Hey guys, where would be the best {cheaptest} place to buy a vane air temp. sensor for my MAF?? Is it very difficult to fit my Autothority MAF with one of these??

The easiest thing to do is look on Ebay for a cheap , used VAF.
Then swipe the temp sensor from it.
Drill a hole in your MAF pipe and mount the temp sensor in a bed of
epoxy.
Then wire it in.

Tiz what I did for my Huntley MAF. Some say you'll get double temp compensation but I found it far easier to tune (and hold a tune) with the sensor wired in rather than leaving it up to the ARC-2 only.

It does make a big difference.
90 degrees or 20 deg... I start fine, idle fine and runs great.

Do I have to run the wires to my VAT all the way from the DME, or are there wires under the hood that I can splice them into??

hally

wires into the existing AFM harness
1 - Temp Sensor
2 - VAF Output
3 - 5V Reference
4 - Ground
you u are replicating the temp sensor integrated into the stock device.

Is the green wire to the temp sensor??

awilson40

yes,

Replacement part for the air intake thermister (NTC1) is NTC-202 from Jameco. Cost is $0.59 each.

Hello, I finally got ahold of an air intake temp sensor and there are 2 wires coming out of it. Are one of these wires the ground or do they both need wired to the green wire on the harness??

hally

one to the green wire (1), the other to the signal ground wire (4)

where and how much?

Doyle623

I actually took it out of a Hyundai airbox, but I figure it will work just fine once I fit it into my MAF j-pipe.....I'm sure you could find a cheap one on ebay

Bri Bro

How do you know Hyundai uses a 2K Thermistor? I guess the 59 cent cost of a new one is too much.

Doyle623

Maybe I should just go with the thermistor...beab951, so I drill a small hole, use epoxy to hold it into place, then wire one part to the green wire and one to the other to the signal ground wire?? Or am I on the wrong track now?
