DTC C1237: Pressure Sensor-Signal: DTC Detecting Condition

DTC DETECTING CONDITION

DTC No.	Detecting Condition	Possible Cause
C1237	[Noisy signal, offset, stick] If input signal is noisy, Which the gradient of the sensor signal is larger than 15bar over 25times in 2sec, ECU detect the failure. Outside an ABS/TCS/ESC control, And after normal operation of BLS, If the pressure sensor signal is higher than 20bar and BLS is low for 3sec, ECU detect the failure.	Open/Short in the pressure sensor circuit Faulty the pressure sensor Faulty installing of the pressure sensor Faulty HECU
