SENSOR - ENGINE COOL TEMP (Nissan NI2263071L00)

NI2263071L00: A failing engine coolant temperature sensor can cause hard starting, poor fuel economy, or an illuminated check engine light. This aftermarket replacement part references Nissan catalog number NI2263071L00. The sensor monitors coolant temperature and sends a signal to the engine control unit. When the sensor fails, the engine may run rich or lean, leading to increased emissions. Over time, thermal cycling can degrade the sensor's internal thermistor, causing inaccurate readings. Verify the serial number or application, then call (562) 693-7748. The sensor is a threaded probe that directly contacts the coolant passage.
