Can the EGR system be eliminated on my 1992 Ranger?
I have a 1992 Ford Ranger 2WD 2.3 4 cylinder 5 speed that is throwing codes for the EGR valve and the EGR valve sensor (it is the old style sensor, not the DPFE style). My question is this, can the EGR system be eliminated without the Check Engine light being on all the time and how much of an effect will it have on my gas mileage if any?
It can't be eliminated without the CEL light staying on. You will get worse MPG if it isn't working correctly, but not by much. Why don't you just replace the 2 sensors in question? I would first clean the EGR and throttle body of all the carbon, sometimes this prevents the EGR from working correctly.
