Code P2159 KIA Description
The PCM evaluates engine speed and mass air flow if there is no vehicle speed signal. This evaluation of both values will detect open circuit or short circuit errors on the wheel speed sensor. The PCM sets DTC P2159 if there is no vehicle speed signal from the wheel speed sensor while both engine speed and mass air flow are higher than the predetermined threshold during the predetermined time.
