cat 22-11 code help

Possibly bad crank damper not absorbing the harmonics causing the rattling sound you are talking about under load. I had a mack etech with a code for erratic timing sensor after replacing sensor and checking everything else i put a balancer on it and it cured it. The crank broke six months later.

 

What was the outcome and fix to your problem?

 

Having same issues.

 

Did you ever find what the problem was?

 

you ever found out what the problem was? I know this is a really old post but I'm having the exact same issue with my truck

 

I know this entire thread is about 14 years old. And your post is about 5 years old. But did you ever figure out a result? I’m having the same problem.
