  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable increase in exhaust emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code u2629 can be caused by a range of issues, including a faulty sensor, poor electrical connection, and a malfunctioning control module.

  • The automobile fault code U2629 can be caused by a faulty Reductant Tank Temperature Sensor 1.
  • It can also be caused by an open or shorted Reductant Tank Temperature Sensor 1 harness.
  • Poor electrical connection in the Reductant Tank Temperature Sensor 1 circuit can also trigger the fault code.
  • Lastly, a faulty Reductant Control Module can also be a cause of the U2629 fault code.

Below are some possible fixes for the automobile fault code u2629, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u2629, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check 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 U2629 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of U2629 will be between $75 and $150, depending on the repair time required.

The U2629 fault code indicates a communication problem between the reductant control module and the reductant tank temperature sensor 1. The reductant control module is responsible for managing the reductant injection system, which helps reduce harmful emissions. The temperature sensor 1 is used to monitor the temperature of the reductant tank, which is important for proper system operation.

If the reductant control module cannot communicate with the temperature sensor 1, it may not be able to properly manage the reductant injection system, which could result in increased emissions and decreased fuel efficiency.
