Codes
The ECM constantly monitors the engine by the use
of sensors on the engine. The ECM also uses
signals from the sensors to initiate sequential fuel
injection and make constant and instantaneous
changes to ignition timing, fuel delivery and throttle
position to maintain the engine's running condition
at its highest efficiency while at the same time
keeping exhaust emissions to a minimum. When a
sensor fails or returns signals that are outside of set
parameters, the ECM will store a fault code in
memory that relates to the appropriate sensor and
will turn on the Check Engine Light.
Refer to Fault Codes Section, How to Retrieve Ford
MSG-425 Engine Fault Codes for your specific
model of engine. Use the Fault Code Charts to aid
