where is my egr valve regulator sensor located
I have a 1994 4.6 cougar and im pulling up an error code p0171 and im hoping its my egr valve regulator sensor (DPFE) and not the needing to replace the egr valve because ive heard its a pita. the only thing I see that would be close is a sensor close to the vacuum can by the front passenger bumper with two hoses going to it and a plug but it doesn't look like the one im seeing online. Im seeing that its on the firewall and its silver but I don't see it. Does anyone have any suggestions?
