System Operation
Exhaust Gas Recirculation (EGR) Systems
The EGR system controls the NOX
emissions. Small amounts of exhaust gases are recirculated back into
the combustion chamber to mix with the air to fuel charge. The
combustion chamber temperature is reduced, lowering NOX emissions

Inspection
NOTE:
Procedure 1 — Ambient Temperature below 21 °C (70 °F).
NOTE:
Proper A/C system diagnosis on a vehicle’s
compressor is dependent on correct refrigerant system charge and tested
in ambient temperatures above 21°C (70°F). Perform the following steps
to achieve normal operating pressures.
Drive the vehicle or run the engine until it reaches normal operati..
