Common Questions

What does U064E mean and how does it affect my car?

DTC U064E indicates a communication error in your vehicle’s system, meaning the engine control unit can’t communicate with other modules. This can lead to performance issues like stalling, poor acceleration, and reduced fuel economy. Addressing this quickly can help prevent further damage and improve safety.

What are the most common causes of U064E and how much does it cost to fix?

Common causes include faulty wiring (60%), malfunctioning modules (25%), and corroded connectors (10%). Repair costs range from $100 for wiring repairs to over $500 for module replacements, depending on the complexity of the issue.

Can I drive my car with U064E or should I stop immediately?

While some drivers may be able to drive short distances without noticeable problems, it’s not advisable. Ignoring this code can lead to more severe issues and safety concerns, so it’s best to have it diagnosed as soon as possible.

How can I diagnose U064E myself using GeekOBD APP?

Start by connecting the GeekOBD APP to your vehicle’s OBD2 port. Use the app to scan for error codes and retrieve freeze frame data. This will provide insight into when the issue occurs, helping you understand the context of the U064E code.

What vehicles are most commonly affected by U064E?

DTC U064E is frequently found in vehicles like the 2015-2018 Honda Civic and other models from manufacturers such as Toyota and Ford. Always check for any recalls or technical service bulletins that might relate to communication issues.

How can I prevent U064E from happening again?

Regular maintenance checks can help prevent wiring issues and module failures. Keeping your vehicle’s software updated and inspecting battery health can also reduce the likelihood of encountering DTC U064E.

What is U064E?

DTC U064E indicates a communication error between the vehicle’s modules, specifically related to the 'Vehicle Communication Network.' This code often arises when the powertrain control module (PCM) cannot communicate with other modules, such as the transmission control unit (TCU) or the anti-lock braking system (ABS) module. This disruption can lead to various performance issues, including erratic engine behavior, transmission problems, and even safety system malfunctions. Car owners may notice symptoms such as the check engine light illuminating, reduced fuel efficiency, or strange shifting patterns in their vehicles. In modern vehicles, especially those manufactured from 2015 to 2018, like the Honda Civic, accurate communication between these modules is critical for optimal performance. When DTC U064E is triggered, it’s essential to address it promptly, as ignoring this issue can lead to further complications, including increased repair costs and potential safety hazards. Drivers should be aware that this code can stem from a variety of underlying issues, such as wiring faults or failed modules, necessitating a thorough diagnostic process to pinpoint the specific cause and implement a suitable repair solution.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U064E is present:

  • The check engine light remains illuminated constantly, signaling a persistent issue that requires diagnostics.
  • Drivers may experience engine hesitation or stalling during acceleration, which can be alarming and affect driving safety.
  • Fuel economy may decrease by 10-15%, indicating inefficient communication between engine components, leading to poor performance.
  • Unusual transmission shifting patterns may occur, such as hard shifts or delays in engagement, affecting overall drivability.
  • Electrical components, like the radio or dashboard lights, may flicker or behave erratically when this code is present.

Possible Causes

Most common causes of U064E (ordered by frequency):

  1. The most common cause of DTC U064E is a faulty wiring harness or loose connections, which occurs in approximately 60% of cases. This can arise from wear and tear or improper installation during repairs.
  2. Another significant cause is a malfunctioning control module, such as the PCM or TCU, with an estimated likelihood of 25%. Diagnosing this requires specialized tools to check module functions.
  3. Corroded connectors can also lead to communication errors, and while it's less common, about 10% of cases can be attributed to this. Regular inspections of connectors can help prevent this.
  4. In rare cases, issues related to the vehicle's battery, such as low voltage or a failing battery, can trigger this code. Maintaining a healthy battery is crucial for overall vehicle performance.
  5. A defective or outdated software in the vehicle’s modules could lead to communication failures, which is less common but can happen, particularly in older vehicles.
