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 °F (80 °C) and 212 °F (100 °C).
• MAP SENSOR less than 46.6 kPa (14 inHg, 350 mmHg).
• Vehicle speed 0 mph (0 km/h).
• IAT SENSOR between 32 °F (0 °C) and 212 °F (100 °C).

Procedure 

1. Connect the HDS to the DLC. Connect The HDS .

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.
