The P2744 fault code refers to an issue with the Transmission Fluid Temperature Sensor B Circuit. This sensor is critical for monitoring the temperature of the transmission fluid, ensuring optimal performance and preventing overheating. An intermittent fault indicates that the sensor may be giving inconsistent readings or there is a problem in the circuit that affects its functionality.

What are the symptoms of the P2744 code?

• Inconsistent shifts or delayed shifting of the transmission
• Transmission overheating warning lights may illuminate
• Reduced fuel efficiency due to improper transmission operation
• Erratic transmission behavior or unusual noises during operation
• Check Engine Light (CEL) activation indicating a fault code

What causes the P2744 code?

• Faulty Transmission Fluid Temperature Sensor B
• Wiring issues such as short circuits or poor connections
• Malfunctioning Engine Control Unit (ECU) or Transmission Control Module (TCM)
• Corrosion or damage in the transmission wiring harness
• Poor grounding of the circuit

How to fix P2744?

• Inspect and repair any damaged wiring or connectors associated with the Transmission Fluid Temperature Sensor B circuit.
• Test the Transmission Fluid Temperature Sensor B for proper function and replace if found faulty.
• Check for any related fault codes and address them appropriately as they may provide additional insight into the issue.
• Reset the ECU or TCM to clear any stored fault codes and monitor for reoccurrence of the fault.
• Ensure proper grounding and electrical connections throughout the circuit.
