Code P0182 2002 Nissan Altima Sedan Description

The P0182 diagnostic trouble code (DTC) for a 2002 Nissan Altima Sedan indicates a problem with the Fuel Temperature Sensor Circuit, specifically a low input signal. 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 fuel mixture and ignition timing to optimize engine performance and fuel efficiency. When the ECM detects a low input signal from the fuel temperature sensor, it may not be able to accurately adjust the fuel mixture, leading to potential drivability issues.
