Code C1148 Mazda Description

The C1148 code for Mazda vehicles indicates an issue with the Right Front ABS Wheel Speed Sensor or Sensor Rotor. The ABS (Anti-lock Braking System) Wheel Speed Sensor is responsible for monitoring the speed of each wheel and sending this information to the ABS control module. The Sensor Rotor is a toothed ring that the sensor reads to determine the wheel speed. When the ABS system detects a discrepancy between the speed of the wheels, it can trigger the C1148 code.
