DTC P0300 / P0301 / P0302 / P0303 / P0304: Random Misfire Detected / Cylinder 1 / Cylinder 2 /
Cylinder 3 / Cylinder 4 Misfire Detected
S6RW0D1104039
System Description
ECM measures the angle of the crankshaft based on the pulse signal from the CKP sensor and CMP sensor for each
cylinder. If it detects a large change in the angle speed of the crankshaft, it concludes occurrence of a misfire. When
the number of misfire is counted by ECM beyond the DTC detecting condition, it determines the cylinder where the
misfire occurred and output it as DTC.

System Description
The CMP sensor located on the transmission side of cylinder head (VVT model) or timing chain cover (non-VVT
model) consists of the signal generator (magnetic sensor) and signal rotor (intake camshaft portion (VVT model) or
exhaust camshaft timing sprocket (non-VVT model)).
The signal generator generates reference signal through slits in the slit plate which turns together with the camshaft.
Reference signal
The CMP sensor generates 6 pulses of signals each of which has a different waveform length while the camshaft
makes one full rotation. Refer to “Inspection of ECM and Its Circuits”.
Based on these signals, ECM judges which cylinder piston is in the compression stroke and the engine speed.
