This summary uses the existing diagnostic information shown in full below.
This code means that there's a problem with the electric pump that helps move the transmission fluid in your car. It's like if a water pump in a fish tank stopped working properly.
The code indicates an issue with the current draw of the auxiliary transmission fluid pump B motor, which could be due to electrical or mechanical problems.
P276D is triggered when the powertrain control module (PCM) detects an abnormal current draw from the auxiliary transmission fluid pump B motor. This could be due to a malfunction in the electric motor, a short circuit, or a mechanical failure within the pump itself.
• Transmission overheating
• Poor transmission performance
• Illuminated check engine light
• Faulty electric transmission fluid pump
• Wiring issues such as shorts or open circuits
• Faulty PCM or TCM (Transmission Control Module)
PCM: Powertrain Control Module
TCM: Transmission Control Module
• Use a scan tool to check for additional codes.
• Inspect the wiring and connectors for damage.
• Test the pump motor for proper operation and current draw.
• Replace the faulty electric transmission fluid pump.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM/TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Fusion
• Chevrolet Volt
• Toyota Prius
• Regular maintenance of the transmission system.
• Check and replace transmission fluid as recommended.
• Inspect wiring and connections periodically.
Sensor Issue
• Avoid driving the vehicle until the issue is fixed to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check your vehicle's warranty for coverage on transmission components.
This code has been more prevalent in hybrid and electric vehicles due to their reliance on electric pumps for transmission fluid circulation.
Moderate – It should be addressed soon to avoid potential transmission damage.
Driving with this code active could lead to transmission failure, which is a safety risk.
• Vehicle must be running.
• Transmission fluid temperature should be within normal operating range.
The auxiliary transmission fluid pump is usually located near the transmission or integrated within it.
Q: Can I drive with a P276D code?
A: It's not recommended to drive with this code active, as it may lead to transmission damage.
Q: How do I reset the P276D code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
