high idle! ECU reads code 12 (MAF)

[bonestock240sx]

so i sprayed intake cleaner and messed up the MAF but i've tried 3 different MAF sensors and it doesn't change the idle and the ECU reads a code 12 which is maf sensor circut. what else could cause that ? the idle is like 2 grand even up to 2500 so idk. help me out thanks. and yes i've already looked and searched all over

try to erase the code by switching modes to 2 & back to 1 first & recheck again. If it's still there, next step is to check the wiring & connectors between maf & ecu. Check the maf connector for any damage or corrosion, if ok, check black/white wire if u have 12 volts at maf w/ ignition on. If ok, check voltage on input signal wire at maf w/c is the white wire, at idle voltage should be bet. 0.8-1.2 volts, the 3rd black wire is the ground wire.Make sure u have wiring continuity between maf & ecu. If all checks ok, last resort is u could have a bad ecu, maf driver (transistor) at ecu probably failed., try to swap a known good ecu.
