Code p0102, on either the 3.4 or 3.8 (3800) v6 engine is a problem in the Mass Air Flow sensor (MAF). If any work has been done to it just prior to this code, then you need to make sure the air cleaner, duct work, breather tubes, etc. are properly connected and not loose. If that is OK, then may have a bad, or dirty sensor.

Had a po102 code on a 2002 3800 engine chevy check voltage at 12 volts.cleaned sensor. reset code now it says po102 pd with no engine,but engine stalls when driving


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

CODE PO102 after Mass Air Flow Sensor replaced


Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

Code po102 came up on my daughter's 2002 Buiick Le Sabre the engine is a 3800 v-8


You can remove the mass air flow sensor with some carb cleaner. You will see 2 wires inside of the sensor to clean. If it does not work you will most likely need a mass air flow sensor.
