I was trying to install one of those "computer chips" that modified your ecu input, bla, bla, bla to get more power (yes, yes, i know, i know.... call bama chips, call bama chips... BUT I'M BROKE!!!!)... anyway... install went ok but after the 1rst couple of runs the "check engine light" came on... I followed the "what went wrong" rescue sequence and the light went away for a while but it came right back...


i emailed the guy who sold the item and he said the only thing that he could think off is that i installed the chip to the wrong sensor...

the chip is supposed to "bridge" the input/output between the AIT sensor and the ECU.... well I thought the AIT sensor was the one right next to air intake "sucking end" .... am i wrong?

does anyone know where the AIT sensor is located for a 2001 x sport???

thanks.

I am nor familiar with the term AIT. Do you mean the intake air temperature sensor?

Yeah, I imagine he's talking about the IAT (intake air temp) sensor

The sensor just after the air filter is both the MAF (mass airflow) sensor and the IAT in one.

That being the case, the IAT sensor on my '99 is built into the NAF, not sure about his.

Intake Air Temp Sensor... i guess i'm dislexic (or however you write it)

sorry about that...

Yes, it is the Intake Air Temp sensor... actually the manufacturer of the chip said that some cars have a "combo" sensor... I guess the IAT and MAF???

I called ford to ask this and they want to charge me some $$$ (ain't that something??? )

i checked carefully and the only sensor that i found was the one as described before... other than that, i think the nearest sensor in the intake line would be somewhere inside the engine where the intake pipe comes into??? i don't know

4 or 5 can't remember...
It should either be 4 or 6. If you have 6, then the IAT is in the MAF.

Maybe this will help you.

The check engine light might be from your fuel running too lean or you o2's acting up. Could you tell a difference in power?

sure did... if you were standing at a red light and tried to punch it hard, the torque/hp was none existing, it took for ever to get to 2500 rpm and/or 40 mph, but the after that, there was a little kick and rpm rev'd up quick... shifting was al a mess, too.

don't know since i'm not electronics expert, but i think i know what you are talking about... probable yes, since it was cheap (about $30.00)...

i saw what they had on ebay, and i thought i should have gone with one of those $5.99 ones... if results were going to be the same.
