Code P0452 Evaporative Emission Control Syst Pressure Sens/Switch Low Input on my 00 Blazer?

should I worry?Code P0452 Evaporative Emission Control Syst Pressure Sens/Switch Low Input on my 00 Blazer?
sounds like you have a leak in your evaporator emissions system, i would not be worried about the blazer shutting down, but i would go to auto zone have them read and reset the ses system ....if it ( the light ) comes back on after this reading i would have a tech check it out, it may be easy to fix and wont cost you to much..Code P0452 Evaporative Emission Control Syst Pressure Sens/Switch Low Input on my 00 Blazer?
P0452





CIRCUIT DESCRIPTION


The Powertrain Control Module (PCM) monitors the Fuel Tank Pressure (FTP) sensor signal in order to detect vacuum decay and excess vacuum during the enhanced Evaporative Emission (EVAP) diagnostic. The PCM supplies a 5-volt reference and ground to the sensor. The FTP sensor signal voltage increases when the fuel tank pressure decreases. Negative pressure or vacuum indicates high voltage. The FTP sensor signal voltage decreases when the fuel tank pressure increases. Positive pressure indicates low voltage. This DTC sets when the FTP sensor signal goes below a predetermined value.





In my state, you will not pass the emission station with a trouble code.
no it will run ok try cleaning the connection may be dirty or weak ground.
