Exhaust Gas Recirculation (EGR) Cooler Bypass Valve - Transit
The exhaust gas is directed through the EGR cooler by the EGR cooler bypass valve to remove heat before entering the intake manifold. The EGR cooler bypass valve is internal to the EGR cooler.
When the EGR cooler bypass valve solenoid is commanded off by the PCM, the EGR cooler bypass valve is closed. When the EGR cooler bypass valve is closed, the exhaust gas passes through the EGR cooler to the intake manifold.
When the EGR cooler bypass valve solenoid is commanded on by the PCM, the EGR cooler bypass valve is opened. When the EGR cooler bypass valve is open, the exhaust gas passes directly to the intake manifold without passing through the EGR cooler.
