The fuel tank pressure sensor is critical to monitoring fuel vapor and managing emissions. Emission issues: The FTP sensor is a vital part of the EVAP system, so if it malfunctions, it can fail to detect vapor leaks. The vehicle will likely fail an emissions test since the EVAP system captures and controls fuel vapors.
