Misfire Monitor

OBD System Description - Misfire Monitor

System Description / Monitoring Procedure
ECM measures the angle speed 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 the ECM beyond the DTC detecting condition, it determines the cylinder where the misfire occurred and outputs it as DTC.
