4 Causes of Honda Vsa Solenoid Valve Malfunction

All modern Honda vehicles incorporate the Vehicle Stability Assist (VSA) feature. 

It is an electronic system that improves vehicle handling even driving in bad conditions. 

A VSA system can get damaged for many reasons, and your ability to understand and deal with them is a crucial skill.

This article will examine the meaning of a Honda Vsa Solenoid Valve Malfunction, its symptoms, and how to fix it. 

Meaning of Honda Vsa Solenoid Malfunction 

If you have a problem starting your Honda VSA, you may face a malfunctioning Solenoid.

With this component working correctly, you cannot start your vehicle. 

Before we move on, we need to understand what VSA is in your Honda. VSA stands for Vehicle Stability Assist. 

It is responsible for ensuring proper handling when driving. Cornering when driving could be tricky and can lead to accidents. 

Vehicle Stability Assistant uses sensors that keep track of the vehicle’s movement. Once the vehicle starts losing control, skidding, and more, the sensor alerts the system. 

The VSA system reduces the throttle and appropriately brakes to restore handling. 

With your VSA working correctly, you can avoid difficulty maneuvering your vehicle in difficult areas.  

When the ECM encounters problems with communicating with the VSA system, a related code to a Vsa Solenoid Valve Malfunction might arise.

Also, other damaged parts of the ABS and wiring issues might cause these problems. 

It would be best to have a proper diagnosis when you start having problems with your vehicles, ABS, and handling.   

Symptoms of Honda Vsa Solenoid Valve Malfunction

Honda Vsa Solenoid Valve Malfunction comes with a series of signs which can easily be traced to the issue. One prominent sign is the ABS and brake warning light.

The following are the symptoms of Vsa Solenoid Valve Malfunction:

1. ABS and Brake light triggered 

2. Triggered engine light 

3. Traction control light triggered 

4. You will get any of these codes when you run a proper diagnostic. 

  1. DTC 121-11
  2. DTC 122-11
  3. DTC 123-11
  4. DTC 124-11

Other noticeable symptoms of a Honda Vsa Solenoid Valve Malfunction when driving may include the following. 

1. Bad handling, especially when cornering, braking, or speeding. 

2. Vibration in the steering wheel when cornering when slight;y speeding

3. Disturbing sound made by the VSA system when driving or cornering 

4. Slower braking and acceleration than normal 

5. Vehicle might lose traction or skid unexpectedly 

6. Decrease in the power steering 

When you notice all these symptoms, it is advisable to have your vehicle fixed before driving again. Symptoms like this could cause serious road accidents, especially when speeding.  

Causes of Honda Vsa Solenoid Malfunction

A significant cause of your Honda’s Vsa Solenoid Valve Malfunction could be traced to the ABS control module. 

Damaged ABS control modules will trigger the code and also warning lights.  

Other factors could cause a Vsa Solenoid Valve Malfunction. They include the following.

1. Damaged wiring problems 

2. Faulty control ABS module  

3. Damaged electronic sensors 

4. ECU software failure

Fixes for Honda Vsa Solenoid Valve Malfunction

When it comes to mechanical fixes like the Vsa Solenoid Valve Malfunction, you need to do it according to its causes. 

Many factors could cause a Vsa Solenoid Valve Malfunction, and we need a proper diagnosis. 

Once you have gotten the proper diagnosis and cause, then you can go ahead and fix it. 

The following are ways you could fix a Vsa Solenoid Valve Malfunction in your Honda car. 

1. Fix the wiring problem 

The ECM constantly communicates between various vehicle parts, including the VSA system. When communication is lost, then the system begins to fail or malfunction.

A significant cause of loss of connection between the ECM and VSA system is a wiring issue. Once the connection is corroded or disconnected, a Vsa Solenoid Valve Malfunction will arise. 

To solve this, you need to trace the VSA system wiring and check for corrosion or other forms of damage. If you find any, ensure to have the wire replaced.  

2. Faulty control ABS module

The VSA and the ABS are generally managed and controlled by some of the same components in your Honda. It is why when something is wrong with the ABS module, it also affects the VSA. 

By changing a damaged ABS module, you can eliminate a Faulty control ABS module and all its symptoms. 

Before changing the ABS module, use your OBD scanner to clear all errors and warning lights. 

If, after doing that, the warning light and error codes remain that you should check the module. 

3. Damaged electronic sensors

The VSA system uses electronic sensors to track the vehicle’s movement. These sensors are located on the wheels of the vehicle. 

When the sensors get damaged, the VSA cannot function as it should, leading to a Vsa Solenoid Valve Malfunction. 

When you are faced with this issue, first examine the wiring connection of the sensors. In some cases, people change the sensor and still have the same problem. It is because the issue is from the wires.

Once you are sure that the problem is from a damaged sensor, you can replace it. 

4. ECU software failure

The ECU is the center of the function of the VSA and other essential vehicle components. When the ECU runs into software issues, it sends out false errors and warnings. 

You will have to get your ECU reprogrammed to solve its software issue. 

Any professional mechanic will be able to do this for you. They will also be able to confirm if the ECU is completely damaged and should be replaced.  

Final Thoughts!

We have been able to look into the meaning, causes, and solutions to a Honda Vsa Solenoid Valve Malfunction. 

It would be best if you diagnosed properly before fixing the Vsa Solenoid Valve Malfunction issue. You can start by using an OBD scanner to scan for related codes. 

In addition, if you correctly follow our guide, you can resolve your Honda’s Vsa Solenoid Valve Malfunction. 

If the error continues, you may need to visit a professional to help with the fix.
