Code P004B

Hi
i have a2012, 200 series Landcruiser that came up with a code P004B.

Both stepper motors were replaced, two weeks later code P2564 came up, this was a loose wire on left Stepper motor.

two days later P004B reappeared. Cleaned plugs on turbo drive motors that are in front of right hand front tyre. Unplugged top wires and swapped with bottom wires, to see if a different code came up as P004B relates to left turbo.

Today the same code came up P004B. Mechanic is at a loss and I’m 6k down the rabbit hole with no solution. Turbos were apparently checked and ruled out as the problem.

should I just replace the drive motors or could there be another problem,

 

regards Davo
