Frequently Asked Questions

Can I replace the ride height sensor myself?

Yes, on most vehicles the sensor is accessible at the suspension and can be replaced with basic hand tools. The sensor may need to be calibrated with a scan tool after installation.

Why is the compressor running constantly?

If the ride height sensor sends an incorrect low reading, the system thinks the vehicle is too low and keeps running the compressor trying to raise it. This can burn out the compressor.

Is the ride height sensor the same as the headlight leveling sensor?

Some vehicles use the same sensors for both functions, while others have separate sensors. The headlight leveling system typically uses the rear ride height sensors.
