CHECKING COMPRESSION PRESSURE
1. Warm up the engine to full operating temperature.
2. Release the fuel pressure. Refer to EC-182, "Work Procedure"
.
3. Remove the ignition coil and spark plug from each cylinder. Refer to EM-40, "Removal and Installation"
.
4. Connect engine tachometer (not required in use of CONSULT).
5. Disconnect the fuel injector harness connector to avoid any residual fuel injection during the measure- ment.
6. Install the compression tester with the adapter into the spark plug hole.
• Use compression tester whose end (a) (rubber portion) is smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be caught by
cylinder head during removal.
7. With the accelerator pedal fully depressed, turn the ignition switch to the “START” position to crank over
the engine. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform
these steps to check each cylinder.
Unit: kPa (kg/cm2, psi) / rpm
CAUTION:
Always use a fully charged battery to ob tain specified engine cranking speed.
• If the engine speed is out of specified rpm range, check the battery. Check engine speed again with a fully
charged battery.
• If compression pressure is below minimum value, check valve clearances and parts associated with com- bustion chamber (valve, valve seat, piston, piston ri ng, cylinder bore, cylinder head, cylinder head gasket).
After the checking, measure compression pressure again.
• If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression.
• If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the pis- ton rings and replace if necessary.
• If the compression pressure remains at low level des pite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.

Camshaft Runout
1. Put the camshaft on a V-block supporting the No.2 and No.5 journals.
CAUTION:
Do not support the No. 1 journal (on the side of the cam-
shaft sprocket) because it has different diameter from the

WARNING:
Check when engine is cold so as to preven t burns from any splashing engine oil.
CAUTION:
Perform this inspection only when DTC P0011, P0014, P052A, P052B is detected in self-diagnostic
results of CONSULT and it is directed according to inspection procedure of EC section. Refer to EC-
210, "Diagnosis Procedure".
1. Check engine oil level and adjust oil level as necessary. Refer to LU-9, "Inspection"
.
2. Remove the intake valve timing intermediate lock control solenoid valve, intake valve timing control sole- noid valve, and exhaust valve timing control solenoid valve. Refer to EM-58, "Intake Valve Timing Interme-
diate Lock Control Solenoid Valve, Intake Valve Timing Control Solenoid Valve, and Exhaust Valve Timing
Control Solenoid Valve".
3. Perform the following procedure to prevent the engi ne from being unintentionally started while checking.
a. Release fuel pressure. Refer to EC-182, "Work Procedure"
.
b. Disconnect injector harness connectors.
4. Crank engine, and then make sure that engine oil comes out of the valve timing control cover oil holes (A). End cranking after
checking.
WARNING:
Be careful not to touch rotating parts (drive belt, crankshaft
pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing intermedi-
ate lock control solenoid valve, intake valve timing control
solenoid valve, exhaust valve timing control solenoid
valve installation holes during cranking. Use a shop cloth
to prevent engine oil from splashing on worker, engine
components and vehicle.
• Do not allow engine oil to get on rubber componen ts such as drive belts or engine mount insula-
tors. Immediately wipe off any splashed engine oil.
5. If engine oil does not come out from valve timing cont rol cover oil holes (A), diagnose problem in lubrica-
tion circuit such as dirty oil groove between oil strainer and intake valve timing intermediate lock control
solenoid valve, intake valve timing control solenoid valve, or exhaust valve timing control solenoid valve.
Refer to LU-7, "Lubrication Circuit"
.
a. Remove components between intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, exhaust valve timing c ontrol solenoid valve and camshaft sprocket (INT) or
camshaft sprocket (EXH), (if necessary) and then check each oil groove for clogging.
b. Clean oil groove if necessary. Refer to LU-7, "Lubrication Circuit"
.
6. After inspection, install the remaining components in the reverse order of removal.
