• The intake manifold is now equipped with an EGR throttle plate.
• The purpose of this plate is to lower the manifold pressure which will allow exhaust gases from EGR to flow freely into the intake manifold.
• NOTE: The PCM will activate the EGRTP actuator and perform a full sweep of the throttle plate for each key cycle with the IAT temperature greater than 0 degrees Celsius (32 deg. F.)
