I just replaced the fuel pump and filler neck grommet On my 2000 Mustang GT 4.6 liter .Now I'm getting a p0453 evap pressure sensor is indicating a higher than normal pressure. I found the plug at the back of the fuel tank and cleaned the pins on the plug but I'm still getting the code. What else can I try?

While working on your car have you ever wanted: to find an ODB2 operational PID value (say fuel pressure or MAF)? How about graph a PID value over time? Or compare multiple PID's over time? Access a bi-directional PCM control such as test a...
