P0503 is a diagnostic trouble code that stands for “Vehicle Speed Sensor Intermittent\/Erratic\/High.” It is a common error code for vehicles made since 1996. Read to know more about the P0503 error code.\u00a0<\/em><\/p>\n

P0503 is a generic trouble code, which means it applies to any vehicles manufactured from 1996 to the present. You’ll notice it, particularly in those equipped with an OBD-II system, such as those found in Cadillac, Chevrolet, GM, GMC, Saab, Subaru, and Volvo. Do keep in mind that troubleshooting and repairs differ from one to another.<\/span>\u00a0<\/span><\/p>\n

What is P0503? <\/span>\u00a0<\/span><\/h2>\n

The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makers) has identified an irregular, intermittent, or excessive voltage input signal from the VSS when error code P0503 is saved (vehicle speed sensor). The “A” in ‘Vehicle Speed Sensor A Intermittent’ refers to the primary VSS in a system made up of numerous vehicle speed sensors.<\/span>\u00a0<\/span><\/p>\n

Electromagnetic speed sensors are standard on most automobiles. A toothed reluctor ring wheel or gear attached to an axle, transmission\/transfer case output shaft, driving shaft, or differential gear is used in this form of sensor. The reluctor device spins with the shaft pins, connecting to the stationary electromagnetic sensor. <\/span>\u00a0<\/span><\/p>\n

When the reluctor passes very close to the sensor’s electromagnetic tip, the notches in the reluctor ring cause disruptions in the sensor circuit. The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makers) and other controllers receive combinations of these circuit completions and other disruptions as waveform patterns that represent voltage.<\/span>\u00a0<\/span><\/p>\n

The PCM uses data from one or more vehicle speed sensors to monitor the vehicle’s speed and compare it to inputs from the ABCM (antilock brake control module) or EBCM (electronic brake control module) (electronic brake control module). <\/span>\u00a0<\/span><\/p>\n

A secondary VSS input may be monitored using one or more wheel speed sensors in various vehicle makes and models, but the primary VSS input (A) is most often initiated by the transmission’s VSS. If the primary VSS detects intermittent, irregular, or high input voltage, the Check Engine light will illuminate, and the error code P0503 will be stored in the vehicle’s memory.<\/span>\u00a0<\/span><\/p>\n
