Known Problems

There have been some issues reported with the electric sliding doors. Our technicians remind us that proper diagnoses will be necessary to determine the cause of various faults which may occur.

Third row seat latch cables can come loose from the handle and can prevent the seat from unlatching. Reinstalling the cables and retaining them with clips should correct this issue.

The Honda Odyssey may develop issues with the automatic transmission.

Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.

If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.

In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.

The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.

The Honda Odyssey may have issues with the idle air control system, causing:

The idle air bypass system is made up of vacuum lines, an idle air control valve (IACV), the throttle body, and intake manifold, and allows enough air into the engine to idle when the throttle body is closed. The OBD trouble code P0505 refers to this system to inspect for failures.

The most likely cause is a dirty or failed IACV, but vacuum lines, intake manifold gasket, throttle body gasket, and IACV gasket should be inspected.

In all cases involving the IACV, the throttle body ports should be cleaned prior to installing the IACV onto the throttle body.

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.

There have been reports of Catalytic Converter failure that causes the Check Engine light to come on. Replacing the catalytic converter will repair this issue.

The 1999-2016 Honda Odyssey may 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 1999-2016 Honda Odyssey V6 may fail, causing:

  • Illumination of thecheck engine light
  • OBD trouble codes P0401 and P1491
  • 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.

    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 years 1999-2003. Honda may offer assistance with repairs, determined on a case by case basis.

     

    Manual sliding doors will stick or not open easily due to the door seal sealing too well. Sometimes this can cause the door handle to break when trying to open the door. Replacing the door seal with an updated seal 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.

    On certain models the rear brakes can groan when coming to a stop. Replacing the rear brake drums may be necessary to correct this issue.

    Certain models in colder climates can exhibit a Check Engine light (MIL) when moisture freezes in the Manifold Absolute Pressure (MAP) sensor. Replacing the MAP sensor repairs this issue

    A buzzing noise at freeway speeds can be caused by the engine and transmission resonating through the transmission shift cable. The Power Control Module (PCM) must be replaced to stop the resonating noise. 

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