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

Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.
