Known Problems

The Honda Pilot, 2WD and AWD models, commonly have problems with the EVAP canister vent solenoid. It stops responding to commands to open and close, and the following occurs:

  • Illumination of the check engine light
  • OBD trouble code P1457 is stored
  • Engine takes longer than usual to start
  • Fuel mileage decreases noticeably
  • The valve is located on the charcoal canister, and is meant to open and close upon command. It fails due to corrosion breaking one of two internal seals, which allows air to escape the system, signaling the OBD trouble code P1457.

    Correcting the problem can be done by replacing the vent valve, or, in some cases, cleaning and resealing the vent valve has been successful. You can get an estimate for this repair here.

    A worn, missing, or loose gas cap can cause the same issues.

    The exhaust recirculation valve (EGR) on the 2003-2017 Honda Pilot may fail, causing:

  • Illumination of the check engine light
  • OBD trouble codes P0401 and P1491
  • Illumination of the "VTR-4" light
  • Rough idle
  • Reduced fuel economy
  • Engine vibrations
  • Hesitation or stalling
  • Long cranking before engine starts
  • Failure of state or federal smog tests
  • The EGR valve has open and closed positions, and opens or closes on command from the computer.

    Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.

    To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

    Map light will not turn on when opening drivers or passengers door. Caused by a faulty door switch. Requires replacement of door switch on side of non operation.

    The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.

    An overheated wire in the head light harness can cause the low beams not to work. Replacing combination light/turn signal switch switch, the wire for the low beams, and the combination switch connector (if damaged) should repair this issue.

    On certain models a leaking side marker light wire harness can cause a water leak inside the vehicle. Resealing the wire harness where it goes through the body into the cabin area should stop the leak.

    Carbon build up on the throttle body can cause a sticking throttle. Cleaning the throttle body will commonly repair this issue.

    On certain models the PCM misinterprets data from the coolant sensor and sets a false Check Engine light (MIL). A software update from Honda will repair this issue.

    A knock or clunk type noise may be noted from the front suspension over bumps. This is can caused by worm stabilizer (sway) bar links. Replacing both stabilizer bar links will commonly repair this issue.

    Noise and judder can develop from the rear axle due to differential fluid breakdown. Replacing the fluid will commonly correct this issue.

    The engine may develop and oil leak due to a porous engine block casting. The repair procedure is dependent on where the leak is located. Honda has released a service bulletin covering model year 2003. Honda may offer assistance with repairs, determined on a case by case basis.

    A rough idle and harsh transmission shift can be caused by a broken front engine mount. Replacing the broken mount will address these issues.

    A chirp noise from the timing belt area can be caused by a tilted idler pulley. Installing a corrective shim from Honda will commonly correct this issue.
