IDLE MIXTURE INSPECTION

1) Perform inspection with the vehicles in the following
condition:

Engine coolant temperature: 8095*C
Lights and all accessories: OFF

Transmission:Neutral (P range for vehicles with
automatic transmission)

(2)Turn the ignition switch to OFF and connect the MUT-II to
the diagnosis connector:

3)Check that the basic ignition timing is within the standard
value.

Standard value: 5' BTDC + 39

Run the engine at 2,500 rlmin for 2 minutes.
Set the CO, HC tester;

Check the CO contents and the HC contents at idle.

Standard value

CO contents: 0.5% or less

HC contents: 100 ppm or less

If there is a deviation from the standard value, check the
following items:

Diagnosis output

Closed-loop control (When the closed-loop
control is normal, the output signal of the oxygen
sensor changes between400 mV and 600
1,000 mV at idle:)

Fuel pressure
Injector

Ignition coil, spark plug cable, spark plug
Leak in the EGR system and in the EGR valve
Evaporative emission control system
Compression pressure

NOTE

Replace the three way catalyst when the CO and HC
contents are not within the standard value, even though
the result of the inspection is normal on all items
