Line Pressure Test
LINE PRESSURE TEST PORTS
+Location of line pressure test ports.
+Always replace line pressure plugs as they are self-seal-
ing bolts.
LINE PRESSURE TEST PROCEDURE
1. Check A/T and engine fluid levels. If necessary, add fluid.
2. Drive vehicle for approx. 10 minutes or until engine oil and
ATF reach operating temperature.
ATF operating temperature:
50 - 80ÉC (122 - 176ÉF)
3. Install pressure gauge to corresponding line pressure port.

TROUBLE DIAGNOSIS Ð Basic Inspection
AT-1044

DIAGNOSTIC PROCEDURE
CHECK INPUT SIGNAL.
1. Start engine.
2. Select ªTCM INPUT SIGNALSº
in Data Monitor.
3. Read out the value of ªVHCL/S
SEzMTRº while driving.
Check the value changes
according to driving speed.
------------------------------------------------------------------------------------------------------------------------------------OR------------------------------------------------------------------------------------------------------------------------------------
1. Start engine.
2. Check voltage between TCM
terminal
V40and ground while
driving at 2 to 3 km/h (1 to 2
MPH) for1m(3ft)ormore.
Voltage:
Voltage varies between
less than 1V and more than
4.5V.
OK
cNG
Check the following items:
+Vehicle speed sensor
and ground circuit for
vehicle speed sensor
Refer to EL section
(ªMETERS AND
GAUGESº).
+Harness for short or
open between TCM and
vehicle speed sensor
(Main harness)
Perform ªSELF-DIAGNOSIS CODE CON-
FIRMATION PROCEDUREº, AT-1066.
OK
cNG
1. Perform TCM input/
output signal inspection.
2. If NG, recheck TCM pin
terminals for damage or
loose connection with
harness connector.

Inspection for spill tube airtightness
Before the rocker cover is installed, perform the inspection as
follows.
1. Connect the handy vacuum pump to the spill hose.
2. Check that the airtightness is maintained after the negative
pressure shown below is applied.
Standard:
þ53.3 to þ66.7 kPa (þ533 to þ667 mbar, þ400 to
þ500 mmHg, þ15.75 to þ19.69 inHg)
Air bleeding of fuel piping
After the repair, bleed air in the piping by pumping the priming
pump up and down until it becomes heavy.
Injection pressure test
1. Install injection nozzle assembly to injection nozzle tester
and bleed air from flare nut.
2. Pump the tester handle slowly (one time per second) and
watch the pressure gauge.
3. Read the pressure gauge when the injection pressure just
starts dropping.
Initial injection pressure:
Used
19,026 kPa (190.3 bar, 194 kg/cm
2, 2,759 psi)
New
19,516 - 20,497 kPa (195.2 - 205.0 bar, 199 - 209
kg/cm
2, 2,830 - 2,972 psi)
Limit
16,182 kPa (161.8 bar, 165 kg/cm
2, 2,346 psi)
+The injection nozzle assembly has a 2-stage pressure injec-
tion function. However, the judgement should be made at the
first stage of the valve opening pressure.

REMOVAL
1. Remove the following:
+Engine coolant draining
+Charge air cooler
+Air inlet pipe
+Throttle body
+Rocker cover
+Oil level gauge guide
+EGR guide tube
+EGR volume control solenoid valve
+Fuel hose
+Injection tube
+Radiator upper hose
+Radiator shroud
+Cooling fan
+Drive belt
+Vacuum pipe
+Vacuum pump
2. Move the power steering pump.
3. Remove the harness connector from the fuel injection pump.
+After pulling the connector stopper all the way back, remove
the connector.
+When the stopper is pulled all the way back, the interlocked-
connector will come off.
As for installation, when the connector is pushed all the way
forward until the stopper locks, the interlocked-connector is
inserted.
4. Remove the fuel injection pump rear bracket.
5. Remove the chain cover.
+Remove the installation bolts A, B, and C shown in the fig-
ure (left).
CAUTION:
During chain cover removal, seal the opening to prevent
foreign objects from getting into the engine.
6. Fix the internal mechanism of the idler gear (scissors gear
structure).
a. Remove the plug on the front side of the gear case.
b. While turning the crankshaft pulley clockwise, check the
tightening bolt hole of the idler gear internal mechanism
through the plug hole.
+Conduct the visual check using a mirror.
+When checking, note that there are 2 other holes (with no
thread) beside the tightening bolt hole on the idler gear.
