1- the abs controll unit
2- MAF

i had my abs unit repaired for this by po before i bought the car. im not sure if its a diy or even if there is a way to check. i would remove it and send it out to be tested.

It's pretty clear from those codes that the MAF is the issue.
ABS control unit is still communicating and the only fault is that it is getting bad info from the ECU. TCU is complaining about the same thing. ECU says, the problem is bad info from the MAF.
