Does a 2003 Mazda Protege LX have an IAT 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.
