Common Questions
What does P0564 mean and how does it affect my car?
The P0564 code indicates an intermittent issue with the cruise control system's input circuit. This can lead to problems with maintaining speed and can affect your vehicle's overall handling. It's important to address this code promptly to ensure the safety and reliability of your driving experience.
What are the most common causes of P0564 and how much does it cost to fix?
Common causes of P0564 include a faulty cruise control switch, damaged wiring, and an issue with the ECM. Repair costs can range from $150 for a switch replacement to over $1,500 for an ECM replacement.
Can I drive my car with P0564 or should I stop immediately?
While it might be possible to drive your vehicle with this code, it's not advisable. The cruise control system's failure can lead to unexpected acceleration or speed changes, which can be dangerous.
How can I diagnose P0564 myself using GeekOBD APP?
To diagnose P0564, connect the GeekOBD APP to your vehicle's OBD2 port. Run a scan to retrieve codes, and check the freeze frame data for context. Inspect the cruise control switch and wiring for any visible issues.
What vehicles are most commonly affected by P0564?
P0564 is commonly found in vehicles such as the 2015-2018 Ford F-150 and the 2014-2019 Chevrolet Silverado. Always check for any recalls or Technical Service Bulletins (TSBs) related to the cruise control system for your specific make and model.
How can I prevent P0564 from happening again?
Regular maintenance of your vehicle’s electrical systems can help prevent P0564. Check wiring and connectors for wear, and keep the cruise control switch clean and functional. Additionally, having your vehicle inspected regularly can help catch issues before they escalate.
What is P0564?
The diagnostic trouble code (DTC) P0564 indicates a problem with the cruise control system's input circuit, specifically referring to an intermittent signal. This code is typically triggered when the Engine Control Module (ECM) detects an inconsistency in the cruise control system's signals. In simpler terms, your vehicle's cruise control may not be functioning properly, which can lead to issues with maintaining speed or unexpected acceleration. This is not just an inconvenience; it can potentially pose safety risks while driving. For instance, if the cruise control system fails while you are on the highway, it could lead to erratic vehicle speed, making it difficult to control the car and increasing the chance of an accident. Common symptoms include the cruise control light flashing or staying on, along with difficulty engaging the system. In some vehicles, the malfunction could also affect other systems, leading to a lack of power steering or braking assist. Addressing this issue promptly is crucial for both your safety and the longevity of your vehicle's systems.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0564 is present:
- The cruise control light on your dashboard may be flashing or constantly illuminated, indicating a malfunction.
- You may notice that the cruise control system fails to engage, causing frustration during long drives.
- Drivers often report erratic vehicle speeds, where the car may accelerate or decelerate unexpectedly.
- In some cases, a check engine light may illuminate along with the P0564 code, indicating a broader issue.
- You might experience difficulty in controlling the vehicle, particularly in maintaining a constant speed.
Possible Causes
Most common causes of P0564 (ordered by frequency):
- The most common cause of P0564 is a faulty cruise control switch, which has a likelihood of around 40%. This switch can wear out over time, leading to intermittent connectivity issues.
- Another prevalent issue is damaged wiring or connectors in the cruise control circuit. These could be frayed or corroded, leading to inconsistent signals being sent to the ECM.
- A malfunctioning ECM could also trigger this code, but this is less common. If the ECM itself has issues, it may misinterpret signals from the cruise control system.
- Less commonly, a malfunctioning brake switch can cause P0564 by interrupting the cruise control functionality, as the system relies on this switch for safe operation.
- In rare cases, environmental factors such as moisture or extreme temperatures can affect electronic components, leading to intermittent faults.

Diagnostic Steps
Professional P0564 Diagnosis Process
Follow these systematic steps to accurately diagnose P0564. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Start with an initial visual inspection
Step 1: Start with an initial visual inspection. Check for obvious signs like damaged wiring, loose connections, or corrosion in the cruise control circuit. This should take about 5-10 minutes.
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan
Step 2: Use the GeekOBD APP to perform an OBD2 scan. Retrieve all codes and freeze frame data to gain context about the fault, which should take around 10-15 minutes.
Step 3: Step 3: Conduct component testing
Step 3: Conduct component testing. Utilize a multimeter to check the voltage and resistance of the cruise control switch and associated wiring. This step may take 20-30 minutes.
Step 4: Step 4: Perform a system function test
Step 4: Perform a system function test. After making any repairs, verify the proper operation of the cruise control system and clear the codes using the GeekOBD APP. This could take another 10-15 minutes.
Step 5: Step 5: Finish with a road test
Step 5: Finish with a road test. Drive the vehicle under various conditions to confirm that the cruise control system works correctly, which can take 15-20 minutes.
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
