The P0103 trouble code indicates that the Mass Air Flow (MAF) sensor is sending a higher-than-expected voltage signal to the engine control module (ECM).
The P0102 trouble code indicates that the Mass Air Flow (MAF) sensor is sending a lower-than-expected signal voltage to the engine control module (ECM).
The MAF sensor measures the amount of air entering the engine. The ECM uses this information to calculate the correct fuel injection amount.
The P0088 trouble code indicates that the fuel pressure in the fuel rail is higher than the engine control module (ECM) expects.
The P0193 trouble code indicates that the Fuel Rail Pressure Sensor (FRP) is sending a higher-than-expected voltage signal to the engine control module (ECM).
The P0192 trouble code indicates that the Fuel Rail Pressure Sensor (FRP) is sending a lower-than-expected voltage signal to the engine control module (ECM).
The P0190 trouble code indicates a malfunction in the Fuel Rail Pressure Sensor (FRP) circuit.
The fuel rail pressure sensor measures the fuel pressure inside the fuel rail and sends this information to the engine control module (ECM).
The P0118 trouble code indicates that the Engine Coolant Temperature (ECT) sensor is sending a higher-than-expected voltage signal to the engine control module (ECM).
The P0115 trouble code indicates a malfunction in the Engine Coolant Temperature (ECT) sensor circuit.
The ECT sensor measures the temperature of the engine coolant and sends this information to the engine control module (ECM).
The P0113 trouble code indicates that the Intake Air Temperature (IAT) sensor is sending a signal that is higher than the expected voltage range.
The IAT sensor measures the temperature of the air entering the engine. This information helps the engine control module (ECM) adjust the fuel mixture and ignition timing.
