What is the cause of the Mercedes-Benz C1144 fault code?
1 Answers
Mercedes-Benz C1144 fault code indicates a malfunction in the pressure sensor. Symptoms of sensor failure: Common symptoms of a faulty intake pressure sensor in a vehicle include: open or short circuits in the internal wiring of the sensor; the sensor output signal fails to change with variations in intake manifold vacuum; the output signal voltage is excessively high or low, deviating from the normal range. Pressure sensor: The intake pressure sensor measures the engine's air intake volume to control the basic fuel injection quantity. It detects the absolute pressure in the intake manifold behind the throttle valve. Based on engine speed and load, it monitors changes in the manifold's absolute pressure and converts this into a signal voltage sent to the Engine Control Unit (ECU). The ECU uses this signal voltage to determine the basic fuel injection quantity.
