For the ABS error coming is U2100 / U0140/U0100
Customer: replied 2 months ago.
Now fault P0172 and P0175 is gone but P0101appear
Expert:  Gary replied 2 months ago.

The P0101 is a MAF code.

Is the MAF secure, no leaks between the throttle body and the airbox?

The ABS codes are set in the PCM, or the ABS module?

Have you washed the engine bay recently, could be water entry at the ABS connector.

You need use up that fuel and get some fresh stuff in there, preferably 98.
