Challenger Posted February 11, 2014 Share Posted February 11, 2014 Mid 128 Sid 27 Fmi 9 Turbo actuator. abnormal updateNo turbo, no power.You probably have a bad actuator. When looking at your turbo the actuator is the square box bolted to the side with 4 allen head bolts. There were some problems with the connectors fretting, which makes your terminals greenish and dusty. Normally we would check the connector and remove the actuator to check the turbo lever movement. If the lever sticks or doesnt move a complete stroke the complete turbo would need replaced. But if the lever moves, replace the actuator, calibrate the turbo and road test.
