Component Testing

  1. With the turbocharger vane position control solenoid disconnected, measure for a resistance of less than 7 ohms across the solenoid terminals.
    • If the resistance is more than more than 7 ohms, replace the turbocharger vane position solenoid.
  2. Remove the vane position solenoid from the turbocharger. Reconnect the vane position control solenoid connector with the ignition ON. Depress and hold the cam follower slightly at the tip of the control solenoid valve. With a scan tool, command the control solenoid valve ON while observing the slot closest to the cam follower for the spool valve to move to the open position.
    • If the spool valve did not move to the open position and the circuits tested good, replace the turbocharger vane position solenoid.
