At begining I checked service Codes (engine service soon light )at Autozine, and I had codes P0401. P0133, P1131, WHEN i REPLACED oxygen sensor(closest to the engine) code P1131 went off,than I did clean up EGR valve and tube, after 30 miles checked again , it show P0401 and P1131 . How I can rid of these 2 codes.
Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

I have a 2000 Ford Taurus SE. I had a tune up and brakes done and smogged it and right after i got the transaxle light flashing and check engine , I took it to be checked and they gave me a transmission service and told me it would be like 1500 to replace all four sensors and I kinda balked! One week later out of the blue it begins leaking water from the under carriage somewhere. The diagnistic codes were like 7 of them and yet the car after service still won't go into passing or cruising gear and the rpms are very high just to go 40. Can anyone tell me what may have happened between tune up smog and taking a turn for the worse?
