Fuel Tank Vacuum Pressure at Gary Matthews blog

Fuel Tank Vacuum Pressure. You can troubleshoot it by spraying. The p1450 code indicates that there’s too much vacuum in the evap system or fuel tank. Vented gas caps help prevent vacuum lock, a condition where the pressure inside the fuel tank becomes. If the high vacuum remains for longer than sixty seconds, the pcm detects a fault. Gas has a relatively high vapor pressure, which means it tends to vaporize easily and even builds up a pressure when enclosed in. If the fuel filler cap is stuck, it can prevent the excessive fuel tank vacuum relief from happening, which will cause the p1450 code. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. This situation means the pcm cannot bleed the vacuum to maintain proper pressure. A fuel tank pressure test and gas cap pressure tester are diagnostic procedures that check the ability of your fuel tank or gas cap to hold pressure.
