Question about 2000 Ford Expedition
If its a low flow code replace the DPFE sensor. If you do a resistance check of it it will prabably be out of specs. Also make sure the two hoses are hooked up and arnt cracked. Also blow thru each one to make sure the tubes going into the exhaust arnt clogged. Also make sure the grn hose going to the egr valve is plugged in. Also apply vacuum to the egr valve to make sure it holds vacuum. If it doesnt then the vlave is bad.
