Help With Code P006E

**Daviddotson** · 05-06-2023

Hello, I’m currently having issues with my newly rebuilt engine.

I have a compound turbo setup with an Aggressor 480 pushing my brand-new factory turbo.

I keep throwing a P006E Turbocharger supply voltage low.

I tested the voltage at the actuator and have 14.

I got that reading with grounding to the engine.

When I ground through the return ground on the harness, I only get 9 or 10 volts.

Is this normal?

I have cleaned all the grounds that I can find.

I’m stumped as to the next step of troubleshooting.

The exhaust brake works at random.

It doesn’t seem to stop while the trucks run down the road but only works at certain times of key on cycles.

I have deleted my Nox censor and grid heater.

I cut the harnesses and thoroughly capped all the wires.

Could this affect anything?

I have checked the connectors and wiring.

I haven’t gotten to the TIPM yet, however.

Any help is very much appreciated, guys.
