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 16, 2020 P0307 Code: Cylinder #7 Misfire DetectedRemember that the efficient burning of air and fuel is essential to engine operation. Without the proper combustion of the air/fuel mixture, the engine won’t run properly or won’t run at all.
September 16, 2020 P0170 Code: Fuel Trim (Bank 1)Note: Code P0170 is a generic code defined by the Society of Automotive Engineers (SAE). The vehicle’s manufacturer may set a different definition for the code.
If the computer cannot properly adjust the air-fuel mix, it will log the diagnostic trouble code P0170.
What are the Possible Causes of the P0170 Code?
September 15, 2020 P0191 Code: Fuel Rail Pressure Sensor “A” Circuit Range/PerformanceTo prevent both lean and rich mixtures from compromising the engine’s performance, the PCM regulates the output of the fuel injectors to add the right amount of fuel to the engine. On many modern vehicles, the PCM depends on the fuel rail pressure sensor to send it a constant stream September 15, 2020 P0201 Code: Cylinder 1 Injector Circuit/OpenIdeally, when the injector is switched on, the expected voltage should be low or close to zero. When the injector is off, there should be an increase in voltage. If the voltage readings are not what is expected, the PCM may trigger code P0201. Aside from that, this code may
