What is C0FE8?

DTC C0FE8 is a diagnostic trouble code indicating a malfunction related to the vehicle's powertrain control module (PCM). Specifically, this code often points to issues in the communication between the PCM and other critical vehicle systems such as the transmission control module (TCM) or the engine control module (ECM). When this code is triggered, it may lead to a range of performance issues, including erratic engine performance, stalling, or even the inability to start the vehicle altogether. This code is more frequently observed in models like the 2017-2021 Ford F-150 and other Ford vehicles equipped with similar electronic systems. Ignoring this code can lead to increased wear on engine components, reduced fuel efficiency, and potential safety hazards on the road. Therefore, it's crucial to address this issue promptly to ensure the vehicle operates smoothly and safely. If you're experiencing this code, it’s advisable to consult a professional technician who can conduct a thorough diagnostic assessment and execute the necessary repairs.

Symptoms

Common symptoms when C0FE8 is present:

  • The check engine light remains illuminated, indicating a persistent issue with the vehicle's performance.
  • You may notice the engine hesitating or stalling during acceleration, which can be frustrating and dangerous.
  • Fuel economy may decrease by approximately 10-15%, leading to increased costs at the pump.
  • The vehicle may exhibit erratic shifting patterns, particularly in automatic transmissions, affecting driving comfort and safety.
  • In some cases, the vehicle may fail to start altogether, leaving you stranded until the issue is resolved.

Possible Causes

Most common causes of C0FE8 (ordered by frequency):

  1. The most common cause of DTC C0FE8 is a faulty powertrain control module, which occurs in about 40% of cases. This can result from manufacturing defects or electrical issues.
  2. Another frequent cause is damaged wiring or connectors in the communication circuit, which can lead to intermittent faults. This accounts for about 30% of occurrences.
  3. Corrosion at connectors can also lead to communication failures; ensuring proper maintenance can prevent this issue.
  4. Less commonly, issues with the transmission control module can trigger this code, which may necessitate specialized diagnostic tools for accurate identification.
  5. In rare cases, software glitches within the PCM can cause DTC C0FE8 to appear, requiring software updates or resets.
