What vehicles are most commonly affected by U0EE2?

This code is frequently seen in 2016-2020 Ford Explorers, but it can also affect other Ford models with similar electronic systems.

How can I prevent U0EE2 from happening again?

Regular maintenance, including inspecting wiring harnesses and ensuring software is up to date, can help prevent U0EE2 from recurring.

What is U0EE2?

DTC U0EE2 is a diagnostic trouble code that indicates a communication error between modules in your vehicle's network, specifically relating to the powertrain control module (PCM) and other electronic control units (ECUs). This code is most commonly seen in 2016 to 2020 Ford Explorer models, among others. When this error occurs, it means that the PCM is unable to receive or send data to other critical systems, such as the transmission control module or the anti-lock braking system. This disruption can lead to various performance issues, including stalling or poor acceleration, and can trigger the check engine light. If ignored, the communication error can result in further complications, impacting the vehicle's overall performance and safety. Owners may experience symptoms such as erratic shifting or unexpected engine behavior, making it essential to address the issue promptly to avoid more severe consequences down the line.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0EE2 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the vehicle's systems.
  • Engine hesitates during acceleration, leading to a frustrating driving experience.
  • Fuel economy decreased by 10-15%, which can significantly impact your monthly expenses.
  • Erratic shifting in automatic transmissions, causing uncomfortable driving conditions.
  • Increased difficulty starting the vehicle, especially in colder temperatures.

Possible Causes

Most common causes of U0EE2 (ordered by frequency):

  1. Faulty wiring or connectors, which account for approximately 40% of cases, often due to wear and tear or exposure to moisture.
  2. Software glitches in the ECU, which can be resolved through software updates or reprogramming.
  3. Faulty modules, where a failing ECU or PCM can lead to communication breakdown, making up about 20% of cases.
  4. Less common but serious cause could be a malfunctioning CAN bus, which is crucial for data exchange between modules.
  5. Rarely, a complete system failure due to severe electrical issues can also trigger this code.
