Temperature monitoring: Measures engine operating temperature and reports it to the engine control module.
Engine management input: That signal helps the ECM manage fuel delivery, ignition timing, and cooling-fan operation.
Dual part type: Listed as both an Engine Coolant Temperature Sensor and an Engine Cylinder Head Temperature Sensor.
Signs this sensor may need replacing include an erratic or inaccurate temperature gauge, hard cold starts, fan behavior that seems off, or a stored temperature-related trouble code. Because these symptoms can have other causes, diagnose the fault first; if a failed sensor is the cause, this unit replaces it. One sensor is used per listed application (qty 1). Manufacturer part number TS-640.
