Evaporative Emission (EVAP) Control
System Monitor and Readiness Code
NOTE: All readiness codes are cleared when the battery
is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
Enable Criteria
• Battery voltage is more than 10.5 V.
• Engine at idle.
• ECT SENSOR 1 and SENSOR 2 between 176 °F (80 °C)
and 212 °F (100 °C).
• MAP sensor less than 46.6 kPa (14 in.Hg, 350 mmHg).
• Vehicle speed (VSS) 0 mph (0 km/h).
• IAT SENSOR 1 between 32 °F (0 °C) and 212 °F
(100 °C).
Procedure
1. Connect the HDS to the DLC.
2. Start the engine.
3. Select EVAP TEST in the INSPECTION MENU with
the HDS, then select the FUNCTION TEST in the
EVAP TEST MENU.
• If the result is normal, readiness is complete.
• If the result is not normal, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, one
or more of the enable criteria were 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 when the battery is
disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
Enable Criteria
ECT SENSOR 1 at 140 °F (60 °C) or more.
Procedure
1. Start the engine.
2. Test-drive the vehicle under stop-and-go conditions
with short periods of steady cruise. During the
drive, decelerate (with the throttle fully closed) for
5 seconds. After about 3.5 miles (5.6 km), the
readiness code should switch from incomplete to
complete.
3. Check the readiness codes screen for the AIR FUEL
RATIO (A/F) SENSOR in the DTCs MENU with the
HDS.
• If the screen shows complete, readiness is
complete.
• If the screen shows not complete, go to the next
step.
4. Check for a Temporary DTC. If there is no DTC, the
enable criteria was probably not met. Select the
DATA LIST MENU. Check the ECT SENSOR 1 in the
ALL DATA LIST with the HDS. If the ECT SENSOR 1
is less than 140 °F (60 °C), run the engine until it is
more than 140 °F (60 °C), then repeat the procedure.
