Route ported vacuum to your emission controls on temperature cue with the Standard Ignition Ported Vacuum Switch (PVS113). A ported vacuum switch senses engine coolant temperature and opens or closes vacuum passages so devices like the EGR valve and distributor advance receive vacuum at the intended operating conditions. It's a direct-fit replacement for a wide range of 1977-1988 Chrysler, Dodge and Plymouth applications, including the Chrysler Cordoba, LeBaron, New Yorker and Town & Country; Dodge Aries, Aspen, Caravan, Charger, Daytona, Diplomat, Omni and Dakota; and Plymouth Caravelle, Horizon, Reliant, Turismo, Voyager and Volare. See the Buyer's Guide tab for the full application and engine list.
If a failed ported vacuum switch is the cause of your emission-system or vacuum-routing trouble, this replaces it. Diagnose the cause before replacing.
