What does DTC code p0301 stand for?
Diagnostic trouble code (DTC) P0301 stands for “Cylinder 1 Misfire Detected.” The code indicates that the powertrain control module (PCM) has counted enough misfire events on cylinder 1 to store the misfire code for that cylinder.
What is the DTC for cylinder 1 misfire?
The Diagnostic Trouble Codes (DTC) P0301 correspond to cylinders 1. When the ECM detects that one or more specific cylinders are misfiring, the DTC for the respective misfiring cylinder will set, and up to 2 of the corresponding fuel injectors are disabled for a minimum of 30 s.
Which is the first cylinder in the p0301 code?
Cylinder number 1 in code P0301 would refer to the first cylinder in the firing order as well as the forward cylinder on the crankshaft. For example, on a Ford V8, the cylinders are numbered 1 to 4 on the passenger side bank and 5-8 on the driver side bank, beginning at the front of the engine.
What does the p0301 code on Toyota Prius mean?

What is meaning of code p0301?
What Is the Code P0301? This code is a general onboard diagnostic (OBD) code for vehicles. It indicates that the cylinder no. 1 in the engine is experiencing a misfire. This means that the cylinder isn’t getting enough spark, which results in the misfiring condition.
What is the cause of a p0302 misfire detected code?
A misfire is just what it sounds like; a cylinder that is not firing as it should. The P0302 code is caused by a misfire on the number two cylinder. The Misfire monitor diagnostic is based on variation in crankshaft velocity. The PCM determines this information using the crankshaft position sensor and camshaft position sensor.
What cause misfire in 1 cylinder?
Lean misfire causes that only affect one cylinder include a dirty fuel injector , an open or shorted fuel injector , or a problem in the fuel injector driver circuit (wiring or PCM). Compression problems that may cause a misfire include a burned exhaust valve, bent intake or exhaust valve, or leaky head gasket.
What does the engine code p0301 mean?
A P0301 code means that the the car’s computer has detected that one of the engine’s cylinders is not firing properly. In this case it’s cylinder #1.
