What Does The Hyundai C1237 Code Mean?

The pressure sensor signals are read via AID converter. Each unfiltered input signal voltage is monitored to be in the range of 0.2V < input signal voltage < 4.8V. There is no restriction of the pressure output voltage if the specified operating range is reached or exceeded. The signal can therefore reach into a fault area without any fault being present in the sensor. A failure is detected if the output signal stays in one of the fault areas longer than the monitoring time.
