Help!!! The check engine light just came on in my 2005 EX Accord with 54,000 miles. I took it right to Auto zone and had them pull the code. The code P2185 came up and the guy's hand held code reader said that it happened twice and that the coolant temperature sensor was bad.

So 3 questions:

1. Can I still drive it to work (74 miles each way)?
2. Is this easy to fix?
3. Could something else be causing this code?

Thanks
