Ride Height Sensor Rear Right Circuit Malfunction
What does C0160 mean?
The C0160 code means the vehicle's onboard diagnostic system has detected: Ride Height Sensor Rear Right Circuit Malfunction. This is a moderate severity code.
Common Symptoms
- Suspension warning light on
- Rear right corner sitting low
- Vehicle leaning to one side
- Air suspension compressor cycling frequently
- Auto-leveling headlights not adjusting
Probable Causes (Ranked by Likelihood)
- Failed rear right ride height sensor Very High
- Broken sensor arm or linkage High
- Corroded sensor from road salt exposure Moderate
- Suspension module rear right input fault Low
Step-by-Step Diagnostic Procedure
-
Scan suspension module for DTCs
-
Read and compare all four ride height sensor values
-
Inspect rear right sensor physical condition
-
Check linkage connection and movement
-
Test sensor output voltage through travel range
Frequently Asked Questions
Can a worn air spring also cause this code?
A leaking air spring will cause the vehicle to sag on that corner, but the ride height sensor should still report correctly. However, the system may log additional codes if the sensor cannot keep up with rapid height changes.
Do I need a scan tool to calibrate after replacement?
Most vehicles require a scan tool to calibrate or initialize the new ride height sensor so the suspension module knows the correct zero point and range of the replacement sensor.
Is this related to the self-leveling rear suspension?
Yes. Vehicles with self-leveling rear suspension, whether air or electronically controlled, rely on ride height sensors to maintain proper vehicle height under varying loads.
