This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady reading from the sensor that checks how hot the transmission fluid is. It's like when a thermometer keeps changing numbers quickly, and you're not sure what the real temperature is.
The transmission fluid temperature sensor helps the vehicle's computer monitor and manage the temperature of the transmission fluid. An intermittent circuit means the signal is not stable, which can cause issues with transmission performance.
The P275E code is triggered when the powertrain control module (PCM) detects an intermittent signal from the transmission fluid temperature sensor 'D'. This sensor is responsible for monitoring the temperature of the transmission fluid to ensure optimal performance and prevent overheating. An intermittent circuit can lead to improper transmission operation.
• Check Engine Light illuminated
• Erratic transmission shifting
• Transmission overheating
• Faulty transmission fluid temperature sensor
• Damaged or corroded wiring/connectors
• Poor electrical connection in the sensor circuit
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission fluid temperature sensor for proper operation.
• Replace the faulty transmission fluid temperature sensor.
• Repair or replace damaged wiring/connectors.
• Ensure all electrical connections are secure.
• OBD-II scanner
• Multimeter
• Basic hand tools (e.g., screwdrivers, pliers)

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check and maintain transmission fluid levels.
• Inspect wiring and connectors for wear and tear.
• Schedule routine vehicle maintenance.
Sensor Issue
• Drive cautiously and avoid heavy loads until the issue is fixed.
• Schedule a repair appointment with a qualified mechanic.
Check your vehicle's warranty coverage for powertrain components, which may include the transmission sensor.
P275E is a relatively common code related to sensor issues in vehicles with automatic transmissions, often due to aging components or wiring problems.
Moderate – While the vehicle may still be drivable, addressing the issue promptly can prevent further transmission damage.
Ignoring this code may lead to transmission damage, which can be costly to repair. Always ensure your vehicle is safe to drive.
• Vehicle at operating temperature
• Transmission in drive
The transmission fluid temperature sensor is typically located inside the transmission or on the transmission housing.
Q: Can I drive with a P275E code?
A: While you may be able to drive, it's not recommended as it can lead to further transmission issues.
Q: How do I know if my transmission fluid temperature sensor is bad?
A: Symptoms include erratic shifting, transmission overheating, and the Check Engine Light being on.
