Need help with code
My car had a Code P 0455 and I can't find any information regarding this code. Does anyone know what the problem is or if it is serious? Thanks for your help, Dave

The control module tests the Evaporative Emission (EVAP) System for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP canister vent solenoid valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or the vacuum level decreases too rapidly, this DTC sets.
The following table illustrates the relationship between the ON and OFF states, and the OPEN or CLOSED states of the EVAP canister purge and vent solenoid valves.
Let me know if you need the whole document if the gas cap is not the issue.

Nice job Rich!

It seems that the gas cap was the problem (I know I tightened the cap tighter than that). Thanks for your help. Everyone on this forum has been so helpful when questions arise. Thanks again, Dave
