CODE PO102 CAR STALLED AND THEN ON RESTART ENGINE LIGHT WAS ON AND THERE IS CODE PO102 MAF-VAT LOW INPUT. CAR HAS A 3.8 NO SUPERCHARGER AND NO MAF WHAT IS VAT ANY HELP WOULD BE GREAT

MAF sensor trouble code P0102 caused by bad ground GM 3100
Repair Buick LeSabre P0102 MAF Trouble Test it if you have the tools an you know how .

code po102 refers to mass air flow(MAF) sensor/volume air flow (VAF) sensor---low input======causes --wiring short to ground---MAF/VAF sensor ---ECM

code p0102 refers to mass air flow(MAF) sensor/ volume air flow(VAF) sensor --low input===causes--wiring short to ground--MAF/VAF sensor/s--ECM

clean or replace the MAF/VAF senspr

code p0102 refers to MAF/VAF sensor ---low input ===causes --wiring short to ground. MAF/VAF sensor
code po172 refers to system too rich --bank 1=== causes ---intake blocked --EVAP canister purge valve---fuel pressure ---HO2S sensor
code po random misfires ---plugs --wiring ---injectors--low compression
code po305 refers to cylinder 5 misfire detected ===causes --engine mechanical fault--ignition/ fuel system ---injector ---ECT/MAF

I would check that the air filter is not blocked first as it affects the MAF/VAF sensors . Have a fuel pressure system pressure test done

code p0102 refers to mass air flow(MAF) sensor /volume air flow (VAF) sensor -low input. Causes ---wiring short to ground --MAF/VAF sensor ---ECM.

po135 is o2 sencer on drivers side. will be the first one. po300 is random/multiple misfire.po404 is a egr code. po102 mass air flow circuit low input. po440 evap emission control system malfunction

P0102 is the generic DTC (Data Trouble Code) for (Mass or Volume Air Flow Circuit Low Input), and it would most likely be a fault with the MAF (Mass Air Flow) sensor.

The MAF sensor could be dirty or faulty, and there might even be restricted air flow to the MAF sensor (like a plugged up air filter). Also be sure that there are no air or vacuum leaks in the air induction system especially between the MAF sensor and the throttle body and that the hose clamps on the air induction system are all tight.

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 ...

Trouble Code: P0102


MAF Sensor Circuit Low Input
Possible Causes:



Check for leaks between MAF sensor and throttle valve control module Voltage supply faulty. Sensor power circuit open from fuel pump relay to MAF sensor Sensor signal circuit open (may be disconnected) from ECM and MAF Faulty ground cable resistance between connector terminal 1 and Ground MAF Sensor malfunction Sure hope this helped you and good luck.

code PO102 is mass air flow sensor circuit low frequency condition.what it is saying.MAF sensor element hot wire contaminated or sensor failed.MAF sensor signal shorted to ground or grounded circuit problem.MAF sensor wiring routed close to ignition wires generator solenoids or electric motors.PCM has failed.
