How to Test a Pressure Sensor | It Still Runs

Use a multimeter or voltmeter to test the wiring and electrical connection leading to the sensors. Disconnect the electrical connection and touch the probes of the multimeter to the car's electrical harness. Turn on the engine and turn the multimeter to its voltage setting. Different sensors will have different voltage readings, however, if you do not detect any voltage coming from the vehicle's electrical system, then the wiring may need replacing. As an example, the MAP sensor …
