Has anyone seen this before? I cleared it once and it came back after a few days. I really cannot believe this thing is throwing a CEL already. The dealer cannot get me a loaner until next week.

P0451 - Evaporative Emission System Pressure Sensor/Switch Range/Performance
Description: This DTC sets when a fuel tank pressure (FTP) sensor range (offset) concern is detected. The FTP sensor output is offset by greater than 1.7 inches of water or less than -1.7 inches of water.
Possible Causes:

• Intermittent open in the FTP sensor
• Intermittent short in the FTP sensor
• Intermittent open FTP circuit
• Intermittent short FTP circuit
• Contaminated FTP sensor
• Damaged FTP sensor
• Damaged PCM

I am sure the dealer will fix it just fine.

Thanks for the quick response.

Verdict was the fuel pressure vapor sensor was bad and they replaced it. Everything seems good now!
