General Information

Component Location





General Description

The wheel speed sensor is the essential component that the ECM uses to calculate vehicle speed. This wheel speed sensor is the active hall-sensor type and good at temperature and noise characteristic. Digital wave is produced as tone wheel rotate according as hall sensor principle. Frequency of duty wave is changed in proportion to rotation of tone wheel and ECM gets vehicle speed through ABS/ESP control unit or the wheel speed sensor (In case of non-ABS/ESP vehicle).

DTC Description

If the vehicle speed signal is below 1.0 Km/h during 2 sec under enable conditions, ECM sets P0501.
