Pinpoint Test EM: Emission Compliance: Introduction: Notes

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2013 Lincoln Navigator, 2013 Lincoln MKZ, 2013 Lincoln MKX, 2013 Lincoln MKT, and 2013 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.

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.
