GENERAL DESCRIPTION
BN:DTC P0301 CYLINDER 1 MISFIRE DETECTED
1. OUTLINE OF DIAGNOSIS
Detect the presence of misfire occurrence. (Revolution fluctuation method)
Monitoring Misfire which influences exhaust deterioration (1.5 times of FTP) and catalyst damage is made
obligatory by the law. Misfire affecting these two has three patterns below. Intermittent misfire (Different cyl-
inders misfire intermittently.):
•Intermittent misfire (The same cylinder misfires in random, or different cylinders misfire in random.): FTP
1.5 times misfire
•Every time misfire (The same cylinder misfires every time.): FTP 1.5 times misfire, Catalyst damage misfire
The following detecting methods are adopted for these detection.
1) Intermittent misfire: FTP 1.5 times misfire
•120° Interval Difference Method
•360° Interval Difference Method (whole range)
•720° Interval Difference Method (3,000 rpm or less)
2) Misfire every time: FTP 1.5 times misfire, Catalyst damage misfire
•360° Interval Difference Method
2. ENABLE CONDITIONS

3. GENERAL DRIVING CYCLE
•If conditions are met, detect misfire from idling to high rotation.
•Perform the diagnosis continuously.

GENERAL DESCRIPTION
4. DIAGNOSTIC METHOD
When a misfire occurs, the engine RPM will decreased and the crankshaft position speed will change. Cal-
culate the interval difference value (diagnostic value) from crankshaft position speed by the following formu-
la, and judge whether a misfire is occurring or not comparing the calculated result with judgment value.
Counting the number of misfires, if the misfire ratio is higher during 1000 rev. or 200 rev. Judge correspond-
ing cylinders as NG.
As shown in the following figure, pick a cylinder as the standard and name it omg 0. And the former crank-
shaft position speed is named omg 1, the second former crankshaft position speed is named omg 2, the third
is named omg 3, etc.
