<<See All OBD Codes

Unable to comprehend the error code P0AAE? Don’t know what to about it or where to look for? Don’t worry, Parts Avatar has got your back! All you need to solve the error code P0AAE is this little guide by Parts Avatar about the error code P0AAE. This OBD-II code high voltage control module failure is also referred to as a hybrid battery pack air temperature sensor "A" circuit low. The driver can observe that the battery pack air temperature sensor plays the role of informing the high voltage control module about the temperature of the ambient air in around the hybrid battery pack. Whenever a false signal is transmitted from the hybrid battery pack air temperature sensor, the high voltage control module identifies that and sets the error code P0AAE. Generally, the temperature sensor can be found built within the battery pack assembly on most of the high voltage vehicles.

It should be noted that the HV battery assembly has an intake air temperature sensor installed. The resistance value of which is supposed to change with the variations in the intake air temperature sensor. The features of the intake air temperature sensor are the same as the battery temperature sensors. Further, the battery ECU employs the signals transmitted from the intake air temperature sensor for performing the adjustments in the air flow speed of the battery blower assembly.

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

• Malfunctioning HV battery assembly (intake air temperature sensor)
• Loose or shorted HV battery assembly harness
• HV battery assembly circuit bad electrical connection
• Defect in the battery ECU

1. HV Battery Assembly - The HV battery assembly if defective can lead to problems related to corrosion on the battery, slow emissions and engine stalling. Change or repair it now if you want to get rid of the error code P0AAE and these complications.
2. Battery Cables - Facing the error code P0AAE? Inferior quality battery cables can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P0AAE. Not only this you are likely to experience a loss of electrical power too. Tune into Parts Avatar for supreme quality battery cables at economical prices.
3. Battery ECU - A lot of unexplained symptoms are likely to be experienced as soon as the battery ECU gets damaged. The battery cables enable the supply of power in the entire system to work in tandem. So a fault in the battery ECU can affect not only a few parts but the functioning of the entire system. Tune into Parts Avatar for top notch sets of battery ECU.
4. Battery Temperature Sensor - Error code P0AAE? Don’t know the reason behind it? Well, it could be due to a possible malfunction in the battery temperature sensor. We advise you to repair or replace it now. Visit our site today for premium quality products!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P0AAE here:

Common Symptoms

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

Here are some ways with the help of which you will be able to correct the OBD code P0AAE:

• Repair or replace a malfunctioning HV battery assembly (intake air temperature sensor)
• Mend or restore a damaged battery ECU
• Make sure a poor electrical connection running in the HV battery assembly circuit should be mended
• All the burnt or disconnected harness in the HV battery assembly should be changed or repaired as soon as possible

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:

First and foremost, to begin with if you notice a clicking sound while starting the engine while the engine the fails to crack, it indicates at a malfunction within the battery such as a low or a completely discharged battery. It could also be burnt or open battery cables. On the other hand, if you start the car and the engine cranks, this could be indicative of an issue with the fuel or the ignition. Well, a number of other reasons triggering a bad engine also include a failed starter motor relay, a jammed fuel filter, a damaged fuel pump or a malfunctioning ignition switch. Make sure you check the functioning of the VCT solenoid. You should look for a sticking or jammed CT solenoid valve caused due to contamination. We advise you to consult specific repair manual in order to perform the component testing’s for the VCT unit.

Common Mistakes When Diagnosing the P0AAE Code

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

• Right 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.
• Defective wiring.
