September 22, 2020 P0004 Code: Fuel Volume Regulator Control Circuit HighModern vehicles are fitted with specialized fuel systems to enhance the efficiency of the combustion process. Common rail diesel (CRD) engines, in particular, have a high-pressure fuel pump that develops the necessary fuel pressure for the injectors. A computer-controlled fuel volume regulator controls fuel flow to the high pressure pump.
September 16, 2020 P0307 Code: Cylinder #7 Misfire DetectedAn engine misfire is a common drivability problem that car owners may experience at one point. Once your vehicle’s primary computer detects an engine misfire, it will most likely turn on the check engine light.
September 16, 2020 P0355 Code: Ignition Coil “E” Primary/Secondary CircuitThere are three things needed to start the combustion process in a gas-powered engine: an air/fuel mixture, compression, and an ignition source. The air intake system and the fuel delivery system are responsible for the air and the fuel, respectively. As for the ignition source, a vehicle relies on ignition September 16, 2020 P0170 Code: Fuel Trim (Bank 1)To ensure the air-fuel ratio of the mixture burns as efficiently as possible, the powertrain control module (PCM) tweaks the vehicle’s fuel trim over short and long periods. If the computer cannot properly adjust the air-fuel mix, it will log the diagnostic trouble code P0170.
What Does the P0170 Code Mean?
September 15, 2020 P0191 Code: Fuel Rail Pressure Sensor “A” Circuit Range/PerformanceThe fuel rail pressure sensor keeps the powertrain control module (PCM) aware of the pressure levels in the fuel rail, so that the computer knows how much fuel the engine needs. When the PCM receives an irrational signal from the fuel rail pressure sensor, the module logs the P0191 code.
What September 15, 2020 P0201 Code: Cylinder 1 Injector Circuit/OpenYour vehicle’s fuel injectors are just some of the many components that are crucial for engine operation. Without them, fuel cannot reach your engine cylinders, and there would not be enough fuel to keep your vehicle running. OBD-II code P0201 is a generic diagnostic trouble code that is supported in
