Anyone know what sensor this is? i was just recently lookin at my engine for an attack plan on changing my knock sensor and noticed this has nothing plugged into it and seems as if there is a vacumm line disconnected nearby also...any ideas?

 

look for a loose hose and plug and plug it up!! you'll find out when the extra powa kicks in or a cell kicks on...

 

Thats the problem bro, i cant see any "extra" plug anywhere near it, i have an emply plug next to my drivers headlight but its only 3 inches long something else i just found also....and the vac hose....no hose anywhere else....

 

looks like its got a part number on it. but i can't read it. try to get a better shot of the numbers.

 

i blew it up and the numbers are from the top--- k5146583 next row--- 7z09. dont know what the thing is next to the 7 in bottom row.

 

i did blow it up, i ran the numbers that i seen on it, searching came back with NOTHING

 

its obviously an option that your max did'nt have or need. i would'nt worry about it. i know its eggin you tho....

 

It looks like MAP sensor solenoid switch.

 

It looks like the auxiliary power unit for the rear ejection seat.

 

as map sensor switch?? when i bought the car the girl gave me a print out from autozone...said either map sensor or maf sensor.....hmmm

 

Or it might be this valve solenoid.

And she is right because, the MAP sensor is located right on your factory air intake snorkel and the MAF sensor is located near the left fender which is 4 times the size of what you've posted.

 

it could be, id have to look at it again to verify the tubing on it, if that is the case WTF is it for??

 

MAP = Manifold Absolute Pressure sensor
Tells the ecu how much air pressure is in the intake manifold to determine how much load the engine is under(helps ecu determine A/F ratio combined with readings from other sensors, MAF, TPS, etc...).

 

That would be the MAP/BARO switch solenoid valve.

 

I see... well i guess its time to search for a vacumm diagram from it to where it belonds and also where would the connector be.....

 

Just get any sort of vacuum line and tap it into any vacuum source. Doesnt matter where, just needs vacuum. The plug should be somewhere; if i remember, the pcm only uses the MAP as a reference/backup.

 

i dont see any connector....matter of fact i dont even see a map sensor on my car..... i know what the maf is i see that the intake snorkel was somewhat disconnected underneath...reconnected that, but i dont see no map sensor, and when i run a search for a 95 map sensor it comes back as 96-99....did they not use them in a 95?? or is google search just retarded? the only plugs i see is one directly on the side of the battery try, a 2 pin plug and then theres one near my front drivers corner assembly which has 3 pin connections...wtf are those lol...seems as if someone did something to this car they shouldnt have...

 

What year is your car?
