Common Questions

What does P0575 mean and how does it affect my car?

The P0575 code indicates a malfunction in the cruise control switch circuit, affecting the ability to maintain speed without using the accelerator. This can lead to discomfort during long trips and may compromise driving safety if cruise control behaves erratically.

What are the most common causes of P0575 and how much does it cost to fix?

Common causes include a faulty cruise control switch, damaged wiring, or issues with the ECM. Repair costs can vary, with switch replacements typically ranging from $100 to $300, depending on labor and parts.

Can I drive my car with P0575 or should I stop immediately?

While you may still drive your vehicle, it's advisable to avoid using cruise control until the issue is resolved. Ignoring this code can lead to more severe problems down the line.

How can I diagnose P0575 myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for DTCs, view freeze frame data, and monitor live data from the cruise control system to help identify the root cause of the P0575 code.

What vehicles are most commonly affected by P0575?

Vehicles like the 2015-2018 Honda Accord, 2013-2018 Toyota Camry, and some Ford models frequently experience the P0575 code, often due to similar cruise control design and electrical systems.

How can I prevent P0575 from happening again?

Regular maintenance checks of your vehicle's electrical system, ensuring connections are clean and secure, can help prevent future occurrences of P0575. Additionally, keeping an eye on any electrical system warning signs can help catch issues early.

What is P0575?

The diagnostic trouble code (DTC) P0575 refers to a malfunction in the cruise control switch circuit. This code indicates that the Engine Control Module (ECM) has detected an issue with the input signals from the cruise control switch. The cruise control system is designed to help maintain a vehicle's speed without the driver needing to apply the accelerator pedal. When the P0575 code is triggered, it may be due to a faulty cruise control switch, damaged wiring, or issues within the ECM itself. Car owners may notice that the cruise control feature is inoperative or behaves erratically, which can lead to discomfort and potential safety issues during long drives. In practical terms, it’s essential to address this code promptly, as it not only affects driving convenience but can also point to underlying electrical issues that may worsen over time. Common vehicles affected by P0575 include models from Honda, Toyota, and Ford, particularly those produced between 2010 and 2018. Ignoring this code can lead to more severe electrical problems or even affect vehicle performance in terms of fuel efficiency and drivability.

Symptoms

Common symptoms when P0575 is present:

  • Check engine light stays on constantly, indicating a persistent issue that needs attention.
  • Cruise control fails to engage or disengage properly, making long drives more exhausting and less safe.
  • Unresponsive acceleration while using cruise control, which can lead to sudden speed changes unexpectedly.
  • Erratic cruise control behavior, such as accelerating or decelerating unexpectedly without driver input.
  • Increased fuel consumption, potentially due to the malfunction affecting engine performance.

Possible Causes

Most common causes of P0575 (ordered by frequency):

  1. The most common cause of P0575 is a faulty cruise control switch, which has a likelihood of about 60%. This switch is responsible for sending signals to the ECM, and when it fails, it disrupts the cruise control operation.
  2. Another potential cause is damaged wiring or connectors within the cruise control circuit, which can account for around 25% of cases. Corrosion or wear can lead to intermittent signals, causing erratic cruise control behavior.
  3. Less common causes may include issues with the ECM itself, which can lead to incorrect processing of the cruise control signals. This is rarer, at a likelihood of about 10%, but can lead to significant repair costs if the ECM needs replacement.
  4. A malfunctioning brake pedal switch can also trigger this code, as it sends signals to the cruise control system to disengage when the brakes are applied.
  5. Lastly, while rare, software issues within the vehicle's onboard computer system can also cause the P0575 code to trigger, requiring a software update or reprogramming.
