What is U0E93?

DTC U0E93 is a diagnostic trouble code that indicates an issue with the communication between vehicle control modules, specifically related to the Hybrid Powertrain Control Module (HPCM). When this code is triggered, it usually indicates that the HPCM has detected a fault in one or more of the hybrid system components. This can lead to various performance issues, including poor acceleration, reduced fuel efficiency, and even possible engine shutdown in severe cases. For owners of affected models like the 2016-2020 Ford Explorer Hybrid, this can be concerning. If the vehicle inadvertently shuts down while driving, it poses a significant safety risk. The U0E93 code may also illuminate the check engine light, prompting drivers to seek a professional diagnosis. Understanding this code is crucial, as it can affect the hybrid system's efficiency and overall vehicle performance. In many cases, this can lead to costly repairs if not addressed promptly. It's advisable to consult a qualified technician who can read the codes, interpret the freeze frame data, and perform necessary repairs to ensure your vehicle operates efficiently and safely.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0E93 is present:

  • Check engine light illuminates consistently, indicating an underlying issue that requires immediate diagnosis.
  • Vehicle experiences reduced power during acceleration, making it difficult to merge into traffic or climb hills smoothly.
  • Fuel economy may decrease significantly, sometimes by 15-20%, which can lead to higher running costs.
  • Unusual noises may be present from the hybrid system, indicating potential mechanical failures or component issues.
  • In severe cases, the vehicle may enter a limp mode, limiting performance and requiring repair before normal operation can resume.

Possible Causes

Most common causes of U0E93 (ordered by frequency):

  1. The most common cause is a faulty Hybrid Powertrain Control Module (HPCM), which occurs in about 60% of cases. This module is crucial for managing the hybrid system's operations and can fail due to software issues or physical damage.
  2. Another potential cause is communication errors between modules, often due to wiring issues or damaged connectors. This can happen if the vehicle has been in an accident or if there has been exposure to moisture.
  3. A less frequent cause could be battery issues within the hybrid system. Battery degradation can lead to improper voltage levels, which can trigger the U0E93 code. Regular maintenance and checks can help prevent this.
  4. Corrosion on electrical connections, although less common, can severely disrupt communication between modules, leading to code U0E93.
  5. Rarely, a software glitch within the vehicle's systems could also cause this code to appear, often resolved with a software update.
