Essential Fuel and Emissions Systems for 2003 Mitsubishi Eclipses
Carquest Premium – Carquest Manifold Absolute Pressure Sensor, ECA2175 (Part No.ECA2175)
from
$122.99
Pressure sensors are used within several operating systems on the vehicle. Subjects in this category measure the pressure of both liquid and air to include air in a positive pressure and negative pressure range. Pressure sensors report out as the result of an electrical device called a strain gauge which produces an analog or digital signal output dependent on the needs of the circuit. Pressures may be very low such as barometric pressure, or extremely high such as in a high-pressure fuel injection system.

Carquest Premium – Carquest Exhaust Gas Recirculation (EGR) Valve Gasket, EVA1005 (Part No.EVA1005)
from
$4.99
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.
