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
