C1233 FORD, LINCOLN, MAZDA, MERCURY: LEFT FRONT WHEEL SPEED SENSOR INPUT SIGNAL MISSING
Also known as ABS Sensors, Wheel Speed Sensors have the function of measuring the rotational speed of the vehicle’s wheels while the vehicle is in motion. One of the most important reasons for performing this action is that thanks to this data, the ABS system modulates the braking force to the individual wheels and thus prevents the wheels from locking up under aggressive braking.
The wheel speed sensors produce magnetic signals once the teeth of a slip ring pass in front of the sensor. These signals are received and converted by the PCM into electrical signals, which are used to control the frequency of the signals that are directly related to the rotational speed of each wheel.
C1233 OBDII fault code is stored on Ford, Lincoln, Mercury, and Mazda vehicles when the PCM detects a missing input signal from the Left Front Wheel Speed Sensor. The Jaguar vehicle manufacturer defines this code similarly, but with some differences, although the symptoms, causes, and diagnosis are largely identical.
C1233 OBD2 diagnostic code is set by the following:
