To test a VGT solenoid, measure the resistance across the VGT solenoid coil with a digital multimeter (remove the connector to expose two male pins). The resistance across the solenoid coil should be between 3.42 & 4.18 Ω when engine oil temperature (EOT) is at 73° F.
How do I know if my VGT actuator is bad?
- A flashing engine management light.
- Complete loss of power, causing the vehicle to enter limp mode.
- Intermittent low pressure.
- Low boost.
- Overboost.
- Noise from the turbocharger.
- ECU error symptoms control.
- Fault codes.
