P1004 Chrysler Description
The Short Runner Valve (SRV) system is used to improve engine performance. The SRV system allows the intake charge air to bypass the long intake manifold runners between the intake manifold plenum and the intake manifold interface to the cylinder heads by providing a shorter runner directly between the plenum and the cylinder head interface The SRV position is controlled by a pneumatic/spring actuator and electronic solenoid valve. The Powertrain Control Module (PCM) compares the circuit feedback to calibrated closed range when the circuit is deenergized or to a calibrated open range when the circuit is energized.
