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 "Vehicles it fits" section for the full application and engine list.
- Emission-focused quality control: built by a global manufacturer of emission components, with quality control maintained through the manufacturing process from componentry to finished product.
- Brass and high-temperature plastic housing: constructed to OEM specification for precision fit and performance.
- Feature-rich EGR design: designed and built with componentry aimed at market-leadership performance.
- Special thermal elements: specially designed for improved performance.
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.

Frequently Asked Questions
What does a ported vacuum switch do?
It senses engine coolant temperature and opens or closes vacuum passages, routing ported vacuum to emission-control devices such as the EGR valve and distributor advance at the intended operating conditions.
Will the PVS113 fit my vehicle?
It's a direct-fit replacement for many 1977-1988 Chrysler, Dodge and Plymouth models. Check the "Vehicles it fits" section to confirm your exact year, make and model before ordering.
What is the switch made of?
It's carefully constructed with a brass and high-temperature plastic housing built to OEM specification for precision fit and performance.
What are signs this switch may need replacing?
Vacuum being routed at the wrong temperature or emission-system faults can point to a failed switch. Diagnose the cause first, since these symptoms can have other sources.
What numbers does this part interchange with?
It cross-references 2-1191, 21191, EC971, 4006587, 4049208 and 12352215.
