ECT Sensor

I had the codes read at AutoZone. Only two codes came up, one regarding the ECT sensor and one regarding fuel air something or other. The guy told me to make sure the gas cap was on tight. ECT sensor a major thing? Another question: Is there another test where the mechanic hooks up a computer for a more detailed reading?

We're not very good with the codes ... and we're absolutely worthless without them.

Please go back and get the exact codes, they both will be 5 character alpha-numeric... "P1116" for example.

If you need to change out the Engine Coolant Temperature sensor, that's about as easy as it gets.
