HINT:

Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction (See FREEZE FRAME DATA ).

  1. INSPECT INTAKE MANIFOLD (SCV OPERATION) 
    1. Inspect the swirl control valve (See ON-VEHICLE INSPECTION ).

    NG : REPLACE INTAKE MANIFOLD
