What P0174 Means on Your TOYOTA HIGHLANDER

Real TOYOTA HIGHLANDER Owner Reports (Source: NHTSA Complaints Database)

"Today (8/26/2025) my wife experienced the engine light kicked on and that the AWD system needed to be checked. After fueling up it made knocking noises and difficulty starting, and took two times to start up. Ran an OBD scan and this is what it says, which is related to fuel pump low pressure."

What To Do Next

  1. 1
    Check for recalls on YOUR VIN

    Go to nhtsa.gov/recalls and enter your VIN. Free repairs if your vehicle is covered.

  2. 2
    Get a proper diagnosis

    A code alone doesn't tell you the exact failed part. A diagnostic at a shop ($50-$150) pinpoints the root cause before you spend money on parts.

  3. 3
    Compare repair quotes

    Get 2-3 quotes. Dealer vs independent shop prices often differ 30-50% for the same repair.
