Hello there,

P0172, P0175 are rich both banks.

U0121 is lost communication with ABS.

Any mods above what HSV does?

I have a scan tool if I case you want to know some valued the sensors
Chevy Mechanic: Gary, ASE Certified Technician replied 1 year ago

Are the codes current or history?

Does it start normally?

How often does this car get driven?

Can you look at STFT and LTFT data, and post some figures here?

The abs works great for a few KM then the Abs fault comes on

VE has issues with low battery faults, which log codes straight after startup.

How old is the fuel?

For the ABS error coming is U2100 / U0140/U0100
Customer reply replied 1 year ago
Now fault P0172 and P0175 is gone but P0101appear
Chevy Mechanic: Gary, ASE Certified Technician replied 1 year 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.
