About C1752

C1752 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 C1752 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; 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.

C1752 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

On many Ford systems the ABS or speed control module receives the raw vehicle speed signal and rebroadcasts it as a buffered square wave output to consumers such as the PCM, instrument cluster, and speed control servo. DTC C1752 is set when the module finds the vehicle speed sensor number 1 output circuit held at ground while it attempts to drive the signal, indicating the output wire is shorted to ground or to a grounded circuit. The raw wheel or transmission speed sensor is not the cause; the fault lies in the output wiring, a connector, or one of the consumer circuits clamping the line low....
