(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure


1,300 kPa (13.3 kgf
cm
2, 189 psi)
Minimum pressure: 1,000 kPa (10.2 kgf
cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf
cm
2, 14 psi)
NOTICE:

Always use a fully charged battery to obtain engine
speed of 250 rpm or more.

Check other cylinder's compression pressure in the
same way.

This measurement must be done in as short a time as
possible.
(4) If the cylinder compression in one or more cylinders
is low, pour a small amount of engine oil into the cyl-
inder through the spark plug hole and repeat steps
(1) through (3) for the cylinders that have low com-
pression.
HINT:

If adding oil helps increase the compression, the piston
rings and/or cylinder bore may be worn or damaged.

If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check CO/HC concentration at idle.
Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given
below.

Check heated oxygen sensor operation.

See the table below for possible causes, and then inspect and repair the applicable causes if
necessary.

1. INSPECT INTAKE AIR SYSTEM
(a) Check for leakage or clogging between the air cleaner
housing and turbocharger inlet and between the turbo-
charger outlet and cylinder head.
(1) Clogged air cleaner...Clean or replace element
(2) Hoses collapsed or deformed...Repair or replace
(3) Leakage from connections...Check each connec-
tion and repair
(4) Cracks in components...Check and replace
2. INSPECT EXHAUST SYSTEM
(a) Check for leakage or clogging between the cylinder head
and turbocharger inlet and between the turbocharger out-
let and exhaust pipe.
(1) Deformed components...Repair or replace
(2) Foreign material in passages...Remove
(3) Leakage from components...Repair or replace
(4) Cracks in components...Check and replace
3. CHECK TURBOCHARGING PRESSURE
(a) Warm up the engine.
(b) Using a 3±way connector, connect SST (turbocharger
pressure gauge) to the hose leading to the intake air con-
nector.
SST 09992 ± 00242
(c) While depressing the clutch pedal, press the accelerator
pedal down to the full. Measure the turbocharging pres-
sure at maximum speed (5,100 to 5,250 rpm).
Standard pressure:
15 to 45 kPa (0.15 to 0.46 kgf/cm
2, 2.2 to 6.5 psi)
If the pressure is less than specification, check both the intake
air and exhaust systems for leakage.
If there is no leakage, check if the actuator hose has discon-
nected. If not, check the turbocharger.
If the pressure is greater than specification, check if the actua-
tor hose has disconnected or cracked. If not, check the turbo-
charger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect power source voltage
(1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wiring
harness side.
Voltage: 4.5 to 5.5 V
(4) Turn the ignition switch OFF.
(5) Reconnect the turbo pressure sensor connector.

(1) Turn the ignition switch ON.
(2) Disconnect the vacuum hose from the turbo pres-
sure sensor.
(3) Connect a voltmeter to terminals 35 (PIM) and 28
(E2) of the ECM and measure the output voltage
under atmospheric pressure.
(4) Apply vacuum to the turbo pressure sensor in 13.3
kPa (100 mmHg, 3.94 in.Hg) segments to 66.7 kPa
(500 mmHg, 19.96 in.Hg).

ON±VEHICLE INSPECTION
HINT:
In a malfunction where the EGR system is always on, black smoke or white smoke may be emitted from the
exhaust pipe. If this occurs, inspect the EGR system as well.
1. INSPECT SEATING OF EGR VALVE
(a) Start the engine and check that it starts and runs at idle.
2. INSPECT HOT ENGINE CONDITION (WHEN USING HAND±HELD TESTER)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and run it at idle.
(c) Select the ACTIVE TEST mode on the hand±held tester.
HINT:
Refer to the hand±held tester operator's manual for further details.
(d) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(e) Check that the AFM reading is 5
ega
8 g/s with the engine idling.
(f) Operate the EGR valve with a hand±held tester. Regulate the valve opening angle to 0, and check that
the AFM reading is 11
ega
17 g/s..
If the AFM reading is out of range in either (e) or (f), replace the EGR valve.
If the AFM is out of range in both (e) and (f), replace the air flow meter (air cleaner) and check the EGR valve
operation again.
3. INSPECT HOT ENGINE CONDITION (WHEN NOT USING HAND±HELD TESTER)
(a) Install the vacuum gauge.
(1) Using a 3±way connector, connect a vacuum gauge to the hose between the intake manifold and
the turbo pressure sensor.
(b) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(c) Check that the vacuum gauge indicates about more than 2.5 kPa (19 mmHg 0.7 in Hg).
(d) Stop the engine (IG OFF), remove the EGR valve connector, restart the engine, and check that load
under idling is less than 2.5 kPa (19 mmHg 0.7 in Hg).
If the load pressure exceeds the above value, replace the EGR valve.
