Question

Quizplus · Accepted Answer

Using an ohmmeter to test a sensor, especially one that might be sensitive to the current used in such tests, can damage the sensor. Sensors like the O₂ are often designed to operate within specific electrical parameters, and the introduction of external currents for testing purposes can lead to inaccurate results or damage.
