Check Engine Light came on.

[410225]

On the way home, I got Check Engine Light on. Pulled the code with my trusty HF code reader and it reads "0116" which interprepts to Coolant circulation problem. What does that mean? I have checked my coolant and it is full.

it thinks that after 2 20 minute drives your coolant is to cold. Where do you live? If in a cold area possibly a bad thermostat which is stuck open or a bad temp sensor if the guage is reading low. The truck needs to think it is above 95 deg F to avoid this code.
