P1372 — Vehicle Speed Sensor out of range

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Hyundai

About P1372

P1372 is a manufacturer-specific powertrain diagnostic trouble code recorded for Hyundai vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1372 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1372 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 vehicle speed sensor (VSS) provides the Engine Control Module and other systems with road speed, used for idle control, fuel control, transmission shift scheduling, and the speedometer. On many Hyundai and Kia models the signal comes from a sensor on the transmission output shaft, while on others it is derived from the ABS wheel speed sensors over the network. DTC P1372 is set when the ECM receives a vehicle speed signal that is out of its expected range or is implausible compared with engine speed and load. Symptoms can include a faulty or erratic speedometer, harsh or incorrect gear shif...
