Test Notes

Canada and some states or metropolitan areas in the United States require periodic Emission, or Inspection and Maintenance (I/M) Tests. All Ford products have been designed to pass these tests. If a Ford product fails an I/M Test, it is probable that 1) the engine or catalyst temperature was not warm and stabilized before the test, or 2) the vehicle had idled excessively before the test.

- If any emission components are replaced, perform the following before repeating the I/M Test procedure:
(1) Clear keep Alive Random Access Memory (RAM) (Powertrain Control Module Reset).
(2) To relearn some basic Adaptive Learning (trim) values, run engine at 2500 rpm for one minute and idle engine for two minutes.
