2009 Dodge Ram 1500 Question: P2181 code + engine starting trouble

P2181 code. VIC reading for the cooling shows normal op. temp. 194- 200. sometimes it shows nothing and a code pops P 2181. Several times I've had engine starting problems. The engine cranks several times I turn the key off retry after cranking several more times it starts. Under the VIC I get a red Z type error with back word parenthesis’. The code remains P2181 Please help -

I figure the P2181 is going to be a sensor. I've watched the temp for several days and it's been excellent. I'm just not sure about the not starting, it has a tip switch not a key. I've just come back from driving it and made several stops and restarted it with no problem at all. Confusing too say the least. -

Did you ever figure this out. Sounds like the exact same issue I'm having -
