What causes turbo actuator to fail?

What causes turbo actuator to fail?

When the variable geometry mechanism sticks, it pulls a higher current through the motor than it is designed to take, this therefore causes the motor to burnout or the plastic worm gears to fail. This restriction can reduce boost pressure and can result in the vehicle being put into ‘limp home mode’.

Can I drive my truck with a bad turbo actuator?

Yep fine to drive, assuming no actual physical mechanical thing has gone wrong (which you’d definitely have known).

How does Ford’s variable geometry turbocharger work?

Ford’s variable geometry turbocharger allows one turbo to effectively take the place of two. At low RPM’s the vanes are configured to make the turbo spool up quickly to minimize lag, at higher RPM’s the vane angle is changed to perform like a larger turbo.

How does the Turbo actuator work on a Ford 6.0L?

On Ford 6.0L diesel engines, the turbo actuator (a.k.a. variable geometry turbo (VGT) control valve) controls the flow of exhaust gases through the turbo. When the actuator fails, the vanes can stick, causing the vehicle to lose power and generate too much or too little boost pressure.

How does the variable geometry system in a Ford VGT work?

At low RPM’s the vanes are configured to make the turbo spool up quickly to minimize lag, at higher RPM’s the vane angle is changed to perform like a larger turbo. The variable geometry system uses a PCM commanded electric solenoid to control the flow of pressurized engine oil which moves a piston to control the movement of the variable vanes.

When did Ford start using the VGT turbo?

Ford’s employment of the VGT was also a sign of things to come, as GM followed suit for the ’04.5 model year by introducing a variable geometry turbo on its LLY Duramax (the 6.6L V8 that succeeded the LB7). Then, with the unveiling of the 6.7L Cummins for the ’07.5 model year, Ram also made the switch to variable geometry technology.
