2013 Acura TL Problems

Check Engine and D4 Lights Flashing

The 1998-2014 Acura TL V6 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.

Check Engine Light for Running Rough and Difficulty Starting

The exhaust recirculation valve (EGR) on the 1995-2014 Acura TL may fail, causing:

  • Illumination of the check 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.

    Check Engine Light and Engine Takes too Long to Start

    The 1998-2014 Acura TL 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.

    Driver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments

    The driver's frontal air bag inflator may be susceptible to moisture intrusion, which over time could cause the inflator to rupture. If this happens, it would spray metal fragments upon deployment. Dealers will replace the driver's frontal air bag inflator free of charge to resolve the concern.
