Error Code P0A5E: What It Means & What To Do?

<<See All OBD Codes

Error code P0A5E? Don’t know what to do about it? Well, we have a solution for all your problems. Here’s all you need to know about the error code. It should be noted that the OBD-II code high voltage system may not operate is commonly referred to as a drive motor "A" phase u current low. Also, sensors are employed by the high voltage control module to regulate the current flowing through the high voltage cables. The code P0A5E is stored when if the high voltage control module identifies a malfunction in the current monitoring sensors.

Generally, the task of converting the high-voltage direct current of the HV battery and the alternating current for the MG1/MG2 is performed by the inverter. The inverter is equipped with a three-phase bridge circuit that further contains 6 power transistors each for the MG1 and the MG2 for the purpose of converting the direct current and the three-phase alternating current. The actuation of the power transistors is controlled by the HV control ECU controls. The information that is highly essential for effecting control such as the amperage and voltage to the HV control ECU is transferred by the inverter. The amperage that flows through the V and W phase cables between the inverter and MG1/MG2 is constantly notified by the motor inverter current sensors. Next, the task of transmitting the information that is imperative for effecting control such as the amperage and voltage to the HV control ECU is performed by the inverter. It can be observed that the HV control ECU regulates the inverter current sensors to identify a fault in the sensor system.

What causes this problem with the Drive Motor "A" Phase U Current Low?

• A distorted generator current sensor
• A corroded or shorted generator current sensor harness
• A powerless electrical connection in the generator current sensor circuit

If you are facing OBD error code P0A5E, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Often, the light may illuminate or light jerkily as the DPF refreshes. also, the engine may at times can be observed to be slow on acceleration.
• A defective PCM
• The ECU may turn on to the "Limp Home Mode" until it is treated If the DPF is not cleared
• A decreasing fuel efficiency

Learn the ways with which you can correct this trouble code:

• Replace or repair a malfunctioning generator current sensor as per the requirements
• All the electrical elements should be visually inspected. Any corroded or loose harness in the generator current sensor should be restored or mended
• Steps should be taken to restore a bad electrical connection in the generator current sensor circuit

Here’s how you can diagnose the error code P0A5E:

To start with you should connect the scanner to the vehicle diagnostic connector and restore all the codes stored along with the freeze frame data. It should be noted that while the red voltmeter lead that should be connected to IMRC valve power wire and the black voltmeter lead connected to the ground the valve should remain disconnected. Check on if any cylinders are misfiring, if the engine shows a miss without a code. Spray or pour water in small amounts on each cylinder exhaust port if the exhaust manifold is visible. It can be observed that the water on good cylinders can be seen evaporating immediately and slowly on the missing cylinders. After all this has been done, and you still fail to complete the task, the plugs should be pulled and the condito should be checked too.

Common Mistakes When Diagnosing The P0A5E Code

Stressed? Scared of misdiagnosing the error code? Well, we have listed here a few common mistakes that should be avoided:

• A fault due to the IC circuit high voltage
• A malfunction in the control module throttle actuator position
• Errors with the air conditioning (A/C) clutch feedback circuit high voltage
• Problems with the cruise vehicle speed/set speed difference too high
• The PCM stack might at times just overrun
