About C1A58

C1A58 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 C1A58 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.

C1A58 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 Tyre Pressure Monitoring System (TPMS) module monitors identification and configuration data for each wheel position. DTC C1A58 with subcode :51 is set when the TPMS module does not have valid programmed data for the front right wheel module, indicating that the sensor or wheel module has not been learned, has been replaced without completing the programming procedure, or the stored identification data is missing or invalid. This prevents correct tyre pressure monitoring for the affected wheel position.
