he will use a scanner to find out the problem.
• With the help of a scanner, the mechanic will recover every of the stored codes and freeze frame data by connecting it to the diagnostic port of the vehicle.
• Initially, the mechanic will begin by checking the hybrid battery pack and hybrid battery pack assembly as it can cause issues in your vehicle. Also, they can be one of the reasons if the error code is stored in the vehicle.
• After this, the mechanic will look after the components like battery cables, battery control module, battery current sensor, for any damages and defects.
• Necessary repairs will be carried out if they are defective.
• Finally, the engine control module/ powertrain control module will be inspected for any damages.
• Once every diagnosis and repairs are properly done, it is very important to retest the code and test drive the vehicle to see if the error codes, still appear and if the engine light keeps blinking.

Common Mistakes When Diagnosing the P0AB5 Code

• Damaged high voltage battery assembly.
• An issue might arise due to faulty wires.
• Low-level engine oil.
• Malfunctioning high voltage control module.
