HC contents: 100 ppm or less  
7. If the CO and HC contents do not remain inside the standard value, check the 
following items:  
Diagnostic output  Closed-loop control (When the closed-loop control is carried out normally, the 
output signal of the heated oxygen sensor changes between 0 - 400 mV and 
600 - 1,000 mV at idle.)  Fuel pressures  Injector  Ignition coil, spark plug  EGR system and EGR valve leak  Evaporative emission system  Compression pressure

NOTE: Replace the catalytic converter when the CO and HC 
contents do not remain inside the standard value, even 
though the result of the inspection is normal for all items.
