UPDATE… I put a new actuator on and the check engine light immediately went away and it’s back to no codes, active or inactive.

Also Rawze, the old actuator had a RX part number so it wasn’t original. But it had been on the turbo a long time.

Thanks for the update.

Now .. you need to find out what caused that terminating resistor to fail like that. Things like ...

** Someone using high-power (cb or ham) radio gear that is not grounded properly?.

** Alternator noise is higher than normal due to leaky/weak diodes internally?.

** One of those crappy square-wave, or modified-sine-wave truck stop Power inverters?.

-== You get the picture.
