P0503 OBD Code Definition:
P0503 Vehicle Speed Sensor A Intermittent/Erratic/High
P0503 OBD Code Description:
OBD2 Code P0503 Definition:
The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.
