Replaced my turbo, used my old VGT actuator which was in good shape. Installed it with insite passed calibration. After driving couple hours I keep getting a 2636 code stating abnormal update rate. Took it off and recalibrated again and same thing keeps happening. Is it a bad actuator or am I missing anything?
THANK ALL

Check the pins in the plug for dirt or corrosion. Make sure the female side pin is not spread to far out.

Check the connections. Make sure also that the wiring does not get close to the exhaust housing. it can get melted.
