Refer to Checking Monitor Status (See page ES-21).

The test value and test limit information are described as shown in the following table. This information is included under MONITOR RESULT in the emissions-related DTC sections:

• MID (Monitor Identification Data) is assigned to each emissions-related component.

• TID (Test Identification Data) is assigned to each test value.

• Scaling is used to calculate the test value indicated on generic OBD II scan tools. Thermostat

If pressure change in sequence 1 is greater than criterion 7, purge flow monitor is completed (functioning normally).

If pressure change in sequence 1 is smaller than criterion 7 and pressure change in sequence 2 is smaller than criterion 8, purge flow is insufficient.
