2013 Ford Escape P0451 OBD2 Code: Causes, Fixes & Rain-Related Triggers

Model: 2013 Ford Escape Fault Code: P0451 Posted: 2017-11-07 08:40

My 2013 Ford Escape is throwing a P0451 diagnostic trouble code after I start the vehicle and shut it off within one minute. This issue appears consistently when the weather is wet or rainy. It has occurred three times so far, each time following a short drive cycle. The P0451 code indicates a problem with the evaporative emission control system, specifically related to the fuel vapor pressure sensor or the gas cap integrity. While I've searched online for solutions, most results are vague or outdated. I'm seeking reliable information on common causes and fixes for this specific fault in 2013 Ford Escape models, especially under wet conditions.

Check the gas cap first — a loose or faulty cap is one of the most common causes of P0451 in Ford Escape vehicles. Ensure it's properly sealed and tightened to the correct torque specification.

Always start with checking technical service bulletins (TSBs) for your 2013 Ford Escape, as Ford may have issued updates addressing P0451. If no TSBs are available, replace the gas cap and clear the code using an OBD2 scanner. A basic code reader is affordable and worth the investment — it helps avoid being overcharged by unqualified mechanics. I’d appreciate hearing how others resolve this issue. Thanks from South Africa!

I'm experiencing the same P0451 issue on my 2008 Ford Escape — it's particularly problematic at gas stations. Luckily, the Esso station I used had a rubber nozzle protector that prevented fuel spray. I've taken it to a local mechanic for inspection; hopefully, they can identify and fix the root cause. It seems like this issue has been around for years with no official recall from Ford. A side note: many 2013 Escape models show rust on the rear fenders — possibly related to environmental exposure or poor sealing. Finally found a place to discuss this — thank you all!
