C0044 on Land Rover
Brake Pressure Sensor 'A' Circuit
C0044 on Land Rover vehicles indicates brake pressure sensor 'a' circuit. Au7o has documented this code across 1 Land Rover model — most commonly on Range Rover Sport. 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. Typical repair costs on Land Rover range from $600 to $1,800, depending on the specific model and root cause.
Common Causes of C0044
- •Faulty brake pressure sensor
- •Damaged sensor wiring or connector
- •Open or short in the pressure sensor circuit
- •Corrosion at the sensor or module connector
- •Loss of communication with the ABS/EBCM
- •Internal fault in the ABS hydraulic unit
- •Low brake fluid or air affecting pressure readings
C0044 on Land Rover by Model
Land Rover Range Rover Sport(1 issue)
- Electric Parking Brake Actuator Failure2014-2022
The electric parking brake (EPB) actuator motors on the L494 Range Rover Sport fail prematurely, leaving the parking brake either stuck engaged or unable to hold the vehicle. The actuator motors are exposed to road salt and moisture, causing internal corrosion and motor burnout. The EPB system also integrates with the auto-hold hill start feature, so failures affect drivability.
