CAMSHAFT INSTALLATION
(1) Apply engine oil to journals and cams of the
(2) Install the camshafts on the cylinder head. Use care not to confuse the intake camshaft with th e
exhaust one. The intake camshaft has a slit on its rear
end for driving the crankshaft position sensor.
(3) Install the crankshaft sprocket

to an end of the crankshaft, and turn the until
the timing marks are lined up, setting No. cylinder to
the TDC.

ENGINE On-vehicle Service
IDLE MIXTURE CHECK
11100210081
1.Before inspection, set vehicles in the following co ndition:
lEngine coolant temperature:
l Lights, electric cooling fan and all accessories: O FF
lTransaxle: Neutral (P range on vehicles with
2.After turning the ignition switch to OFF, connect t he scan
tool to the data link connector.
3.Start the engine and run it at 2,500 for 2 minutes.
4. Set the CO, HC tester.
5. Check the CO contents and the HC contents at idl e.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
6. If the idle speed is outside the standard value, check
the following items: l Diagnostic output
l Closed-loop control (When the closed-loop control
is carried out normally, the output signal of the h eated
oxygen sensor repeats between and
,000 at idle.)
l Fuel pressure
I n j e c t o r
lIgnition coil, spark plug cable, spark plug
lEGR system and the EGR valve leak
l Evaporative emission control system
Compression pressure
NOTE
Replace the three-way catalyst whenever the CO and
HC contents do not remain inside the standard value .
(even though the result of the inspection is normal on
all items.)
COMPRESSION PRESSURE CHECK
1.Before inspection, check that the engine oil, start er and
battery are normal. Also, set the vehicle to the fo llowing
condition:
lEngine coolant temperature:
lLights, electric cooling fan and all accessories: O FF
lTransaxle: Neutral (P range on vehicle with
2. Disconnect the spark plug cables.
3. Remove all spark plugs.
4.Disconnect the relay (ASD relay) connector to prevent
a spark.
