i have a 2000 and it's on the black plastic leading to the airfilter. you'll see a couple of wires going to it also. if you're replacing it clean it well with alcohol, take your battery cable off to reset your electrics and within a week it usually fixes the check engine light if that's your problem. It worked for me and saved me buying a 70.00 sensor. if questions e mail me at
