Known Problems

The PCM can misinterpret misfire data and set a false Check Engine (MIL) light requiring a PCM update to repair.

The driver's door latch assembly can break internally, which causes the door to stay closed. The interior and exterior door handles do not work to open the door. Our technicians note that the door panel must be removed while the door is closed (likely damage will occur) and the latch assembly must be drilled in a specific spot for the door to open.

Ignition switch failure may cause the car to stall or fail to start. Honda issued a recall to replace the ignition switch. For more information on this recall please click here»

Power door locks can activate intermittently due to a faulty door lock actuator in the driver's door.

Excessive oil consumption can cause a low oil level condition, which can result in illumination of the Check Engine Light.

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 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 1990-2016 Honda Accord engine oil pressure sensor may leak from normal operation.

More information about the oil pressure sensor here.

To correct the leak, the sensor must be inspected, properly sealed and installed, or replaced with new.

The 1997-2017 Honda Accord 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 2013-2012 Honda Accord has brake caliper issues, which are known for causing vibration and grinding noises at all times.

    The brake rotor is a disk that sits between two brake pads. The brake pads are squeezed against the disk by what is called a brake caliper. When that caliper gets stuck, the brake pads are permanently pressed against the rotor causing:

  • Vibration in brake pedal
  • Vibration on steering wheel
  • Illumination of the ABS or brake warning light
  • Grinding noise from one corner of the vehicle
  • Vehicle pulls to one side of the road
  • Braking requires more pressure on the brake pedal
  • The repair for a seized brake caliper, the brake pads, brake rotor, and brake caliper must be replaced or vibration will remain after the new caliper is installed. Changing the brake fluid and flushing the brake system according to manufacturer specified intervals can help improve longevity of the brake caliper.

    The exhaust recirculation valve (EGR) on the 1990-2007 Honda Accord 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 radio and climate control display can go dark on some models. It will be necessary to replace the affected unit to correct this concern. Some customers have reported receiving help from Honda regarding this repair.

    If the brake pedal feels hard the first time it is pressed in the morning, it could be due to a problem with the vacuum supply hose for the brake booster. A revised brake booster hose is available to address this concern.

    The ABS modulator (hydraulic unit) can leak air into the brake system and cause a low brake pedal. A new ABS modulator will be needed if it is diagnosed to be the source of the leak.

    The computer can misinterpret a low battery voltage and can cause a false Check Engine (MIL) light to come on. Updating the PCM can correct this issue.
