IDLE AIR CONTROL (IAC) VALVE
ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE OPERATION
(a) Initial conditions:
Engine at normal operating temperature
Idle speed check correctly
Transmission in neutral position
A/C switch OFF
(b) Using SST, connect terminals TE1 and E1 of the
DLC1.
SST 09843−18020
(c) After engine speed is kept at approx. 1,000 rpm for 5 se-
conds, check that it returns to idle speed.
If the engine speed operation is not as specified, check the IAC
valve, wiring and ECM.
(d) Remove the SST from the DLC1.
SST 09843−18020
2. INSPECT IAC VALVE RESISTANCE
NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10°C
(14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to
100°C (212°F).
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal +B and other terminals (RSC, RSO).
Resistance:
Cold: 17.0 − 24.5 Ω
Hot: 21.5 − 28.5 Ω
If resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.
3. INSPECT AIR ASSIST SYSTEM
(a) Initial conditions:
Engine at normal operating temperature
Idle speed check correctly
Transmission in neutral position
A/C switch OFF

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SH Energy−Conserving II or SJ,
Energy−Conserving or ILSAC multigrade engine oil.
SAE 5W−30 is the bset choise for your vehicle, for
good fuel economy, and good starting in cold
weather.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the dip-
stick.
If low, check for leakage and add oil up to ”F” mark.
NOTICE:
Do not fill with engine oil above the ”F” mark.
When inserting the dipstick, insert the curved tip of
the dipstick facing the same direction as the curve of
the guide.
If the dipstick gets caught while inserting it, do not
force it in. Reconfirm the direction of the dipstick.

7. REMOVE OIL PRESSURE GAUGE AND REINSTALL
OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833−00080, THREE BOND 1344,
LOCTITE 242 or equivalent
(c) Reinstall the oil pressure switch.

INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON®II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir cap dipstick. If the fluid is cold, check that it is within
the COLD LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80°C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem.
(f) With the engine idling, measure the fluid level in the oil
reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system.
(i) Check the fluid level.
