Evaporative Emissions (EVAP) Control
System Monitor and Readiness Code
NOTE: All readiness codes are cleared w h e n the battery
is disconnected, DTCs are cleared, or w h e n the PCM is
reset w i t h the HDS.
Enable Criteria
• Battery voltage is higher than 10.5 V.
• Engine at idle.
• ECT sensor between 176 °F (80 °C) and 212 °F (100 °C).
• MAP sensor less than 46.6 kPa (14 in.Hg, 350 m m H g ) .
• Vehicle speed 0 m p h (0 km/h).
• IAT sensor between 32 °F (0 °C) and 212 °F (100 °C).
Procedure
1. Connect the HDS to the vehicle's data link
connector (DLC).
2. Start the engine.
3. Select EVAP TEST in the INSPECTION MENU w i t h
the HDS, then select the FUNCTION TEST in the
EVAP TEST M E N U .
• If the functions are n o r m a l , readiness is complete.
• If the functions are not n o r m a l , go to the next
step.
4. If the readiness code is still not set to complete,
check for a T e m p o r a r y DTC. If there is no DTC, one
or more of the enable criteria w e r e probably not
met; repeat the procedure.
Air Fuel Ratio (A/F) Sensor Monitor and
Readiness Code
NOTE:
• Do not turn the ignition switch off during the
procedure.
• All readiness codes are cleared w h e n the battery is
disconnected, DTCs are cleared, or w h e n the PCM is
reset w i t h the HDS.
Enable Criteria
ECT at 158 °F (70 °C) or higher.
Procedure
1. Start the engine.
2. Test-drive the vehicle under stop-and-go conditions
w i t h short periods of steady cruise. During the
drive, decelerate (with the throttle fully closed) for
9 seconds. After about 3.5 miles (5.6 km), the
readiness code should switch f r o m incomplete to
complete.
3. Check the readiness codes screen for the air fuel
ratio (A/F) sensor in the DTCs M E N U w i t h the HDS.
• If the screen shows complete, readiness is
complete.
• If the screen shows not c o m p l e t e , go to the next
step.
4. Check for a T e m p o r a r y DTC. If there is no DTC, the
enable criteria was probably not met. Select the
DATA LIST M e n u . Check the ECT in the ALL DATA
LIST w i t h the HDS, If the ECT is lower than 158 °F
(70 °C), run the engine until it is higher than 158 °F
(70 °C), then repeat the procedure.
