Why replace the sensor until it has been proven defective? .. Normally a 'smoke test' will locate any leaks in the system then appropriate repair can commence.

I'm guessing they didn't look hard enough around a certain couple valves and solenoids under the car. Small leaks are super hard to find, they'll need to really REALLY look

Smoke test completed, they didn't find any leak. They replaced coolant temperature sensor and cleared code. Code came back within two days, I then replaced gas cap and rechecked code at Autozone. Thanks for replying.
