Hi, just required you to know I he added your site to my Google bookmarks due to your layout. But seriously, I believe your internet site has 1 in the freshest theme I??ve came across. It extremely helps make reading your blog significantly easier…

The IAT sensor on the 1993 Ford Ranger 2.3L is not part from the MAF sensor. It has two wires, GRAY and GRAY/RED, where the GRAY one is the one to be modified, as the other wire is the sensor signal return wire. It is inserted in one side of the air filter housing. Its resistance chart is listed below, along with the resistor values that are the most easily found that can be used, as they are readily available.

50F (10C) – 58.7K (You may use – 56K GREEN-BLUE-ORANGE-GOLD)
68F (20C) – 37.3K (You may use – 39K ORANGE-WHITE-ORANGE-GOLD)
86F (30c) – 24.3K (You may use – 22K RED-RED-ORANGE-GOLD)
104F (40C) – 16.2K (You may use – 15K BROWN-GREEN-ORANGE-GOLD)
122F (50C) – 10.9K (You may use – 10K BROWN-BLACK-ORANGE-GOLD)
140F (60C) – 7.6K (You may use – 8.2K GRAY-RED-RED-GOLD)
158F (70C) – 5.4K (You may use – 5.6K GREEN-BLUE-RED-GOLD)
176F (80C) – 3.8K (You may use – 3.9K ORANGE-WHITE-RED-GOLD)
194F (90C) – 2.8K (You may use – 2.2K RED-RED-RED-GOLD)
212F (100C) – 2.0K (You may use – 1.8K BROWN-GRAY-RED-GOLD)
230F (110C) – 1.6K (You may use – 1.5K BROWN-GREEN-RED-GOLD)
248F (120C) – 1.2K (You may use – 1.0K BROWN-BLACK-RED-GOLD)

@John

In the 2009 Silverado 1500 (5.3L), we have the information that it should be a 5 wires MAF, with the IAT integrated on it, using 2 of those 5 wires, which are wire “D” (TANGERINE/BLACK) and wire “E” (TANGERINE).

The configuration is as follows:

A- YELLOW
B- PINK
C- BLACK/WHITE
D- TANGERINE/BLACK (IAT Signal)
E- TANGERINE (IAT Ground)

So you can wire the resistor in series with wire “D” (TANGERINE/BLACK) for increasing resistance value, which is equivalent to lower temperatures.

About the K&N filter, regardless of the brand, any high flow filter that is still capable of efficiently filtering incoming air is always recommended. Since all modern automotive equipment is geared with smart computers and sensors, the extra air flow will enable the computer to inject more fuel, producing more power. Fuel will have a more complete burning, being ecological too. It even does its part on economy, as a vehicle that feels powerful enough, won’t be pushed too hard as we do when a car feels lazy. More of a psychological thing than physical, but it does work to lower consumption.

Thanks John

I can at least provide the configuration on it.

The MAF has 6 wires and one of them (#6 – GRAY) is directly wired to the IAT sensor. The configuration is as follows:

1- GRAY/RED (Signal Return)
2- RED (Switched 12V)
3- BLACK (Ground)
4- TANGERINE/LT BLUE (MAF Signal 1)
5- LT BLUE/RED (MAF Signal 2)
6- GRAY (IAT)

The drawing below shows the above configuration.

I hope this helps.

Cheers,

Richard

Your MAF sensor, as far as the information I could get, has 7 wires, where wire #5 and #6 are connected to the IAT. It is as follows:

1. GREEN/YELLOW
2. GREEN/WHITE
3. WHITE/GREEN
4. RED
5. BROWN ——— (Sensor Return)
6. RED/BLUE —— (IAT)
7. GREEN/BLUE

Cheers.

The report of your results will be more than welcome here whenever you do the experiment, specially with and without the turbo fan. I have heard that it is more of an air restriction than a boost, but can not tell yet, as I have not experimented with it.

“I am looking for 2009 honda accord V6 IAT sensor wiring diagram. The module is in with the MAF.(5 wires) Which 2 colored wires are for the IAT? Thanks
John”

On your car, which I guess it is 2.7L, as in the 3.0L the IAT sensor is a separated part, the MAF has 5 wires and the IAT is independently connected to wires #1 (GREEN/YELLOW) and #2 (RED/YELLOW).

The configuration should be as follows:

1- GREEN/YELLOW (IAT 1)
2- RED/YELLOW (IAT 2)
3- RED/GREEN
4- BLACK/RED
5- BLACK/YELLOW

The same advice as to the other reader, if any of the colors is different in your car, it might be an indication that the configuration is different.

Best regards,

Richard

“I want to try the IAT mod on my 2008 Hyundai Tiburon GS 2.0L It got IAT/MAF sensor can you help identify which 2 wires (color/stripes) for IAT? thanks”

As our database, it has 5 wires and the IAT is wired at wire #5 (YELLOW/BLACK). The configuration is as follows:

1- WHITE/BLACK
2- ORANGE
3- GREEN/WHITE
4- BLACK
5- YELLOW/BLACK (IAT)

Please remember, if any, even only one wire, is not the color as described here, it means that the configuration might not be the same.

Best regards,

Richard

Unfortunately, yes, it is a simple resistor. Instead of investing on that scam, you can try it by yourself with the information posted here.

I wouldn’t buy anything from that site, as most things are not real performance products and I say “most”, because I saw a few of them, not all, but immediately realized that it is not worth it.

Anyway, the last record of that website domain is on “DomainsByProxy”, which seems to be selling the domain, so I guess that they are out of business anyway. Please don’t throw away your money with that.

Best regards,

Richard

wow. Im glad I cam across your website. I was about to purchase some ‘tuning’ stuff from the net. Do you think the gadget here is the same thing as a resistor? cos its supposed to be connected to the IAT.

Also can you comment if any of the stuff here might work? cos i really wana get something to improve my car’s performance.
