Land Cruiser 200 Series V8 1VD-FTV Turbo Actuator Stepper Motor Problems & Solutions
Best Stepper Motor Replacement Solution:
The Toyota V8 200 Series Land Cruisers run Left side and Right side turbochargers. These turbos have electronically-managed variable vane / geometry technology (VNT). As such, there is no ‘dump’ valve with a vacuum or pneumatic wastegate controller. Instead, a stepper motor or electric actuator does the job of actuating the vanes.
The ‘motor’ changes vane angles inside the turbo to affect boost control.
And here is a secret to the Land Cruiser 200 Series V8 1VD-FTV Turbo Actuator Stepper Motor Problems and Solutions:
This Stepper Motor is a separate component from the turbochargers, and can be replaced without replacing the entire turbo.
If there is a general boosting issue, it may only be a faulty Stepper Motor causing the problem.
Often this is associated with the computer forcing limp mode onto the engine, and /or a warning lamp for ‘engine’ comes on.
And rev range may be limited to below 1500 rpm as a result.
If this happens, check for physical problems or symptoms apparent in the turbo.
Look for excess movement in the compressor(impeller) wheel (indicating wear with high pitch noise as a result) or oil leaks.
If none of the above are apparent, it is more likely to be the stepper motor / actuator only.
Stepper Motor Replacement – Check First
At such times, its a good idea to scan the vehicle with a scan tool.
Doing so can confirm if a code related to the Stepper / Actuator fault has been ‘thrown’.
A typical code looks something like this: P1251(34)-Turbo stepper motor circuit(intermittent).
Most often the turbocharger OR just the stepper motor are at fault, not both at once.
If a Stepper Motor issue is confirmed, you can just replace the faulty component.
It doesn’t make sense to pay for an entirely new turbocharger(with Stepper Motor), if just the electronic stepper needs replacing.
In the recent past, you were only able to purchase complete turbo units with actuator attached.
This is expensive and no is longer the cased.
Below is a quick solution (entire turbo can remain on the vehicle) AND a solution that can save several thousand dollars!
Purchase and replace the stepper motor only!
