C1763 — Air Suspension Rear Height Sensor High (SE) Signal Circuit Short To Ground

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Ford

About C1763

C1763 is a manufacturer-specific chassis diagnostic trouble code recorded for Ford vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1763 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; a signal or supply voltage higher than the expected operating range; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1763 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC C1763 is a Ford specific chassis code relating to the rear height sensor circuit in the four wheel air suspension system used on vehicles such as the Expedition and Lincoln Navigator. The rear height sensor is a potentiometer style sensor mounted between the rear axle and the frame, and it returns a variable voltage signal that tells the air suspension control module the current rear ride height. The module sets C1763 when it detects the rear height sensor signal circuit pulled low, indicating a short to ground in the signal wiring or within the sensor itself. When this code is set the mod...
