Carquest Premium – Exhaust Gas Recirculation (EGR) Valve Position Sensor (Part No.EGC1043)

Exhaust Gas Recirculation (EGR) Valve Position Sensor

from

$41.99
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 Features:
  • Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
  • 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
  • 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
  • Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
  • Lead frame terminal size and location determined using image dimension measuring system or 3D laser scanner.
  • Application matched components ensures system operation in like new condition.
