2003 Acura CL Problems

Check Engine and D4 Lights Flashing

The Acura 3.2CL 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 1998-2003 Acura CL 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.

    2003 Acura CL Recalls

    Driver's Front Air Bag Defective

    In a crash that deploys the driver's front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front driver's air bag inflator free of charge to correct the concern.

    Front Airbag Inflator Module

    This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Honda dealers will replace the affected airbag inflator modules to correct this concern.

    Replacement Airbag Inflator Could Be Defective

    Honda is recalling 2,430 vehicles because a driver's airbag inflator, installed as a replacement part, may be defective. In the event of deployment, these inflators could produce excess internal pressure and rupture, increasing the risk of injury to vehicle occupants. Dealers will inspect and replace the driver's airbag inflator as necessary. The recall is expected to begin by June 27, 2011.
