Code P0500 2005 Infiniti G35 Description

The P0500 diagnostic trouble code (DTC) in a 2005 Infiniti G35 refers to an issue with the Vehicle Speed Sensor (VSS). The VSS is a crucial component that monitors the speed of the vehicle and sends this data to the engine control module (ECM) to assist in various functions such as fuel injection, ignition timing, and transmission shifting. When the ECM detects a discrepancy in the VSS signal or a complete lack of signal, it triggers the P0500 code.
