Suspension System Height Sensor Out of Range
The suspension system height sensor signal is out of the normal range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer is seeing that the suspension height sensor is sending back values that are too high or too low, meaning the vehicle's height is not what it should be for proper handling and ride quality.
What the computer is actually seeing
The suspension control module expects the sensor output to be within a certain voltage range (typically between 0.5V and 4.5V), corresponding to the correct vehicle height. If the voltage is below 0.5V or above 4.5V, it triggers this fault code.
What a healthy reading looks like
Check for a sensor output around mid-range (about 2.5V) when the vehicle is at the normal height; adjust values according to the specific suspension system specs.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors at the height sensor for damage or corrosion. Repair as needed; if connections are good, move to step 2.
- 22. Check the height sensor output voltage with a multimeter while the vehicle is at the normal ride height. You should see around 2.5V. If it's out of range, replace the sensor as it's likely faulty; if voltage is good, move to step 3.
- 33. Examine the suspension components for any visible damage or misalignment that could affect the sensor reading. Fix any issues found; if all looks good, move to step 4.
- 44. Consider recalibrating the suspension system with a scanner if applicable. After calibration, clear the code and test drive the vehicle to see if the code returns.
Common causes
- Faulty height sensor
- Wiring issues (shorts or open circuits)
- Bent or damaged suspension components
- Improper installation or calibration
- Moisture or corrosion in connectors
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code active?
While the vehicle may still be drivable, handling can be affected and you should fix it soon to avoid potential safety issues.
Will this code come back after clearing?
If the underlying issue isn't resolved, yes, it will likely return after clearing.
Why does this code sometimes accompany other suspension-related codes?
It's common for multiple suspension codes to trigger if there are problems with the height sensor or wiring affecting the whole system.
