ECT sensor ohms test
I just got one trouble code 116, the engine was running and engine was hot. It's maybe a bad ect sensor. Engine runs rich, hard to start.
I ohms tested the sensor engine was not started and got over 200,000 oms. it was 32 degrees outside. I retested tested sensor when hot, about 140 degrees and I got 100,000 ohms.
Does this mean (100%) that my sensor is bad?

Yes, I would say the ECT is bad. Reference the values indicated here: Ford Fuel Injection Engine Coolant Temperature Sensor (ECT)
