If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2744 fault code. Here are the symptoms to look out for:

  • The P2744 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include harsh shifting, transmission slippage, decreased fuel efficiency, and decreased engine performance.
  • Additionally, the vehicle may experience difficulty shifting gears, and the transmission may fail to engage or disengage properly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2744 fault code can be caused by a faulty sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2744 can be caused by a faulty transmission fluid temperature sensor.
  • It can also be caused by an open or shorted transmission fluid temperature sensor harness.
  • Additionally, a poor electrical connection in the transmission fluid temperature sensor circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2744, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code P2744, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2744 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P2744 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2744 code is related to the Automatic Transmission Fluid (ATF) Temperature Sensor. This sensor converts the fluid temperature into a resistance value. The Transmission Control Module (TCM) monitors the ATF Temperature Sensor signal and sets the OBDII code when the signal is out of factory specifications.

The P2744 code specifically refers to the ‘B’ circuit of the Transmission Fluid Temperature Sensor and indicates an intermittent issue. If this code is detected, it is important to have the sensor and circuit checked and repaired as necessary to ensure proper transmission function.

What are the possible causes of the P2744 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2744 fault code. This code is caused by a faulty transmission fluid temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2744 fault code?

If you’re experiencing the P2744 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Transmission Fluid Temperature Sensor or an open or shorted harness. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and allow you to take the necessary steps to fix the problem.

What are the signs of damaged components or broken, bent, pushed out, or corroded connector’s pins that I should look for when fixing the P2744 fault code?

If you’re fixing the P2744 fault code, you should look for signs of damaged components or broken, bent, pushed out, or corroded connector’s pins. These issues can cause the Transmission Fluid Temperature Sensor harness to be open or shorted, leading to the engine light turning on. To fix the issue, visually inspect the related wiring harness and connectors, and check for any damage or corrosion.
