This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor in your car that measures how hot the transmission fluid is. It's not working right, and the car's computer noticed.
The P2741 code is triggered when the Powertrain Control Module (PCM) detects a problem with the transmission fluid temperature sensor B circuit, indicating that the sensor is not operating within its expected range.
The Transmission Fluid Temperature (TFT) Sensor B is used by the PCM to monitor the temperature of the transmission fluid. This information helps the PCM control transmission operation. If the sensor's output is not within the expected range, the PCM sets the P2741 code.
• Check Engine Light is on
• Transmission may shift harshly
• Erratic transmission operation
• Poor fuel economy
• Faulty transmission fluid temperature sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connection at the sensor
• Faulty PCM (rare)
PCM: Powertrain Control Module, the vehicle's computer that controls engine and transmission functions.
TFT Sensor: Transmission Fluid Temperature Sensor, a device that measures the temperature of the transmission fluid.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the transmission fluid temperature sensor with a multimeter.
• Check the PCM for faults.
• Replace the transmission fluid temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the codes and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check transmission fluid levels.
• Inspect wiring and connectors for damage.
• Perform routine maintenance on the transmission system.
Sensor Issue
• Avoid driving the vehicle hard until the issue is fixed.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle's manufacturer for warranty coverage on transmission components.
This code has been associated with various transmission performance issues and is commonly reported in vehicles with high mileage.
Moderate – It's important to address this issue to prevent potential transmission damage.
Driving with a faulty transmission sensor can lead to increased wear and potential safety hazards.
• Engine running
• Vehicle at normal operating temperature
The transmission fluid temperature sensor is typically located inside the transmission or on the transmission housing.
Q: Can I drive with a P2741 code?
A: It's not recommended to drive for extended periods, as it may cause further damage to the transmission.
Q: How is the transmission fluid temperature sensor tested?
A: A multimeter is used to check the sensor's resistance and compare it to the manufacturer's specifications.
