6.7L Power Stroke – EGR Cooler Bypass Solenoid


A duty cycle is applied to the solenoid from the PCM to turn vacuum to the actuator on or off. This change causes
the EGR cooler bypass door to move.
The EGR cooler bypass solenoid changes the state of the EGR cooler bypass door to either allow exhaust gases to bypass the EGR cooler or direct the gases through the cooler.
