There was an extremely high failure rate for the DPFE sensor on various Ford products in 2001, 2002 model years. So common that I would suggest that you replace it with the revised part. Just make sure that the two rubber tubes that connect from the manifold to the sensor are not broken and are snug at both ends. Below is a technical service bulletin regarding the concern and repair: PENTICO/2010-06-05_021918

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I have a 2001 Lincoln Town Car with codes p1074 and p1074 and I was advised by a mechanic to replace the engine is that true?

Not sure on the code, it could be PO174. It may be an O2 sensor or problems with the intake and/or cyl heads.
I would make sure on the code and get a second opinion.

did you do the pin point testes? a fault code only tell s the sensor signal has a problem, that can be the actual sensor or the connector, or the wiring or the powertrain control module, with this sesor you can also hook the hoses up wrong and excessive exhaust back pressure can cause this as well.

My back passenger window will not go up in my 1999 Lincoln T. Car

Does the button on the passenger door work. They were prone to the drivers switches going bad. Usually the drivers window due to more use. They check engine light could be numerous things. Bad O2 sensor for example, Best to have it scanned. Could probably get the code at an AutoZone, Oriellys etc.
