2. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap
tester.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm, 17.1 psi), and check
that the pressure does not drop.
If the pressure drops, check the hoses, radiator or
water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and head.

CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±

OIL PRESSURE CHECK
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, dis±
coloring or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SG or SH, Energy Conserving II multi±
grade engine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra±
tion.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to ªFº mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL
OIL PRESSURE GAUGE
4. WARM UP ENGINE
Allow the engine to warm up to normal operating
temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle
29 kPa (0.3 kgf/cm, 4.3 psi) or more
At 3,000 rpm
245 ± 490 kPa (2.5 ± 5.0 kg f/cm, 36 ± 71 psi)
NOTICE:
wWhen inserting the oil dipstick, insert the curved tip
of the dipstick facing the same direction as the
curve of the guide.
wIf the dipstick gets caught while inserting it, do not
force it in. Reconfirm the direction of the dipstick.

6. 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.

CLEAR DIAGNOSTIC TROUBLE CODES
See page EG1±299.
SET TEST MODE
1. With the ignition switch off, using SST, connect the ter±
minals TE2 and E1 of the data link connector 1 and 2.
SST 09843±18020
2. Start the engine and check to see the malfunction indica±
tor lamp to go off.
PERFORM A SIMULATION TEST
Using the symptom simulation (See page IN ±24), apply vibra±
tion to and pull lightly on the wire harness, connector or
terminals in the circuit indicated by the malfunction code.
In this test, if the malfunction indicator lamp light up, it indi±
cates that the place where the wire harness, connector or
terminals being pulled or vibrated has faulty contact. Check
that point for loose connections, dirt on the terminals, poor fit
or other problems and repair as necessary.
HINT: After cancelling out the diagnostic trouble code in
memory and set the test mode, if the malfunction indicator
lamp does not go off after the engine is started, check thor±
oughly for faulty contact, etc., then try the check again. If the
malfunction indicator lamp still does not go off, check and
replace ECM.
CHECK FOR MOMENTARY
INTERRUPTION
As described in the preceding paragraph, abnormality detec±
tion ability in the test mode is increased compared to that in
the normal mode, so that when momentary interruptions or
momentary shorts occur in the ECM signal circuits (G, NE,
THW, THA, PIM, VTA) shown in the table below, the appro±
priate diagnostic trouble code is output.
Accordingly, when the diagnostic trouble codes shown in the
table below (13, 22, 24, 31, 41) are output during the diag±
nostic trouble code check, and inspection of the appropriate
circuits reveals no abnormality, perform the check for momen±
tary interruption as described below.
By performing the check for momentary interruption, the
place where momentary interruptions or momentary shorts are
occurring due to poor contacts can be isolated.

(1) Be sure that fuel is enough in tank.
(2) Turn ignition switch on.
(3) Using SST, connect terminals FP and + B of
data link connector 1.

Check for fuel pressure in the return hose when it
is pinched off.
Disconnect the high±tension cord from the distributor and, hold the end about 12.5 mm (1/2º)
from the ground, see if spark occurs while the engine is being cranked.
To prevent excessive fuel injected from the injectors during this test, don't crank the engine for
more than 1±2 seconds at a time.Never make a mistake with the terminal con±
nection position as this will cause a malfunc±
tion.
