Code P0183 2005 Infiniti G35 Description

The P0183 code on a 2005 Infiniti G35 indicates a problem with the fuel temperature sensor circuit registering a high input. The fuel temperature sensor is an important component in the vehicle's fuel system, responsible for monitoring the temperature of the fuel in the tank. This information is crucial for the engine control module (ECM) to adjust fuel delivery and optimize engine performance. When the sensor detects a high input, it means that the temperature reading is outside of the expected range, potentially leading to incorrect fuel calculations and affecting the engine's performance.
