OEM Engine Air Temp Sensor for 1996-2004 Nissan Pathfinder models. 

The engine air temperature (EAT) sensor, also known as the intake air temperature (IAT) sensor, is a component of the engine's fuel and ignition system that measures the temperature of the incoming air. This information is used by the engine control unit (ECU) to adjust the air-fuel mixture for optimal engine performance. Over time, the EAT sensor can become faulty or damaged and may need to be replaced.

Here are some signs that the engine air temperature sensor may need to be replaced:

• Check Engine Light: A malfunctioning EAT sensor can trigger the vehicle's check engine light to illuminate. This is often accompanied by a diagnostic trouble code (DTC) related to the EAT sensor.
• Poor Fuel Efficiency: A faulty EAT sensor can cause incorrect readings of the air temperature, leading to incorrect fuel calculations. This can result in decreased fuel efficiency and increased fuel consumption.
• Engine Performance Issues: Inaccurate readings from the EAT sensor can disrupt the air-fuel mixture, leading to engine performance issues such as rough idling, hesitation, or reduced power.
• Starting Problems: A malfunctioning EAT sensor can cause difficulties in starting the engine, particularly when the ambient temperature is cold.

Replace your insufficient Engine Air Temp Sensor with this genuine Nissan replacement part.
