C1724 — Air Suspension Height Sensor Power Circuit Failure

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

About C1724

C1724 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 C1724 is stored, the module has detected 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.

C1724 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 C1724 relates to the air suspension ride height sensor power supply circuit. The air suspension control module provides a regulated voltage feed to the ride height sensors, which report the distance between the chassis and the suspension so the module can maintain correct vehicle height by filling or venting the air springs. This code sets when the module detects a general failure of the height sensor power circuit, such as the supply voltage sitting outside its expected range, dropping out intermittently, or failing the module's internal output check. When C1724 is set, the module typical...
