[Comment]Background
l Excessive engine misfire results in increased catal yst temperature.
l Severe misfire could cause catalyst damage.
l To prevent catalytic converter damage, the PCM moni tors engine misfire.
l The PCM monitors for misfire during most engine ope rating conditions.
lWhen a misfire is detected, the PCM stores a diagnostic trouble code and causes the to either flash or illuminate continuously during active misfire.
Range of Check
l MAP voltage is less than 1.60
l Engine speed is between 2200 and 2800 l Engine coolant temperature is greater than l Vehicle speed less than Set Condition
l 1000 Rev Misfire
The PCM detects misfire in more than 1.6% of the en gine cycles in a 1000 revolution
period.l 200 Rev MisfireThe PCM detects misfire in more than 15% of the eng ine cycles in a 200 revolution period.
