On air box right befor maf sensor
what is your ?, a MAF is basicly a IAT The Mazda Protege and Protege 5 2.0L engine has an IAT Sensor located just past the factory air filter box. It is a two wire sensor that plugs into the intake tube via a rubber grommet. The three wire plug in the Mass Air Flow Sensor. DO NOT Unplug either of these sensors while the vehicle is running or key turned to accessory. Will cause a flag in the computer and turn on the Check Engine Light. Hope this helps.
The signal wire should be Tan. You should have a Yellow, Black, and Tan Wire. The Yellow being you MAF Sensor Signal. The Black being a Low reference voltage. Then your Tan your IAT sensor signal.

What if your maf sensor doesn't have a wire like this (frequency type)?* If your maf sensor doesn't have a wire with this varying voltage signal, then you have a frequency based sensor.* You will have probably two wires with a negative ground signal running through them. That's the wires to focus on. One of these ground wires will be the one to hook the enhancer up to.* We found the correct ground wire to enhance through trial and error. There were only two wires with a negative- signal to test.* When the enhancer was installed on the correct negative wire, the vehicle responded to the mpg max enhancer just like any voltage type map sensor would.* You should be able to make the engine shut off at will by adjusting unit to a full lean condition.
The intake air temp sensor is included in the MAF sensor.The power to the MAF is black with a blue line.The MAF ground is black with a green line.The MAF output voltage wire (used for nitrous or methanol injection) is yellow with a red line.
replace your MAF sensor.
The MAF sensor has a tiny platinum wire in it.
{| |- | MAF sensor - air flow sensor signal out of range. Possibly due to dirt build-up in the throttle bodies, or on the hot wire airflow sensors. |}
Trouble code P0101 means: MAF Sensor Signal Range/Performance
"Noisy" because the engine is vibrating more than normal? Low idle will cause the engine to shake. Low idle can be caused by - Dirty/clogged/sticking EGR valve - Vacuum leak or air intake leak - Dirty MAF sensor
