Code P0182 2003 Nissan Sentra Description

The P0182 code on a 2003 Nissan Sentra indicates a problem with the Fuel Temperature Sensor Circuit, specifically a low input signal being detected. The fuel temperature sensor is responsible for measuring the temperature of the fuel in the fuel tank. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the sensor detects a low input signal, it means that the fuel temperature is lower than expected, which can lead to issues with the fuel system's efficiency and performance.
