Definition:
HC adsorber (HC trap catalyst) efficiency below threshold
Description:
Engine speed is lower than 1,656 r or minlower thenm higher thenor 1,313 r or minlower thencvt higher then .Volumetric efficiency is lower than 25 percentlower thenm higher thenor 35 percentlower thencvt higher then .The accelerator pedal is not depressed.Barometric pressure is higher than 76 kPa (22.4 in. Hg).Intake air temperature is higher than -10°C (14°F).The accumulative mass airflow is higher than 2,900 g.The fuel shut-off mode continues for 3 seconds or more.After the fuel shut-off mode is terminated,the output voltage of the heated oxygen sensor (3rd) is 0.2 volt or less for 0.5 seconds.After the output voltage of the heated oxygen sensor (rear) reaches 0.5 volt,the output voltage of the heated oxygen sensor (3rd) reaches 0.5 volt within 1.5 seconds. lower then or cvt higher thenlower then or m higher thenlower then or cvt higher thenlower then or m higher then 
Cause:
