Min.: 0, Max.: 255

Engine speed for first misfire range/

Min.: 0 rpm, Max.: 6375 rpm

Diagnostic Note:

• This is the average engine speed recorded when misfiring occurs.

• This value is closer to the actual conditions of the vehicle at the time the misfire occurred than the values of engine speed and engine load stored in the freeze frame data. When reproducing malfunction conditions, use this value as a reference.

Engine load for first misfire range/

Min.: 0 g/rev, Max.: 3.98 g/rev

Diagnostic Note:

• This is the average engine load recorded when misfiring occurs.

• This value is closer to the actual conditions of the vehicle at the time the misfire occurred than the values of engine speed and engine load stored in the freeze frame data. When reproducing malfunction conditions, use this value as a reference.

Misfire monitoring/

Min.: -128%, Max.: 127%

Diagnostic Note:

This is the misfire detection margin.

Misfire Margin = (Misfire detection threshold - maximum engine speed variation) / misfire detection threshold x 100%

When the variation in the engine speed is large and exceeds the misfire detection threshold, the misfire count starts. Misfire margin is a measure of how much the engine speed variation can increase with respect to the threshold before the engine is determined to be misfiring.

A large value means there is a large margin for the engine speed to vary before the engine is determined to be misfiring.

Example:

When the engine is not determined to be misfiring, Misfire Margin = 52%.

When the engine is determined to be misfiring, Misfire Margin = -128 to 0%.
