Airtex 5S2046 EGR Pressure Feedback Sensor

The Airtex 5S2046 is an Exhaust Gas Recirculation (EGR) Pressure Feedback Sensor, also known as a DPFE (Differential Pressure Feedback Electronic) sensor. This critical emissions system component monitors and measures pressure within the EGR system to ensure proper exhaust gas recirculation back into the engine cylinders.

Key Features:

• Engineered and tested to meet or exceed OE specifications
• Direct replacement for OEM part numbers including DPFE15, F77Z9J460AB, VP8T, and others
• Features updated designs and technology for enhanced performance and longevity
• Provides instantaneous pressure data to the vehicle's onboard computer for optimal EGR valve operation
• Helps maintain proper emissions control, fuel economy, and engine performance

A failing DPFE sensor can trigger the Check Engine Light and cause various performance issues including rough idle, poor fuel economy, decreased power and acceleration, or stalling. This sensor is typically located near the EGR valve, behind the upper intake manifold, and features two vacuum hoses on the bottom with an electrical connector on the side. The EGR system plays a vital role in reducing hydrocarbon emissions and helping vehicles pass emissions inspections.
