Hello all!
The check engine light came on at 54,000 miles on my 1998 Contour LX (V6 2.5L engine). I took it to AutoZone and they gave me the following "dealer specific" code: P1131. When I called the dealership, they said they would only tell me what it meant after I brought it in and let them diagnose it -- for $74! I did not say "No" but rather "Hell No!"
Using the wonderful resources on this website, I've found out that this code is: "Lack of upstream heated oxygen sensor switch -- Sensor indicates lean."
Can anyone please provide information as to what kind of work is required to resolve this? Any and all assistance would be greatly appreciated.
