I have received this code 3 times, 2 times it came on after driving 40 minutes and turned it off for maybe 5 minutes, upon startup the check engine light came on. I don't remember how the other one came on.
I changed the spark plugs and cobs, spark plugs weren't tightened properly. The light still came on. I read some posts that there are two bolts on top of the timing chain area that might be loose. I wonder if this might be the problem or any other suggestions. I also took the dipstick out while running and have vacuum at least that what somebody's post stated.
Do you
have the same problem?

Good evening,

This code sets when there is a noise as it measures harmonics.

I attached the description and the procedure for replacing it if it needs it.
