Drive Motor Phase W Current High
The P0A6E code indicates that the current in phase W of the drive motor is higher than the expected range. This is typically caused by a short circuit in the motor windings, a faulty inverter, or a malfunctioning motor control module. High current can lead to overheating and damage to the motor or inverter components.
01. Most Common Causes
- Short circuit in drive motor phase W winding
- Faulty inverter module
- Malfunctioning motor control module
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced motor power or performance
- Possible overheating of the drive motor
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Inspect the drive motor and inverter for visible damage or loose connections.
Step 3: Perform a motor winding resistance test to check for shorts.
Step 4: Test the inverter output and motor control module signals.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. High current can cause further damage to the motor or inverter, and may lead to a loss of power or fire hazard.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Repair costs vary widely depending on the cause, from a simple connector fix to replacing the motor or inverter, which can be much higher.
