I/M Monitors (Emissions)

Inspection / Maintenance Monitors provide a snapshot of the Emis-

sion System operations by indicating that the I/M Monitors are Ready

or Not Ready. For an I/M Monitor to be Ready, the vehicle must have

completed a drive cycle (been driven long enough under proper

conditions to have completed a drive cycle). A Monitor must be listed

as Ready to pass an emissions test. If an I/M Monitor is Not Ready,

it is because a drive cycle has not completed.

The Tool will indicate Ready (ok), Not Ready (inc), or Not Applicable

(n/a) for each I/M Monitor. The Tool supports the following I/M Moni-

for example, does not have an Oxygen Sensor Monitor. As a result,

there will be no Oxygen Sensor Monitor status for a diesel vehicle.
