Is it this sensor?

Timing Chain Temp Sensors
This sensor measures the temperature at the engine's timing chain cover on the left side. Interestingly enough, this switch also has positive current going to it, which makes it act as a small heating element as well. It only stays powered during cranking and the heating element signals it to stop sending power to the cold-start valve if the engine does not start after much cranking -- to avoid flooding the engine.
