Is it possible to test the MAP sensor and Coolant Temp sensor? I seem to remember a post years ago about a way to test the Manifold Air Pressure sensor and Coolant Temperature sensor using an omn meter to test the continuity? Thank you all.

Nearly all MAP sensors will pass the ohmmeter test. Coolant temp sensor
should be about 2000 ohms or a little more. Only 2 ways I know of to really
test a MAPSensor:
1. Put the suspected sensor on a car that is running OK and see if it still
runs OK.
2. Replace it with a sensor you KNOW is good and see if it runs better or at
all.
