A ride height sensor is a device that is used in vehicles to monitor the height of the vehicle's suspension system. The ride height sensor measures the distance between the chassis of the vehicle and the ground. Ride height sensors are usually located on the suspension system, typically on the control arm or on the frame of the vehicle. It is used to ensure that the suspension system is functioning properly. The sensors send signals to the vehicle's computer, which then adjusts the suspension system accordingly.

Symptoms of a bad ride height sensor

As an important part of a vehicle's suspension system, ride height level sensor malfunction can cause a series of problems that affect the vehicle’s overall performance and safety of the ride. The following symptoms are telling that your ride height may be bad:

The suspension system is too high or too low. One of the most common signs of a bad ride height sensor is that the suspension system is either too high or too low. This can make it difficult to handle the vehicle and can even cause damage to other parts of the vehicle over time.
Your Vehicle rides rough. When the ride height level sensor is not functioning properly, the suspension system is not able to adjust to changes in the road surface. As a result, the vehicle may ride rough or have a bumpy ride.
The tires of your vehicle wear unevenly. The abnormal working of the ride height sensor can cause uneven wear on the tires. This is because the suspension system is not able to maintain proper alignment, which can lead to excessive wear on one side of the tire.
A failing ride height level sensor can also be told by the warning lights on the dashboard. Modern vehicles have warning lights on the dashboard that will illuminate if there is a problem with the suspension system or ride height sensor.
When the vehicle leans to one side, that is, one side of the vehicle sits lower than the other, you should consider the ride height sensor problem. This issue will be difficult to handle, so if you detect any problems, have your vehicle inspected.

Can I adjust the ride height sensor?

Generally speaking, ride height sensors are used in vehicles with air suspension systems which are responsible for measuring the distance between the ground and the vehicle's chassis. So the process for adjusting the ride height sensor will depend on the specific make and model of the vehicle. But you can always refer to the following procedure:

Choose and determine the right ride height level sensor you need before locating. Depending on the type of sensor and the vehicle's suspension system, you may need to adjust the sensor's mounting position or the linkage that connects it to the suspension components. Some ride height sensors may have an adjustment screw that can be turned to fine-tune the sensor's output. And then, the testing step always matters. Once you have adjusted the ride height sensor, test the vehicle to ensure that it is at the correct ride height. This may involve driving the vehicle or using a diagnostic tool to check the sensor's output.

Improperly adjusted ride height sensors can affect the vehicle's handling, stability, and ride comfort, so it's important to ensure that the sensor is properly calibrated. You are advised to leave the replacement work to a qualified technician.
