Axe 'Em

I posed earlier about my problems with the truck dying in the post titles "Intermittent check engine light....." Not sure why but it won't let me post a response to that thread so I'm starting a new one.

I was finally able to get the code to display but am not sure i am reading it correctly. The code appears to be I.I...I.I which is about a second delay between the first two flashes, then a 2.5 second delay, then about a second delay between the second two flashes.

This would appear to be 22, and if so would mean the the water temp sensor is faulty. Does this make sense to anyone? Thanks again for the help.
