Ecm temp sensor
Good quality sensor but not the sensor I needed to repair the dash on my 1991GMCK 1500. This is the sensor that controls the ECM and works on fuel injection.

Temp Gauge Is Alive Again!
This ACDelco coolant sender works flawlessly and tells an accurate temperature on the gauge. This should not be mistaken with the coolant sensor which is on the too of the block. This sender is on the side of the engine block.

Does not work properly in a 94 4.3L v6
There’s nothing wrong with the sensor, and it does fit and plug in. But apparently GM used a different resistance in the 1994 Chevy trucks with a 4.3l V6. The sensor works, the gauge works. But it reads very low. Like 110-120° instead of the 190-200° that the water temp really is. Very annoying for me, but nothing inherently wrong with the sensor.
