Detailed Description of Error C0055
OBDII error code C0055 is a fault code that is related to the Steering Wheel Position Sensor (SWPS) ''Signal D'' (Subfault). This code is typically set by the vehicle''s onboard computer (OBD-II) when it detects a problem with the signal from the SWPS. The SWPS is used by the vehicle''s Electronic Stability Control (ESC) system to monitor the steering wheel position and make adjustments to improve vehicle stability and safety.
The ''Signal D'' designation indicates that the fault is related to a specific signal or circuit within the SWPS. A ''Subfault'' designation indicates that the fault is a secondary or subsidiary fault, rather than a primary fault. In other words, the fault is related to a specific aspect of the SWPS operation, rather than a complete failure of the sensor itself.
When error code C0055 is set, the vehicle''s ESC system may enter a ''Limp Mode'' or ''Default Mode'', which can result in reduced vehicle performance and safety. The code may also be accompanied by other symptoms, such as a warning light on the dashboard or a loss of steering wheel control.
