U may hav to clearit by disconnect batt afew min. Also u cud hav more issues that dont show on acode reader. They r just approximate. U really need a factory scanner to display adata stream that pinpoints problm. Private shops hav them. Adealers tool only goes back bout fiveyrs
-Air flow sensor might be too dirty or bad connection. Try clean it then erase the code to see it will come back on about 20-40 mile. If not come back at all then the problem is solved.
-If it come back about 20-40 mile then possibly the sensor need to be replaces well.
This is the Mass Air Flow Sensor. It's a screen-like device located on the air intake line to the throttle body. It measures the flow rate and density of air entering the engine. The code can mean a few possible things:
Try replacing the air filter first. Remember that engine codes must be reset or they will remain in the computer even after repairs. If that doesn't work you can remove the MAF and clean it with a MAF Sensor approved spray cleaner. If you use the wrong cleaner you will destroy the MAF. If cleaning the MAF don't work, then replacement is indicated.
The generic code is for the mass air flow sensor. But I don't show this code on a GM product. You may need a shop manual or research it online for details.
HI, The DTC set PO102 is for your MAF (mass air flow) sensor. this sensors measures the air moving past it my heating a fine wire much like one inside a light bulb. Even cleaning these will not get the contaminates off. That little wire gets very hot and if dirt gets on it it will bake to it then this throws off its readings for your computer. If you checked and you have your 5 volt reference for this sensor the only other thing is to replace it. You can get re-manufactured one now at any major parts store. Good luck
po102 is a maf sensor.it is located after or on air box inlet tube, that were air goes into engine,this sensor measures the air ,tell computer how to mix gas, hope this helps goodluck.
P0102 Mass or Volume Air Flow Circuit Low Input. The actual Mass air Flow sensor is damaged. replace this sensor asap. it is located on the top of the throttle body.
