I had my "servive engine soon" light come on. I took it to a mechanic to diagnose and he said the fuel tank pressure sensor was bad. They did a complete diagnostic, not with just a hand held scanner. They recommended that I replace the whole fuel pump because it has a bad check valve. I just had it replaced about 4 years ago. The fuel pump is working fine and all I want is the SES light to go off. I plan on doing this project myself so what I want to know is should I replace a 4 year old pump or will just replacing the pressure sensor make the light go out? Thank you

What does the fp have to do with the cel/sensor? If you feel while you are in there it should be done, different story.

is the sensor bad?
You also have vent lines that can get clogged or pinched. If you need to drop the tank to do this then I would think about doing the pump as well. Or you could leave the light on. Doing the pump is a lot of work and money just to clear a code,
