The coolant temp sensor is on the front of the engine just to the left of the thermostat housing and above the idle pulley. The MAP sensor is just to the left of the coolant sensor. When you turn the ignition on engine not running the MAP sensor should give you atmospheric pressure 14.7 PSI ( 29.9 inHG). And it should be steady, When you start the engine the MAP should follow vacuum steady and not be fluctuating ( give or take about 1 inHG) so at idle the MAP will be about 10 inHG ( 29.9 - vacuum about 20 inHG at idle) as speed increases the vacuum decrease and the MAP should increase steadily not be jumping all over the place. Same with your MAF readings. AS MAF increases MAP decreases.
Water coolant temperature should act normally, increasing as from cold to warm then steady at the upper limit as your care warms. If you see fluctuations that don't make sense replace the sensor.
