What is C0E38?

The DTC C0E38 code indicates a malfunction associated with the vehicle's powertrain control module (PCM), specifically tied to the vehicle's traction control system. This code is particularly prevalent in the 2016-2020 Ford Explorer models but can also appear in various other makes/models utilizing similar electronic systems. When the C0E38 code is triggered, it typically means that the PCM has detected an abnormal reading from a sensor related to traction control, which may lead to erratic vehicle behavior, especially during acceleration or slippery road conditions. Drivers may notice the traction control warning light illuminating on the dashboard, indicating a fault in the system's ability to provide optimal traction. The implications of ignoring this code can be significant; poor traction control can lead to reduced vehicle stability, especially in adverse weather conditions, and may ultimately affect the safety of the driver and passengers. Regular diagnostics and timely repairs are crucial to ensure that the traction control system functions as intended, helping maintain vehicle control and safety under various driving conditions.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0E38 is present:

  • The check engine light remains illuminated, indicating an ongoing issue with the vehicle's system.
  • The traction control light may flash intermittently, particularly during acceleration on wet or icy surfaces, suggesting that the system is struggling to maintain grip.
  • Drivers may experience a noticeable delay in throttle response, especially when trying to accelerate quickly, leading to hesitation in power delivery.
  • Increased tire slip during acceleration, especially noticeable when starting from a stop on slick surfaces.
  • Potential decrease in fuel economy due to the traction control system working harder to maintain stability.

Possible Causes

Most common causes of C0E38 (ordered by frequency):

  1. The most common cause of the C0E38 code is a faulty wheel speed sensor, which can occur in about 60% of cases. This sensor monitors the speed of each wheel and provides feedback to the PCM to adjust traction control accordingly.
  2. A malfunctioning PCM or software issue can also trigger this code, accounting for around 20% of instances. Updates or reprogramming may be required to resolve the issue.
  3. Wiring or connector issues, such as damaged wiring harnesses or corroded connectors, can lead to incorrect readings and are responsible for approximately 15% of cases. Regular inspections can help prevent these problems.
  4. Less common but serious causes include issues with the ABS module, which can impact the entire traction control system function and may require extensive diagnostics and repairs.
  5. A rare cause could be external interference from aftermarket modifications or devices that affect the vehicle's electronics, potentially leading to false readings.
