2003 Acura RL Problems

Sensor Problems May Cause SRS Light To Turn On

The Airbag (SRS) warning light may illuminate due to one or more failed sensors. Our technicians recommend complete diagnoses of any stored fault codes because these sensors can be very expensive to replace.

Check Engine Light for Running Rough and Difficulty Starting

The exhaust recirculation valve (EGR) on the 1996-2012 Acura RL 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.

    Engine Stalls While Driving and Will not Start

    The 1996-2006 Acura RL may have issues with the fuel pump and fuel injection relays.

    These relays send power to the fuel pump and fuel injectors when the key is turned to the “ON” position. So, when they fail, there is no electrical current to the necessary fuel system components to send fuel into the engine, causing engine stalling or failure to start.

    In this situation, there are many other possibilities, so testing components is vital for time and money savings.

    If the relays test bad, they must be replaced with relays specific for that circuit.

    To help prolong the life of your under-hood electrical components, ensure the lid for the fuse block is closed, and any factory sealing material is correctly installed.

    Bought a 9.5+ condition '03 RL w 47,000 miles on it last fall. Looks just like the one in the picture above. These cars are made in Japan and bulletproof. Plenty of room in the cabin and the trunk, very comfortable and easy to drive. Great ergonomics! The CD stereo in my '03 totally rocks, AC is freezing. Not hot rods, per se, but totally reliable luxo-cruisers. If you can find a clean one wi...
