PINPOINT TEST EM : EMISSION COMPLIANCE
NOTE:
Canada and some states or metropolitan areas in the
United States require periodic emission, or inspection/maintenance
tests. All Ford products are designed to pass these tests. If a Ford
product fails the test, the most likely causes are:
-
The engine or catalyst temperature are not warm and stabilized before the test.
-
Excessive idling by the vehicle before the test.
Normal Operation and Fault Conditions
If any new emission components are installed,
carry out the following steps before repeating the
inspection/maintenance test procedure:
-
Reset the KAM. Refer to Resetting The 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.
Verifying an excessive grams per mile (gpm) indication using a parts per million (ppm) reading.
For excessive vehicle gas readings, compare the
actual gpm reading to the gas cutpoint level needed to pass testing.
This gives an indication of how much the ppm reading has to be reduced
(if the actual reading is twice the cutpoint, the baseline reading has
to be cut in half or more).
Example:
-
The actual HC produced by a vehicle is 1.6 gpm. The cutpoint for HC in this example is 0.8 gpm. The actual reading is twice the cutpoint.
-
The HC
reading obtained for the same vehicle during the baseline drive averages
440 ppm. In order for this vehicle to pass the inspection/maintenance
test, the HC reading from the verification trip must be at least half of the baseline reading, or an average of 220 ppm or less.
-
This method only gives a general idea of how
much the ppm reading needs to be reduced in order for the vehicle to
pass an inspection/maintenance test that calculates gpm. This test is
not exact. Experience still has to be used to determine if the emission
readings are reduced enough for the vehicle to pass the
inspection/maintenance test.

Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.

DTC |
Description |
Fault Trigger Condition |
PCM P0420:00 |
Catalyst System Efficiency Below Threshold (Bank 1): No Sub Type Information |
Sets when PCM detects the bank 1 catalyst system efficiency is below the acceptable threshold.
Under normal
closed loop fuel conditions, high efficiency catalysts have oxygen
storage capability. As catalyst efficiency deteriorates, its ability to
store oxygen declines. Refer to the Catalyst Efficiency Monitor
description for additional information.
Diagnose any base engine concerns. Refer to the appropriate 303-00 section, Engine System.

storage capability. As catalyst efficiency deteriorates, its ability to
store oxygen declines. Refer to the Catalyst Efficiency Monitor
description for additional information.
