I noticed when I was installing my new headlight bulbs today that there's a little box near the front of the engine compartment that says "Boost Sensor". Does anybody else have this on their car? Does it really serve a purpose? I saw "Boost" and I got excited even though I know I don't have a turbo or anything. So I was just curious as to what that was for. Thanks for your help!

 

I have it.. not sure what it does. but i do "think" i know that the stealership replaced them under recall when i had my evap system fixed

 

Yes all the maxs have them.Not sure what it does.

 

It senses boost

 

So far what I have gathered is that the boost sensor on our maximas is because of are semi ram air intakes. As the pressure in the intake system and the intake plentium rises it automatically adjusts the fuel and the timing like a boost sensor on any turbo or SC car.

 

Thats also known as the MAP sensor...

 

I believ it measures altitude.

 

MAF*

MAP is different
