I have looked (or, at least CALL myself looking), checked the manual and I still am not sure where it is. I KNOW the general area and I feel duffus, that I haven't located it. So, if someone could tell me where that sucker is, I sure would appreciate it. My truck won't start (again) and I am getting an "11" code, so I was going to swap out the sensor, especially since I already have one. Thank you.
