These codes are related to the turbo vain position sensor, my question is how do I test to see if it is the sensor or the turbo its self? It is going to suck to buy a 400.00 sensor and find out it was the turbo. If i unplug and clean the sensor no change still runs like crap.

 

where is the sensor located ?

 

It comes out of the top of the turbo and mounts between the #4 and #6 injectors.
