Common Questions
What does P058D mean and how does it affect my car?
The P058D code indicates a problem with your vehicle's cruise control system. It means the system can't maintain your set speed, which can lead to erratic driving conditions. If you ignore this code, it may result in increased fuel consumption and unsafe driving situations, especially on highways.
What are the most common causes of P058D and how much does it cost to fix?
The most common cause of P058D is a faulty cruise control module, which can cost between $200 and $500 to replace. Other causes include wiring issues, which may cost $50 to $150 to repair, and a faulty brake pedal switch, which can be replaced for $30 to $80.
Can I drive my car with P058D or should I stop immediately?
While you can technically drive with P058D, it is advisable to address it promptly. Driving with a malfunctioning cruise control system may pose safety risks, especially on long trips where speed maintenance is crucial.
How can I diagnose P058D myself using GeekOBD APP?
To diagnose P058D using the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Run a full scan to retrieve diagnostic codes, check freeze frame data for context, and look for other related codes that might help pinpoint the issue.
What vehicles are most commonly affected by P058D?
P058D is commonly found in Ford vehicles like the 2015-2018 F-150 and Chrysler models such as the 2017-2020 Pacifica. These vehicles have reported issues with their cruise control systems, and drivers should be aware of potential recalls or TSBs related to this code.
How can I prevent P058D from happening again?
To prevent P058D, regularly inspect and maintain your cruise control system, including checking wiring and connectors for wear and tear. Keep an eye on any dashboard warning lights, and ensure that any repairs are performed promptly to avoid further issues.
What is P058D?
Diagnostic Trouble Code (DTC) P058D indicates a malfunction in the cruise control system, specifically related to the system's ability to maintain speed. When this code is triggered, it usually points to issues within the cruise control module or its associated components. The cruise control system is designed to enhance driving comfort on long trips by allowing the driver to maintain a set speed without continuous input on the accelerator pedal. However, when the system malfunctions, it can lead to erratic speed control, potentially putting the driver at risk. Symptoms of this issue may include the cruise control not engaging, not maintaining the desired speed, or disengaging unexpectedly. It is crucial for drivers of affected vehicles, especially common models like the 2015-2018 Ford F-150 or 2017-2020 Chrysler Pacifica, to address this code promptly. Failure to do so may lead to further mechanical problems or complications during driving. A qualified technician should conduct a thorough diagnostic to identify the root cause and recommend the appropriate repairs. Ignoring this code can lead to increased fuel consumption and may affect the vehicle's overall performance.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P058D is present:
- Check engine light illuminates, indicating a malfunction in the cruise control system.
- Cruise control fails to engage, making it impossible to maintain a constant speed during highway driving.
- Cruise control disengages unexpectedly, leading to sudden speed changes that can be dangerous.
- Vehicle experiences erratic speed fluctuations, indicating potential malfunction within the cruise control module.
- Driver notices increased fuel consumption due to inability to maintain a steady speed.
Possible Causes
Most common causes of P058D (ordered by frequency):
- Faulty cruise control module (60% likelihood) - This is the most common cause and typically requires replacement.
- Wiring issues or damaged connectors (25% likelihood) - Corrosion or frayed wires can disrupt communication within the system.
- Faulty brake pedal switch (10% likelihood) - If the switch fails, it may send incorrect signals to the cruise control system.
- Less common cause: Failed throttle position sensor (3% likelihood) - This can result in poor communication with the cruise control.
- Rare cause: Software glitches in the vehicle's ECU (2% likelihood) - This is less frequent but may require a software update.
