VGT Position Sensor – Data Erratic, Intermittent, or Incorrect
|Fault Code: 1229
VGT Position Sensor – Data erratic, intermittent, or incorrect. Intermittent variable geometry turbocharger (VGT) position information is being received by the electronic control module (ECM).
Possible low power. Power to the turbocharger actuator will be limited.
Turbocharger Position Sensor Circuit
The turbocharger position sensor outputs a voltage signal to the ECM. The ECM converts this signal into a percentage value, 0 to 100 percent, indicating turbocharger position. A fully closed turbocharger actuataor is equivalent to 100 percent.
The turbocharger position sensor is located on the variable geometry turbocharger (VGT) actuator assembly. Refer to Procedure 100-002 for a detailed component location view.
This fault code is caused by an internal failure of the variable geometry turbocharger (VGT) position sensor. This failure causes erratic readings of variable geometry turbocharger (VGT) position.
