Help low boost

[gearhead]

voltage to actuator signal voltage can read 0 on alot of them, but the position meatured must match commanded.

Those are all normal.

Ok so those are unrelated. Does it sound like a bad actuator?

Try doing turbo test see what happens.

Ok so my commanded actuator position is always on 5% . It does not move up or down no matter what position the throttle is in. If the actuator went bad would the ecm command as normal?

What is the turbo test?

[gearhead]

IN insite there is turbo test or hysteris test to make sure turbo is working or calibrated.

[gonzo1949]

OK gonna check

The only one I see is the calibration test

[gearhead]

ok try the calibration last test for after actuator is installed.
