P0A5F OBD Error Code: Problem & Solutions

<<See All OBD Codes

Stressed? See the error code P0A5F flashing? Well, all you gotta do is read the information we have written below. “Drive motor "A" phase U current high” is what is generally referred to determine the OBD-II code high voltage system may not operate. The current flowing through the high voltage cables is constantly monitored by sensors utilized by the high voltage control module. If a malfunction is detected in the current monitoring sensors by the high voltage control modules, the error code P0A5F is stored.

It should be noted that the high-voltage direct current of the HV battery and the alternating current for the MG1/MG2 is constantly being converted by the inverter. A three-phase bridge circuit which has 6 power transistors each for the MG1 and the MG2 converting the direct current and the three-phase alternating current are installed in the inverter itself. The HV control ECU play the role of controlling the actuation of the power transistors. The inverter imparts information that is imperative for effecting control like the amperage and voltage to the HV control ECU. The amperage that flows through the V and W phase cables between the inverter and MG1/MG2 is identified by the motor inverter current sensors. In order to identify a fault in the sensor system the HV control ECU controls the inverter current sensors.

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

• A defective generator current sensor
• Disconnected or short circuited generator current sensor harness
• A deficient electrical connection in the generator current sensor circuit

If you are facing OBD error code P0A5F, 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

• Slow engine on acceleration. Also, the light may flash on or erratically turn on as the DPF restarts
• A broken PCM
• The ECU displaying a "Limp Home Mode" until the error is corrected, If the DPF has not been absolved
• Deteriorating fuel efficiency

Wishing to combat the error code P0A5F? Here listed are a few steps that need to be followed to avoid or overcome the OBD error code P0A5F:

• Repair or replace a defective generator current sensor
• All the electrical parts should be visually checked. All the harness that are open or shorted should be mended or restored
• Also, a bad electrical connection should also be changed or repaired immediately

Thinking of where to start? How to diagnose the error code accurately? Well, then you should follow these steps in order to diagnose this fault code:

One should begin with a customary OBD-II trouble code scanner that should be employed to diagnose this trouble code P0A5F. This scanner should be used to verify and view the freeze frame data and assess the code by a qualified mechanic. The mechanic should also check for additional trouble codes stored too. After the repairs have been successfully performed, the codes should be cleared and the vehicle should be test driven to see if the code recurs. If the code vanish it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing The P0A5F Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P0A5F:

• A malfunctioning inverter/converter assembly
