What is P0ACE?

DTC P0ACE is a diagnostic trouble code that indicates a problem with the vehicle's electric power steering system. This code is particularly prevalent in vehicles like the 2015-2019 Ford F-150, where the power steering system is critical for safe maneuverability. When this code is triggered, it often means that the power steering module has detected an issue with the steering assist, which can lead to increased difficulty when steering, especially at low speeds. This can result in a safety hazard, as the driver may struggle to control the vehicle effectively. In many cases, the root cause of the P0ACE code can be traced back to electrical issues such as faulty wiring or connectors, a malfunctioning steering angle sensor, or even the power steering control module itself. Ignoring this code may lead to more severe steering problems over time, potentially resulting in costly repairs. Understanding the implications of the P0ACE code is crucial for vehicle owners to ensure safe driving conditions and to prevent further damage to the steering system.

Symptoms

Common symptoms when P0ACE is present:

  • Check engine light is illuminated, indicating a problem with the power steering system.
  • Steering feels stiff or unresponsive, especially during low-speed maneuvers.
  • Unusual noises such as groaning or whining when turning the steering wheel.
  • Electrical issues such as intermittent loss of power steering assist.
  • Difficulty maintaining a straight line while driving due to unstable steering response.

Possible Causes

Most common causes of P0ACE (ordered by frequency):

  1. The most common cause is a faulty power steering control module, which occurs in about 40% of cases. This module controls the electric assist and can fail due to wear or electrical faults.
  2. Another prevalent cause is a malfunctioning steering angle sensor, found in approximately 30% of vehicles showing this code. This sensor provides critical data about the steering wheel position to the control module.
  3. Wiring issues or poor connections account for about 20% of cases; frayed wires or loose connections can disrupt the electrical signals needed for proper steering function.
  4. A less common but serious cause could be a failure in the electric power steering motor itself, which can lead to complete loss of steering assist.
  5. Rarer causes include software glitches in the control module that may require an update to resolve.
