Where to get a ACT sensor?

[CTOESHO]

Well, according to my codes, my Air charge temperature sensor is out of wack. Where is the best place to get one of these? Autozone says they don't stock them, but I thought Scott said you could pick one up for $9.99. Anyone with ideas?

I may have, but I just checked AutoZone's site and found the following.

WELLS SU203, 3 MO Warranty, $11.99, AutoZone and AutoZone.com

It shows to be available at the stores and the web site.

Thanks Scott, I found it. I thought it was the Air Cleaner Temperature Sensor. Autozone sucks, it says $16.99 for me, just because I put in my zip code. You would think they would charge the same amount for an item no matter where you live. The same happened to me when I bought my rear calipers also.

What exactly is a air charge sensor, and whats it do?

 

[sdpatt]

The air charge temperature (ACT) sensor is a resistence temperature device that measures the temperature of the air. This sensor is located in the lower half of the air filter box to get an accurate measurement of the temperature of the air being drawn into the engine's inlet tract. The output from this sensor is used by the electronic engine control (EEC) computer, along with inputs from the barometric absolute pressure (BAP) sensor and the mass air flow (MAF) sensor, to determine the amount of oxygen drawn into each cylinder. It is this calculation that allows the EEC to inject the correct volume of fuel to obtain the desired 14:1 air-to-fuel ratio. The oxygen sensors in the exhaust system provide feedback to the EEC as to how close the calculation was and allows the EEC to adjust to achieve the best combustion for power and emissions. This is referred to as the "closed loop" mode of engine control operation.

You asked.

So the air charge sensor and the air cleaner temperature sensor is the same thing?

Yes.
