Question
What causes coolant level sensor "intermittent" failures?
Answer
Floating mechanism sticking and electrical connection corrosion.
Explain
Intermittent failure causes random low coolant warnings. CHEPQ tools test sensor movement and clean connections—freeing the floating mechanism or replacing the sensor resolves the issue.
