Evaporative Emission (EVAP) Control System Monitor and Readiness Code

NOTE:  All readiness codes are cleared when the 12 volt battery is disconnected, if DTCs have been cleared, or if the PCM is reset with the HDS.

Enable Criteria 

• 12 volt battery voltage is more than 10.5 V.
• Engine at idle.
• ECT SENSOR 1 and 2 between 176 deg. F (80 deg. C) and 212 deg. F (100 deg. C).
• MAP SENSOR less than 46.6 kPa (14 inHg, 350 mmHg).
• Vehicle speed 0 mph (0 km/h).
• IAT SENSOR between 32 deg. F (0 deg. C) and 212 deg. F (100 deg. C).

Procedure 

1. Connect the HDS to the DLC.

2. Start the engine.

3. Select the 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 Pending DTC. If there is no DTC, one or more of the enable criteria were probably not met; repeat the procedure.
