The Premium CarQuest Vehicle Solutions line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Switch monitors system pressures, aiding in proper and efficient control of the compressor, fans and system levels. An improperly functioning A/C Pressure Switch will provide erratic or inaccurate actuation and operation, severely affecting system performance and function. Without reliable and accurate actuation from a properly functioning A/C Pressure Switch, critical components and the system as a whole are left unregulated and unprotected which can lead to excessive wear and tear on critical components and costly system damage.

Product Features:

Made to OE spec to ensure a proper fit, form and function.
Sensors are engineered for precision performance, durability and a long service life.
All units are tested using advanced end-of-line equipment that pressurize the A/C Pressure Switch, confirm proper calibration and functionality, and check for leaks to ensure each A/C Pressure Switch meets manufacturing specifications before packaging.

The EGR system is an emission control device designed to recirculate exhaust gas into the engines air intake system and back to the combustion chamber to control nitrogen oxides or NOx. The chemical NOx is created when oxygen and nitrogen are heated above 2,800-degree F. Exhaust gas, or gas that is displaced from the combustion chamber, contains little to no oxygen molecules. By recirculating this gas back into the combustion chamber fewer oxygen molecules are available for the combustion event which will therefore create a cooler combustion event. The EGR valve can be actuated by engine vacuum or electronically by the engine control module. The EGR Valve Position Sensor allows the engine control module to monitor the location and operation of the EGR valve.

Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
