C1279 — Yaw Rate Sensor circuit Failure

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

About C1279

C1279 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 C1279 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.

C1279 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

The yaw rate sensor is part of the vehicle stability control system and reports the rate of rotation of the vehicle about its vertical axis to the ABS or chassis control module. It is typically a MEMS based sensor mounted near the centre of gravity on the floor or tunnel, often combined with the lateral acceleration sensor in a single module. DTC C1279 sets when the controlling module detects a complete loss of yaw rate signal, an out of range value, or no communication from the sensor on its private signal or CAN bus connection. When this code is active, stability control, traction control, r...
