Do you need a harness for a Duramax Turbo vane sensor?

Do you need a harness for a Duramax Turbo vane sensor?

Please note that due to a GM design change, 2004.5 – 2005 LLY models will require a wire harness adapter to plug this sensor into your original harness. The wiring harness adapter is included with each sensor sold.

Why does my Duramax engine have low power?

This sensor is a common weak point on the Duramax engines. When it fails the engine computer is no longer able to keep track of the position of the variable geometry turbo. Depending on which position the turbo vanes are stuck in, you may experience low power either at the low or high end of the RPM range.

Why is my Turbo sensor stuck in one position?

Black smoke and turbo position sensor codes are other common symptoms. However, it is highly advised to pursue a careful diagnostic strategy before replacing this part rather than replacing it based on symptoms alone. Another common problem is that the variable vanes could also be physically stuck in one position.

Can you change the sensor on a turbo Vane?

Click to expand… Technically, yes, that is correct but in practice you probably wouldn’t see much difference if you just removed and cleaned the same sensor. If you replaced that with a brand new sensor, the mapping may be slightly different and you should definitely use a Tech 2 to recalibrate the ECM for the different sensor.
