Description

Misfire detection is accomplished by monitoring the voltage of the spark plug with the spark plug voltage sensor which is

built into the ignition coil.

If misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and a

misfire DTC will be stored. Then, after the misfire has ceased, the MIL will come on and stay on whenever the ignition

switch is ON (II).

If misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and a misfire

DTC will be stored.

NOTE: If some of the DTCs listed below are stored at the same time as a misfire DTC, troubleshoot those DTCs first, then

troubleshoot the misfire DTC.
