[Maleficio]

There are two coolant sensors above the thermostat housing. I've cleaned both sensor's terminals, but no joy. The light wasn't coming on until after a few minutes of driving, now it comes on at start-up and stays.

Gas mileage is dropping fast, and exhaust odor is getting bad.

I don't know which of those two coolant sensors I need to change, and the WSM doesn't seem to indicate which one. Any idea?

Thanks.
