EVAP Control System Monitor and Readiness Code

Evaporative Emissions (EVAP) Control System Monitor and Readiness code

NOTE:
- All readiness code are cleared when the battery is disconnected or when the ECM is cleared with the OBD II scan tool or Honda PGM Tester.
- The enable criteria must be repeated if the intake air temperature (IAT) drops lower then 36 °F (20 °C) from its value at engine start up.

Enable Criteria
- At engine start up, ECT and IAT are higher then 32 °F (O °C), but lower then 95 °F (35 °C).
- At engine start up, the ECT and IAT are within 12 °F (7 °C) of each other.

Procedure
1. Connect the scan tool to the vehicle's data link connector (DLC), and bring up the tool's generic OBD II mode.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about 2.5 miles (1.6 km), the readiness code should switch from incomplete to complete.
4. If the readiness code is still set to incomplete, check for a temporary DTC. If there is no DTC, one or more of the enable criteria were probably not met; repeat the procedure.
