This summary uses the existing diagnostic information shown in full below.
This code means that the motor that helps move the transmission fluid in the car is getting too hot.
The P0DE4 code indicates that the electric or auxiliary transmission fluid pump A motor has exceeded its normal operating temperature range.
The electric or auxiliary transmission fluid pump is responsible for circulating transmission fluid through the transmission system, especially in hybrid or electric vehicles. When the motor of this pump overheats, it can lead to reduced efficiency or failure of the pump, potentially affecting the transmission's operation.
• Check engine light is on
• Transmission overheating warning
• Reduced transmission performance
• Faulty transmission fluid pump motor
• Low transmission fluid level
• Blocked or restricted transmission fluid passages
Transmission Fluid: A lubricant used to keep the transmission system running smoothly.
OBD-II Scanner: A tool used to read diagnostic trouble codes from a vehicle's computer.
• Check the transmission fluid level and condition.
• Inspect the transmission fluid pump motor for damage or wear.
• Check for any blockages in the transmission fluid lines.
• Replace the faulty transmission fluid pump motor.
• Refill or replace transmission fluid if low or contaminated.
• Clear any blockages in the transmission fluid lines.
• OBD-II scanner
• Transmission fluid level gauge

Moderate
• Toyota Prius
• Chevrolet Volt
• Ford Fusion Hybrid
• Regularly check and maintain transmission fluid levels.
• Schedule periodic transmission system inspections.
• Avoid overloading the vehicle.
Transmission Performance
• Do not ignore the check engine light.
• Avoid driving the vehicle until the issue is resolved.
• Consult a professional mechanic for a thorough inspection.
Check with the vehicle manufacturer for warranty coverage on transmission components.
This code has been more prevalent in hybrid and electric vehicles due to their reliance on electric auxiliary systems.
High – Continued driving with this issue can lead to transmission damage.
Ignoring this issue can lead to transmission failure, which may cause unsafe driving conditions.
• Vehicle must be in operation for a period to reach normal operating temperatures.
• Ensure the vehicle is on a level surface when checking fluid levels.
The electric/auxiliary transmission fluid pump is typically located near the transmission assembly.
Q: Can I drive my car with a P0DE4 code?
A: It's not recommended to drive with this code active, as it can lead to further damage.
Q: How do I reset the check engine light after fixing the issue?
A: Use an OBD-II scanner to clear the code after repairs are completed.
