After a repair, check Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow Monitor
Confirmation described below.
1. KEY-OFF MONITOR CONFIRMATION
(a) Preconditions
The monitor will not run unless:
The vehicle has been driven for 10 minutes or more (in a city area or on a freeway)
The fuel tank is less than 90% full
The altitude is less than 2438 m (8000 ft.)
The Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)
The Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)
The vehicle remains stationary (the vehicle speed is 0 km/h [0 mph])
(b) Monitor Conditions
Allow the engine to idle for at least 5 minutes.
1.
Turn the ignition switch off and wait for 6 hours (8 or 10.5 hours).

Do not start the engine until checking Monitor Status. If the engine is started, the steps
described above must be repeated.
(c) Monitor Status
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Enter the following menus: Powertrain / Engine and ECT / Monitor / Evaporative System.
3.
Check the Monitor Status displayed on the Techstream.
HINT:
If Incomplete is displayed, the monitor is not complete. Make sure that the preconditions
have been met, and perform the Monitor Conditions again.
4.
2. PURGE FLOW MONITOR CONFIRMATION (P0441)
HINT:
Perform this monitor confirmation after the Key-Off Monitor Confirmation shows Complete.
(a) Preconditions
The monitor will not run unless:
The vehicle has been driven for 10 minutes or more (in a city area or on a freeway)
The ECT is between 4.4 and 35°C (40 and 95°F)
The IAT is between 4.4 and 35°C (40 and 95°F)
(b) Monitor Conditions
Release the pressure from the fuel tank by removing and reinstalling the fuel cap.
1.
Warm the engine up until the ECT reaches more than 75°C (167°F).
2.
Increase the engine speed to 3000 rpm once.
3.
Allow the engine to idle and turn A/C ON for 1 minute.
4.
(c) Monitor Status
Turn the ignition switch off (if ON or the engine is running).
1.
Connect the Techstream to the DLC3.
2.
Turn the ignition switch to ON and turn the Techstream on.
3.
Enter the following menus: Powertrain / Engine and ECT / Monitor.
4.
Check the Monitor Status displayed on the Techstream.
HINT:

INSPECTION PROCEDURE
NOTICE:
The Techstream is required to conduct the following diagnostic troubleshooting procedure.
HINT:
Using Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
Read freeze frame data using the Techstream. Freeze frame data records the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data
from the time the malfunction occurred.

CONFIRM DTC
(a) Turn the ignition switch off and wait for 10 seconds.
(b) Turn the ignition switch to ON.
(c) Turn the ignition switch off and wait for 10 seconds.
(d) Connect the Techstream to the DLC3.
(e) Turn the ignition switch to ON and turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(g) Confirm DTCs and freeze frame data.
If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.
NOTICE:
If the reference pressure difference between the first and second checks is greater than the specification, all
the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) are stored.
