Code P0182 2002 Nissan Sentra Description

The P0182 diagnostic trouble code (DTC) for a 2002 Nissan Sentra indicates a problem with the Fuel Temperature Sensor Circuit, specifically a low input signal. The fuel temperature sensor is responsible for monitoring 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 and ignition timing for optimal performance and efficiency. When the ECM detects a low input signal from the fuel temperature sensor, it may cause issues with fuel delivery, combustion, and overall engine performance.
