Variable Geometry Turbo (VGT) Actuator Position Sensor Circuit
on 2007 Dodge Ram 2500 5.9L I6 Cummins Diesel · 4WD
What this code means
The variable geometry turbo vane position sensor is reporting values outside the expected range. The VGT system uses movable vanes to optimize boost across the RPM range.
Symptoms
- Check Engine Light
- Poor low-end torque
- Excessive smoke at low RPM
- Turbo surge or flutter
- Reduced fuel economy
Common causes
- VGT position sensor failure
- Carbon buildup on vane mechanism
- Actuator motor failure
- Corroded sensor connector
- Damaged wiring harness
Diagnostic steps
- Read VGT position PID on scan tool
- Command VGT vanes through full range with scan tool
- Inspect VGT actuator connector
- Test position sensor voltage range
- Check for carbon restriction on vanes
Repair notes
Replace VGT position sensor or actuator assembly. Clean carbon deposits from vane mechanism. Common on diesel vehicles.
