Engine Error Code??

[Skrimz]

I am getting an error code P0450. Has anyone ever seen this engine error code or know what is causing it. did some research, super vague code, not a lose gas cap, no obvious leak but not sure. any other ideas?

From my 2001 FSM; "Open or short in vapor pressure sensor circuit"
"Vapor pressure sensor"
"ECM"

I have attached scans of the FSM troubleshooting pages.

Good Luck,

Bob

Resolved by replacing vapor pressure sensor with an OEM used one off ebay. :tea:
