This code means that a part of the car that helps move the gears is spinning too fast. It's like a toy car's wheels spinning out of control.
The electric or auxiliary transmission fluid pump is operating at a speed higher than its normal range.
The P1A6E code indicates that the electric or auxiliary transmission fluid pump is running at a speed that exceeds its designed limits. This could be due to a malfunction in the pump control system or a mechanical issue within the pump itself.
• Check engine light is on
• Transmission slipping or not engaging properly
• Unusual noises from the transmission area
• Faulty transmission fluid pump
• Electrical issue in the pump circuit
• Faulty transmission control module (TCM)
