Known Problems

The Honda Accord 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 you 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 Honda Fit is known for sudden, poor drivability issues, as soon as 50,000 miles, such as:

  • Loss of power 
  • Engine Stalling 
  • Stuttering at highway speed 
  • Check engine light intermittent or flashing
  • "D4" light on intermittently or flashing 
  • OBD trouble code(s) P0300, P0301, P0302, P0303, and/or P0304
  • One or more ignition coils may fail unexpectedly, even though the code may clear.

    The coil packs will cause engine misfires during normal operation, and must be replaced to ensure engine performance.

    Cleaning and applying dielectric grease may help in very few cases.

    The 1998-2016 Honda Accord 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 2006-2014 Honda Ridgeline 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.

    The 1990-2005 Honda Civic commonly have issues with radiator leaks due to normal operation. The leak usually starts small with the engine running slightly warmer than normal, but may/will eventually cause:

  • Coolant puddling under vehicle
  • Engine overheating
  • Unexplained coolant loss (only at first)
  • Vehicle in “limp mode”; loss of power
  • Cylinder head or head gasket failure
  • The coolant leaking can have a severe effect on your vehicle if left in disrepair. If the radiator is diagnosed as the leaky part, it will need to be replaced, or resealed if that is an option.

    Note: coolant is toxic to animals, but tastes sweet. Any coolant spills should be cleaned to protect animals and children.

    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.

    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 1998-2003. Honda may offer assistance with repairs, determined on a case by case basis.

    A sticking intake manifold runner solenoid can cause the Check Engine light (MIL) to illuminate. Replacing the solenoid will repair the issue.

    The Honda Ridgeline, from 2006-2014, commonly has 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.

    Worn door locks (tumblers) can cause the lock not to work. Removing the lock and replacing the worn parts (tumblers) is needed to get the lock working again.

    On Certain models a faulty power window switch can cause the power windows to work or not work intermittently.

    Damaged engine mounts can lead to vibration and roughness felt in the steering wheel. A rattle in the dash and engine area may also be heard. Replacement of damaged mounts will commonly correct these issues.

    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.
