Pinpoint Test EM: Emission Compliance: Introduction: Notes
NOTE:
Canada and some states or metropolitan areas in the United States require periodic emission, or inspection/maintenance (I/M) tests. All Ford products are designed to pass these tests. If a Ford product fails an I/M test the most likely causes are:
- the engine or catalyst temperature was not warm and stabilized before the test.
- the vehicle idled excessively before the test.
If any new emission components are installed, carry out the following steps before repeating the I/M test procedure:
- Reset the keep alive memory (KAM). Refer to RESETTING THE KEEP ALIVE MEMORY (KAM) .
- To relearn some basic adaptive learning (trim) values, run the engine at 2, 500 RPM for 1 minute and idle the engine for 2 minutes.
