(a) Preconditions
The monitor will not run unless:
MIL is OFF
Fuel level is approximately 1/2 to 3/4
Altitude is 7,800 feet (2,400 m) or less
Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)
Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)
Cold Soak Procedure has been completed
Before starting the engine, the difference between ECT and IAT must be less than 7°C (13°F)
HINT:
Examples:
Scenario 1
ECT = 24°C (75°F)
IAT = 16°C (60°F)
Difference between ECT and IAT is 8°C (15°F)
" The monitor will not run because difference between ECT and IAT is higher than 7°C (13°F)
Scenario 2
ECT = 21°C (70°F)
IAT = 20°C (68°F)
Difference between ECT and IAT is 1°C (2°F)
" The monitor will run because difference between ECT and IAT is less than 7°C (13°F)
The readiness test can be completed in cold ambient conditions (less than 40°F / 4.4°C) and/or at
high altitudes (more than 7,800 feet / 2,400 m) if the drive pattern is repeated a second time after cycl-
ing the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to DLC3 to check monitor status and preconditions (refer to (a)).
(2) Release pressure in fuel tank by removing the fuel tank cap and then reinstall it.
(3) Start the engine and allow it to idle until ECT becomes 75°C (167°F) or higher.
(4) Run the engine at 3,000 rpm for approximately 10 seconds.
(5) Allow the engine to idle with the A/C ON (to create slight load) for 15 to 50 minutes.
NOTICE:
If the vehicle is not equipped with A/C, put a slight load on the engine by doing the following :
Securely set the parking brake.
Block the drive wheels with wheel chocks.
Allow the vehicle to idle in drive for 15 to 50 minutes.

5. AIR±FUEL RATIO (A/F) AND OXYGEN SENSOR (HO2) MONITOR (ACTIVE AIR±FUEL RATIO
CONTROL TYPE)
(a) Preconditions
The monitor will not run unless:
2 minutes or more have elapsed since the engine was started.
The Engine Coolant Temperature (ECT) is 75C (167F) or higher.
Air±fuel ratio feedback control is performed.
Fuel±cut control is performed for 8 seconds or more.
(b) Drive Pattern
(1) Connect the hand±held tester to DLC3.
(2) Turn the ignition switch to ON.
(3) Clear DTCs (see page DI±43).
(4) Start the engine, and warm it up until the ECT reaches 75C (167F) or higher.
(5) Drive the vehicle at 40 mph (64 km/h) or more for at least 10 minutes.
(6) Change the transmission to 2nd gear.
(7) Accelerate the vehicle to 30 mph (48 km/h) or more by depressing the accelerator pedal for at
least 10 seconds.
(8) Soon after performing step (8) above, release the accelerator pedal for at least 4 seconds without
depressing the brake pedal, in order to execute fuel±cut control.
(9) Stop the vehicle and allow the engine to idle for 10 seconds or more.
(10) Allow the vehicle to decelerate until the vehicle speed declines to less than 6 mph (10 km/h).
(11) Repeat steps from (8) through (10) above at least 3 times in one driving cycle.
(c) Monitor Status
(1) Check the Readiness Monitor status displayed on the tester.
(2) If the status does not switch to COMPL (complete), make sure that the preconditions have been
met, and then perform steps from (5) through (11) in Drive Pattern above.
