My MM3 tuner just showed these two codes associated with a check engine light that I have.
I also noticed that I don't have any engine brake.
I've been reading that this might be an actuator?
The truck has about 190,000 mi on it and has never had any turbo-related service to my knowledge.
Any suggestions on how to begin troubleshooting this?
I'm hoping it's something that I can fix myself and not having to replace a turbo or something ridiculous like that.
