I need to know what the diagnostic code PO1448 means? thank you


Well it's not a p0 code which indicates a generic trouble code, this is a code p1448 which is a manufacturers specific code, and your stands for a bad manufacturer controlled auxiliary emissions controlled component. Try checking your charcoal canister which filters fuel vapors from your gas tank, there is an evap vent control valve which can get stuck in position. You can replace that valve or try cleaning it with some carb cleaner and then using a small screwdriver to free the plunger up. Your check engine light will go off after a couple drive cycles without a fault or you can reset it iwth a code scanner.

p1494 code indicates a fault was detected in the LDP (leak detection pump) that is part of the EVAP system. You most likely have a defective pump switch. This area of the emission system can sometimes be very difficult to diagnose, but usually the fault can be corrected by replacing the switch.
