VALVE, Short Runner: Description: Description

The intake manifold features a dual shaft Short Runner Valve (SRV) system to maximize both low end torque and peak power. The SRV is bolted to the rear of the intake manifold and can be service separately from the manifold.

The SRV system operates under Wide Open Throttle conditions to maximize engine performance. When activated by the PCM, the SRV actuates a mechanical linkage to redirect the intake air flow to eight short runners. The PCM looks for a signal feedback when the actuator is activated. If the signal feedback is not present, the PCM sets the DTC.
