Wondering if anyone else had this problem. In 2021 had a code po451 fuel tank pressure sensor had dealer replace it $500 plus dollars. 1 year later code was back dealer replaced it under warranty. Again 1 year later code was back again replaced it under warranty. This year code was back called Ford of Canada to see if they would do anything and asked if they knew if there was a know problem with this sensor since they were only lasting 1 year they told me to bad they would not warranty it again.
A fuel tank pressure sensor that keeps dying after a year is frustrating. You’re not alone in dealing with this issue, but it’s definitely a bummer that Ford isn’t stepping up to fix the problem.
Have you tried reaching out to other Ford owners or joining online forums to see if anyone else has found a solution?
Sometimes, the community can offer valuable insights and workarounds. It might also be worth trying a different dealership to see if they have any luck diagnosing the root cause.
