Po102 code

Asked by Mar 06, 2017 at 05:09 PM about the 2000 Buick Park Avenue Ultra FWD

Question type: Maintenance & Repair

Buick Park Ave Ultra 2000. Car will drive fine for
about 25 highway miles, then, when coming to a
stop, the RPM will stick high, while still in drive
(about 1,500). Then when I put it in park the RPM
go up to about 3,000 and stay there. It throws the
MAF sensor code, so I cleaned it. Works for a
couple months then does same thing, AND the
battery won't hold a charge.

Your battery could be old or shorted out. The battery should be tested along with the charging system, (alternator). Inspect the battery cables to insure there in good shape, clean and tight....P0102 BUICK - Mass or Volume Air Flow Circuit Low Input...Possible causes; Faulty mass air flow sensor, Intake air leaks, Dirty mass air flow sensor, Dirty mass air filter, Mass air flow sensor harness is open or shorted, Mass air flow sensor circuit poor electrical connection...Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.


also ensure that the air filter is clean- if the filter is clogged you can have the p0102 error code. good luck

Thanks guys. Any guess on why the RPM would behave so erratically?

Also when I bought the car it had a sh*tty Walmart battery in it that was still under warranty, so when they go bad I just keep bringing them back to get a new one for free. It always runs fine on a fresh battery.


Make sure the charging system is working. Just stop at an auto parts store and have it checked.


Well, once the system thinks that the MAF is voltage is low, the ECU dumps fuel and adjusts the TB flap- that explains the high idle.
