About C1952

C1952 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1952 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1952 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 measures how quickly the vehicle is rotating about its vertical axis and reports it to the stability control module, which compares it against steering angle, lateral acceleration, and wheel speed to detect oversteer and understeer. It is often packaged with the lateral g sensor in a single cluster and may report over a local data bus. DTC C1952 sets when the module detects an open circuit in the yaw rate sensor circuit, losing the signal, supply, or return path. When this code is set the stability and traction control functions are usually disabled and the warning lamps il...
