My 97 Corolla (engine 4A-FE) has the Check Engine Light on sometimes (code P0115). After 20 miles driving the temperature dial seems to be higher than what it should be (although still far away red danger zone).
I changed the engine coolant sensor 1 year ago, and the coolant fluid 6 months ago at a toyota dealer.
Don't know well the reason , but everything started a very windy day and some object might have hit something under the engine.
From the manual, P0115 might be the coolant temperature sensor or the wiring.
Any thoughts on what's going on? Why is the engine hot?

There may be a short in your engine coolant temperature sensor circuit, resulting in a higher temperature reading without the engine actually overheating.

P0115 diagnostic procedures are the same for 2ZZ-GE as for 4A-FE (page 36 and up).
Copy and paste entire link for it to work:
