P2744 Code - Transmission Fluid Temperature Sensor 'B' Circuit Intermittent
Quick Answer
The P2744 diagnostic trouble code refers to the Transmission Fluid Temperature Sensor 'B' Circuit Intermittent. Common causes include Faulty Sensor: The transmission fluid temperature sensor itself may be faulty and need to be replaced, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the sensor can cause intermittent signals, ECM Malfunction: A malfunctioning engine control module (ECM) may not be able to properly interpret the signals from the sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2744 Description
The P2744 diagnostic trouble code refers to the Transmission Fluid Temperature Sensor 'B' Circuit Intermittent. This code indicates that there is an intermittent issue with the transmission fluid temperature sensor in the vehicle. The transmission fluid temperature sensor is responsible for monitoring the temperature of the transmission fluid and sending this information to the vehicle's engine control module (ECM). The ECM uses this data to adjust various parameters related to the transmission, such as shift points and torque converter lockup.
Common Causes of P2744
- Faulty Sensor: The transmission fluid temperature sensor itself may be faulty and need to be replaced.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the sensor can cause intermittent signals.
- ECM Malfunction: A malfunctioning engine control module (ECM) may not be able to properly interpret the signals from the sensor.
- Fluid Contamination: Contaminated transmission fluid can affect the sensor's readings and cause intermittent issues.
Symptoms of P2744
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Erratic Shifting: The transmission may experience erratic shifting patterns, such as delayed or harsh shifts.
- Decreased Fuel Efficiency: A faulty transmission fluid temperature sensor can cause the vehicle to consume more fuel than usual.
- Transmission Overheating: In severe cases, the transmission may overheat due to inaccurate temperature readings from the sensor.
How to Fix P2744
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and perform a thorough inspection of the transmission fluid temperature sensor and its wiring.
- Replace the Sensor: If the sensor is found to be faulty, replace it with a new one following the manufacturer's guidelines.
- Check Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections, and repair or replace as needed.
- Clear Codes: After completing the repair, clear the trouble codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2744
The cost of repairing a Transmission Fluid Temperature Sensor 'B' Circuit Intermittent issue can vary depending on the make and model of the vehicle, the location of the repair shop, and the cost of parts. On average, the cost of replacing a transmission fluid temperature sensor ranges from $100 to $200, including parts and labor. Additional costs may apply if there are wiring issues that need to be addressed. It is recommended to consult with a professional mechanic for a more accurate cost estimate based on your specific vehicle. Labor rates at auto repair shops typically range from $80 to $150 per hour.
