September 16, 2020 P0307 Code: Cylinder #7 Misfire DetectedDiagnostic trouble code (DTC) P0307 stands for “Cylinder #7 Misfire Detected.” This code is logged when the powertrain control module (PCM) perceives that your vehicle’s cylinder #7 may be misfiring. This indicates that incomplete combustion is happening inside the cylinder.
September 16, 2020 P0355 Code: Ignition Coil “E” Primary/Secondary CircuitDiagnostic trouble code (DTC) P0355 stands for “Ignition Coil “E” Primary/Secondary Circuit.” It indicates that the powertrain control module (PCM) detected a problem in either the primary (computer side) or the secondary (spark plug side) #5 ignition coil “E” circuit.
September 16, 2020 P0170 Code: Fuel Trim (Bank 1)The stoichiometric mixture best suited for burning is 14.7 parts air to 1 part fuel. If the mixture contains excessive amounts of air, the PCM will add more fuel to balance out the lean mixture. Conversely, too much fuel leads to a rich mixture, and the computer compensates accordingly.
September 15, 2020 P0191 Code: Fuel Rail Pressure Sensor “A” Circuit Range/PerformanceToo little fuel will reduce the engine’s output when conditions demand all the power it can get. Conversely, adding more fuel than the engine could combust will waste fuel and raise emission levels in the engine exhaust, potentially causing damage to the catalytic converter.
September 15, 2020 P0201 Code: Cylinder 1 Injector Circuit/OpenNote: The definition of Code P0201 may vary depending on the vehicle manufacturer. It is best to consult your trusted repair manual or repair database for the exact code definition.
Fuel Injector Operation
September 15, 2020 P0001 Code: Fuel Volume Regulator Control Circuit/OpenAlthough P0001 is a generic code, it can pop up on various makes and models. This code indicates that your vehicle’s primary computer or PCM has detected a potential open in the fuel volume control valve (FVCV) circuit.
