P0AAD - OBD Trouble Code

<<See All OBD Codes

Love travelling but hate these halts? See the error code P0AAD flashing? Don’t know what to do about it? Then you have just arrived at the right destination. Parts Avatar not only believes in offering premium quality products but also great services to the customers. Here we have written down all that you need to know about the error code P0AAD. This OBD-II code high voltage control module failure is also known as a hybrid battery pack air temperature sensor ‘A’ circuit range/performance. The battery pack air temperature sensor performs the function of updating the high voltage control module about the temperature of the ambient air in and around the hybrid battery pack. When the hybrid battery pack air temperature sensor transmits a wrong signal to the high voltage control module, it stores the error code P0AAD. On most of the high voltage vehicles, this temperature sensor can be found as a part of the battery pack assembly itself.

It should be noted that the air temperature sensor has an HV battery assembly installed. The resistance value of which differs with the changes in the intake air temperature. Also, the intake air temperature sensor and the battery temperature sensors share the set of features too. In order to adjust the air flow speed of the battery blower assembly, the battery ECU utilizes the signals from the intake air temperature sensor.

Still not getting it? Well, we have more in store for you!

What causes this problem with the Hybrid Battery Pack Air Temperature Sensor "A" Circuit Range/Performance?

• Defective HV battery assembly (intake air temperature sensor)
• The HV battery assembly harness that is loose or shorted
• Powerless electrical connection in the HV battery assembly circuit
• Failed battery ECU

1. HV Battery Assembly - Do you love hitting the roads like we do? But don’t know the reason behind these halts? It could be due to corroded or disconnected HV battery assembly. Perform amendments immediately if you want to travel endlessly.
2. Battery Cables - See the error code P0AAD? Don’t know what triggered the code? Fall in the MPG? Well, all this is likely caused due to shorted or malfunctioning battery cables. Don’t know where to shop from? Then you have just landed at the right destination.
3. Battery ECU - Noticing a sudden drop in the battery bars? Then you should immediately change your battery ECU. Log into Parts Avatar, your one stop destination for premium quality auto parts for your new battery ECU.
4. Battery Temperature Sensor - Observing a sluggish engine crank, engine stall, check engine light illuminated? Don’t know what to do? Tired of all these problems? Well, it could be due to a defect in the battery temperature sensor. Tune into Parts Avatar for your brand-new battery temperature sensor offered at best prices.

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on few common symptoms of OBD error code P0AAD:

Common Symptoms

• The engine light flashing on (or service engine soon warning light)

After you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle’s:

• Repair or replace a damaged HV battery assembly (intake air temperature sensor) immediately
• Ensure that all the corroded or loose harness in the HV battery assembly is mended or restored
• Steps should be performed to fix a bad electrical connection running in the HV battery assembly circuit to avoid problems
• A failed battery ECU should repair or replaced immediately

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade HV battery assembly, HV battery assembly harness, battery ECU and a lot more for our precious customers.

Here are some steps which you should follow in order to diagnose this fault code:

Start by using a scanner (or code reader) and a digital volt/ohmmeter as that will be helpful in precisely diagnosing this code-storing condition. Perform a visual inspection of system wiring, connectors, and components. Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in conventional working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. This information can be highly important in diagnosing intermittent conditions that may have stimulated the code being stored. After the codes are retested, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.

Common Mistakes When Diagnosing the P0AAD Code

Only for you we have listed here a few common mistakes that should be avoided while the diagnosis procedure is being performed:

• It should be noted that before performing the repairs the mechanic should go through the system thoroughly, as at times he may end up performing major repairs that are expensive and time taking while the code could have been solved by just repairing some minor faults.
• A malfunction in the generator current sensor.
