Preconditions
The monitor will not run unless:
MIL is OFF.
ECT (Coolant Temp) is 176F (80C) or greater.
IAT (Intake Air) is 14F (±10C) or greater.*
* For 2002 MY and later vehicles: The readiness test can be completed in cold ambient conditions
(less than 14F / ±10C), if the drive pattern is repeated a second time after cycling the ignition OFF.
Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
Note the IAT (Intake Air) value during engine startup. The driving time must be adjusted
during step ªaº based upon IAT (Intake Air) value at startup.
a. Drive the vehicle at 40 ± 55 mph (64 ± 88 km/h) for the time described below:
If IAT (Intake Air) was less than 50F (10C) when the engine was started,
drive for 7 minutes.
If IAT (Intake Air) was greater than 50F (10C) when the engine was started,
drive for 3 minutes.
b. Drive the vehicle allowing speed to fluctuate between 35 ± 45 mph (56 ± 72 km/h)
for about 16 minutes.
NOTE:
Drive with smooth throttle operation.
Avoid sudden acceleration.
Avoid sudden deceleration as much as possible with the throttle fully closed.
If readiness status does not switch to ªcomplete,º ensure preconditions are met, turn the
ignition OFF, then repeat steps ªaº and ªb.º
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).
Pending Codes are available from the DTC Info Menu in Enhanced OBDII.
Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.
Once a second trip is completed, a current DTC will be stored. Readiness

a. Start the engine and allow it to idle for 2 minutes or more.
b. Drive the vehicle at 25 mph (40 km/h) or more for at least 50 seconds.
Be sure engine speed remains above 900 rpm.
c. Stop the vehicle and allow the engine to idle for 40 seconds or more.
