U1024 Code Nissan Meaning

The U1024 code in Nissan vehicles refers to a problem with the VVEL (Variable Valve Event and Lift) control module’s CAN (Controller Area Network) communication.

This code indicates that there is a communication issue between the VVEL control module and other modules in the vehicle’s network. This can cause various issues, such as engine misfires, reduced power, and poor fuel economy.

Signs and Symptoms of U1024 Code in Nissan

Here are some of the signs and symptoms that you may experience if your Nissan has a U1024 code:

• Check engine light: The most common symptom of the U1024 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine or emissions system.
• Reduced engine performance: If the VVEL control module is not communicating properly with the engine control module, it can cause a reduction in engine performance. You may notice that your Nissan is not accelerating as quickly as it used to or that it feels sluggish when you press the gas pedal.
• Engine misfires: A misfire occurs when one or more cylinders in the engine fail to ignite properly. This can be caused by a variety of issues, including a problem with the VVEL control module’s communication. If you experience engine misfires, you may notice a rough idle or a lack of power when driving.
• Stalling: In some cases, the U1024 code can cause the engine to stall or shut off completely. This can be dangerous if it happens while you are driving, as it can cause a loss of control over the vehicle.
• Poor fuel economy: If the engine is not running efficiently due to a problem with the VVEL control module, it can cause a decrease in fuel economy. You may notice that you are getting fewer miles per gallon than you used to.

Possible Causes of U1024 Code in Nissan

Here are some possible causes of the U1024 code:

• Faulty VVEL control module: The VVEL control module may be faulty, causing it to fail to communicate with other modules in the vehicle. This can be due to a hardware or software issue.
• Wiring issues: There may be a problem with the wiring between the VVEL control module and other modules in the vehicle. This can be due to damaged or corroded wiring, loose connections, or other issues.
• Failed CAN bus: The CAN bus, which is responsible for communication between modules in the vehicle, may have failed. This can be due to a hardware or software issue.
• Failed module: Another module in the vehicle may have failed, causing it to stop communicating with the VVEL control module. This can be due to a hardware or software issue.
• Software issues: There may be a problem with the software in the VVEL control module or other modules in the vehicle. This can be due to a programming error, a software bug, or other issues.

• Check the wiring and connectors: Start by inspecting the wiring and connectors in the CAN network. Look for any signs of damage, corrosion, or loose connections. If you find any issues, repair or replace the affected components.
• Check other modules: If the wiring and connectors appear to be in good condition, check the other modules in the network. A problem with another module could be causing the communication issue with the VVEL control module.
• Replace the VVEL control module: If you have ruled out other potential causes, the VVEL control module itself may be faulty. In this case, you will need to replace the module with a new one.
• Reset the code: Once you have fixed the underlying issue, you will need to reset the U1024 code using an OBD-II scanner. This will clear the code from the vehicle’s memory and turn off the check engine light.
