no I just need to have it turned off

all data says the light comes on at 60k then 82k then 120k at 60k &120k your suppose to rpl or clean egr valve and at 82k repl 02 sensor then connect a diag read out box to reset maint light. sounds like you need to see a mech with these capibilities. hope this helps

Thank you I do know that it comes on at certain millage and I think it is about replacing o2 senser I have one to replace it with I am just not sure how to turn off light once part is replaced or will it shut itself off after part is replaced??

it has to be turned off with a DIAG READ OUT BOX. call around and see who can reset it for you
