The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as ...

The fuel tank pressure sensor measures positive and negative pressure in the fuel tank. During EVAP monitoring, the PCM uses this pressure to detect vapor leakages in the fuel tank and will trigger a ...

If fuel pressure seems to be good, it’s time to connect a scan tool and check for fault codes. If a fault that could affect the fuel system is present, you’ll need to address it at this time.

In this scenario, the fuel could block the recirculation line and result in fuel tank pressure sensor readings issues.

When it happens, the fuel could block the recirculation line and result in fuel tank pressure sensor reading issues.
