Common Bad Symptoms
When this component begins to fail, you might experience several warning signs. Common symptoms of a faulty Engine Coolant Temperature Sensor include an illuminated check engine light (CEL) with diagnostic codes like P0117 or P0118, the dashboard temperature gauge behaving erratically or dropping to zero, the engine cooling fans running constantly at high speed as a safety fail-safe, a noticeable drop in fuel economy, or a rough idle and hard-starting condition when the engine is completely cold.
Safety First!
Before you start working on your vehicle, always prioritize safety. Never attempt to remove this sensor while the engine is hot, as the cooling system is under high pressure and can cause severe burns. Always wear proper eye protection and mechanics’ gloves, allow the engine to cool down completely, and ensure your working environment is safe before performing any vehicle maintenance.
