C0044 is an OBD-II diagnostic trouble code meaning “Brake Pressure Sensor 'A' Circuit.” This code points to a fault in brake pressure sensor 'A', which the ABS/stability module uses to measure hydraulic pressure in the brake system. The module detected an out-of-range, shorted, or open signal from this sensor, so it can no longer trust the pressure reading. Because stability control and ABS modulation depend on accurate pressure data, those systems may be disabled. Drivers may notice ABS/traction/brake warning lights and, in some cases, a softer or less responsive pedal feel. This code is most commonly reported on 2014-2022 Land Rover Range Rover Sport, with repair costs ranging from $600 to $1,800.
