If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2741 fault code.

Here are the symptoms to look out for:

  • The P2741 fault code in an automobile can cause several symptoms, including the illumination of the engine light or service engine soon warning light.
  • Other symptoms may include issues with the transmission, such as harsh shifting or slipping gears.
  • The vehicle may also experience a decrease in fuel efficiency or a loss of power while driving.
  • Additionally, the car may have difficulty starting or may stall while idling.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2741 can be caused by various factors, including a faulty sensor or poor electrical connection.

  • The automobile fault code P2741 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 p2741, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code P2741, 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 P2741 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 P2741 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2741 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 P2741 code specifically refers to the Transmission Fluid Temperature Sensor ‘B’ Circuit RangePerformance.

If this code appears, it means that the sensor signal is not within the expected range, which could indicate a problem with the sensor or the transmission fluid temperature.

It is important to have this issue diagnosed and repaired promptly to avoid potential damage to the transmission.

What are the possible causes of the automobile fault code P2741?

If you see the engine light on or the service engine soon warning light, it could be due to the P2741 fault code. This code is usually 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’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P2741 fault code?

If you’re experiencing the P2741 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code is caused by a faulty Transmission Fluid Temperature Sensor, an open or shorted harness, or a poor electrical connection. To fix it, check the possible causes listed above and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

What are the signs that the Transmission Fluid Temperature Sensor harness is open or shorted, causing the P2741 fault code?

If you notice the engine light or service engine soon warning light is on, it could be due to a faulty Transmission Fluid Temperature Sensor or an open or shorted Transmission Fluid Temperature Sensor harness. To fix this issue, you should visually inspect the related wiring harness and connectors, checking for damaged components and broken, bent, pushed out, or corroded connector’s pins.
