Temp gauge acting funny and van surging

hi
we live/drive on dirt roads. lots of shaking. '00 astro van started slightly hesitating and the temp gauge would drop. temp gauge would come back to normal and van would run as it should. on pavement it runs ok until a rough spot.

now the temp gauge shows no temp. van seems to run fine.

noticed some sort of sensor on the driver's side of the upper coolant hose and thermostat housing. ideas what the senor might be?

is the temp sensor on driver's side of engine block?

thanks

dick
