September 22, 2020 P0004 Code: Fuel Volume Regulator Control Circuit HighDiagnostic trouble code (DTC) P0004 code stands for “Fuel Volume Regulator Control Circuit High.” This code indicates that the vehicle’s computer (also known as the powertrain control module or the PCM) has detected that the electrical reading in the fuel volume regulator control circuit is above the expected value. As September 22, 2020 P0003 Code: Fuel Volume Regulator Control Circuit LowDiagnostic trouble code (DTC) P0003 stands for “Fuel Volume Regulator Control Circuit Low.” Although rare, it’s not impossible for your scan tool to retrieve this code. The P0003 code is commonly seen on common rail diesel (CRD) engines, and gasoline direct injection (GDI) equipped vehicles.
September 23, 2020 P0050 Code: HO2S Heater Control Circuit Bank 2 Sensor 1Oxygen sensors measure the amount of oxygen in the exhaust. They send data to the vehicle’s PCM, which adjusts the air-fuel ratio accordingly. A conventional oxygen sensor will only send a voltage signal once its tip reaches a temperature of about 527°F.
