Use the GeekOBD APP to scan for trouble codes, check freeze frame data, and monitor real-time sensor data to identify issues affecting your cruise control system.
What vehicles are most commonly affected by P058E?
This code is commonly reported in vehicles like the 2015-2018 Ford Fusion and the 2016-2019 Honda Civic, among others.
How can I prevent P058E from happening again?
Regularly inspect your vehicle's electrical connections and wiring, ensure routine maintenance of the cruise control system, and keep an eye on any warning lights that may indicate emerging issues.
What is P058E?
The P058E code indicates a problem with the cruise control system's performance. This code is typically triggered when the vehicle's onboard diagnostics (OBD) system detects that the cruise control system is not functioning as expected. In practical terms, this means that when you try to engage the cruise control, it may not activate or may disengage unexpectedly. For many car owners, this could lead to a frustrating driving experience, particularly on long highway trips where cruise control is commonly used to maintain speed and improve fuel efficiency. The issue can stem from various components within the cruise control system, including the brake switch, throttle control, or the cruise control module itself. If left unresolved, it may not only affect your vehicle's comfort and fuel efficiency but could also lead to more severe issues with the engine or transmission over time. It's crucial to address this code promptly to ensure safe driving and optimal vehicle performance.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P058E is present:
- Check engine light stays on constantly, indicating a persistent issue with the cruise control system.
- Cruise control fails to engage or disengages unexpectedly, leading to inconsistent vehicle speed.
- Fuel economy decreased by 10-15%, as the vehicle may struggle to maintain speed without cruise control.
- Unusual sounds or vibrations when attempting to use the cruise control feature.
- Intermittent loss of throttle response when cruise control is engaged, creating potential safety hazards.
Possible Causes
Most common causes of P058E (ordered by frequency):
- Faulty brake switch (30% likelihood) - The brake switch may fail to send the correct signal to the cruise control module, preventing cruise control from engaging.
- Malfunctioning cruise control module (25% likelihood) - This unit controls the cruise system, and if it's defective, it may not operate correctly.
- Throttle position sensor issues (20% likelihood) - If this sensor is not providing accurate readings, it can affect cruise control functionality.
- Damaged wiring or connectors (15% likelihood) - Frayed wires or poor connections can disrupt communication between components.
- Less common cause: Software glitches in the vehicle's computer system can also trigger the P058E code.
