Where is turbo vane position sensor?
Locate the vane position sensor atop the turbocharger center section to the driver side of the turbo oil feed line.
What does a turbo vane position sensor do?
The Turbo Vane Position Sensor is what allows your diesels ECU/ECM unit to properly control the variable geometry turbo vanes on your turbo.
What is Vpos Duramax?
The VPOS is the ECM’s way of regulating the boost PSI. It eliminates the use of a waste gate. If you need more boost at a certain RPM the vanes will close more therefore allowing for faster exhaust gasses therefore spinning the turbine more therefore more boost!
What is P2563 Duramax?
P2563 is an OBD-II generic code. The engine control module (ECM) monitors the variable geometry turbocharger electronic actuator. This code indicates that the ECM has detected a problem with the variable vane geometry turbo control.
How do you clean a turbo vane sensor?
Percieved vane sticking might actually be caused from a bad vane position sensor. The easiest way to clean out the turbo vanes is to floor the go pedal and blow it out….work it and get it hot! I do this at least once a day to make sure it stays clean.
Where is the turbo boost sensor on a Duramax?
This is your Boost sensor. The manifold pressure sensor is located in the intake manifold and measures pressure delivered by the turbocharger. It is a three wire sensor that provides an analog voltage signal.
How do I know if my turbo is bad on my Duramax?
Signs of a Bad Turbocharger
- Too Much Exhaust Smoke. If the casing of your turbocharger cracks or if some internal seals are worn out, it could cause the oil to leak into your exhaust.
- Loss of Power.
- Increased Oil Consumption.
- Loud Siren Noise.
- Check Engine Warning Lights.
- The Boost Gauge.
How can you tell the difference between LLY and LBZ Duramax?
The ’06 LLY is much quieter than the ’05. The ’06 LLY and LBZ have the same turbo (ask McRat, he put one on his ’05 LLY). It has the reduced compression, meaning that it has the LBZ pistons. If the LBZ piston has an increased wristpin diameter, then it stands to reason that the ’06 LLY also has the LBZ rods.
How do I fix my Duramax P2563 code?
Replacement Options
- Pull the vane sensor and clean it along with the wiring (requires this special removal tool)
- Pull the turbocharger and clean the internal components like the unison ring.
- Run scan tests and VGT Learn tests to determine what is at fault.
- Replace the sensor or the turbo (depending on which is at fault)
