Question
How to diagnose faulty coolant level sensor in cooling systems?
Answer
Monitor sensor resistance and test for continuity at different levels.
Explain
A faulty coolant level sensor fails to alert low coolant. CHEPQ multimeters test sensor resistance (varies with level) and continuity—replacing the sensor ensures driver warnings for low coolant, preventing overheating.
