    I have a 06 tahoe LT that the check engine light is on. Originally the tighten fuel cap message came on and caused the light. I got the light reset and replaced the cap. The next day the light came back on and was the same code. do I need to replace the fuel pressure vapor sensor and if so how hard is it and where is it located.
    Thanks for the help,
