Hyundai 28164-23700 Sensor Assembly-Air Flow

You can Select Your Vehicle to check if 28164-23700 fits your vehicle.

The checking procedure is applicable only to 2006 and earlier models, while 2007 through 2010 models require special equipment and procedures. The MAF sensor is situated in the intake duct between the air cleaner housing and the throttle body; to remove it, loosen the hose clamp screws. Without disconnecting the MAF sensor electrical connector, backprobe terminal 1 of the MAF sensor side of the connector with a suitable probe and connect a voltmeter. Check the output voltage at idle and then at 3,000 rpm, comparing your measurement with the specified voltage values. If the MAF sensor output voltage varies significantly from these values, it should be replaced. To replace the sensor, unplug the electrical connector by depressing the wire retainer and pulling it out, then loosen the hose clamps and remove the MAF from the intake duct. Installation follows the reverse order of removal.
