About C1761

C1761 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 C1761 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1761 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 C1761 is a Ford air suspension code indicating the suspension control module has detected an open circuit on the rear height sensor signal line. The rear height sensor reports the distance between the body and the rear axle so the module can fill or vent the rear air springs to maintain ride height as load changes. When the module sees no usable signal, caused by a break in the wiring, a disconnected or corroded connector, or a failed sensor element, this code sets. With the code present, automatic rear leveling stops, the air suspension warning is displayed, and the rear of the vehicle ma...
