The DPFE (Delta Pressure Feedback EGR) sensor on a 1994 Mercury Grand Marquis is typically located near the EGR valve, which is on the engine's intake manifold. It is mounted on or near the firewall, often near the driver's side of the engine compartment. The sensor has two rubber hoses connected to it, which measure the pressure differential in the EGR system. To access it, you may need to remove some engine covers or components for better visibility.
