Was the engine warmed up before you pulled the codes?

You didn't answer my question. When you read the codes, was the engine warmed up, or was it cold?

Then you need to replace your ECT (Engine Coolant Temp) sensor, reset the ECM, and run for codes again. Odds are that a new ECT will solve your problems.
Take care, ~Chris
