The CEL came on last week and involved codes 19 & 22. I was told in the other post that code 22 was crank-shaft not cam-shaft. While working on code 19 solution I was finally able to clear the codes and the CEL went off.

I asked if the above codes were all related, but it was not clear. If the codes 19 & 22 are not related, then I want to find out if I need to address code 22 by replacing a sensor - but which one?

The car seems to run good, smooth acceleration and idle. I am not sure why either of these codes came up.
