MAF on a 3.4?

[A fireman]

I was looking over my engine compartment as i swapped out my air box for a K&N cone filter when i saw a plug sitting unused, it located on the drivers side just behind the air box. If I'm right its for a MAF sensor. first dose a 3.4 need a MAF and if no will it benefit or even work with my PCM?

Re: MAF on a 3.4?

i think it may be your IAT(intake air temp) and your car will never work without a MAF

Re: MAF on a 3.4?

you don't have an MAF, none of the 3.4's do. The PCM reads off the TPS and o2's to guess on incoming air.

i would need to see a pic of the sensor, but it could be your ABS, IAT, or some other random sensor.

do you have a manual or automatic?

Wow... :spank: They use a MAP sensor on 3.4.

Do all your headlights work? Do you have foglights? That looks alot like a light plug.

Re: MAF on a 3.4?

yes all my lights work no i don't have fogs ( not from the factory) it is located exactly where the MAF sensor should be on a V8 for 1994 and is identical to the one pictured in my haynes manual.

Re: MAF on a 3.4?

I will look at my 1993 Firebird later, but I believe I have the same plug in the same spot. I am pretty sure it is for the air pump, if so equipped. Only manual transmission cars came with an air pump, but all of the cars have the wiring harness.

The PCM does use the TPS to fine tune curves, but it uses the MAP a bit more.

Correct. This is for the AIR Pump.

Thank you.
