Targeted Timing Varying Operation
Diagnostic Information and Procedures
Compression CheckS6RW0D1404001
Check compression pressure on all 4 cylinders as
follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
NOTE
After warming up engine, place transmission
gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T model), and set
parking brake and block drive wheels.
3) Remove air cleaner assembly with air suction hose
referring to “Air Cleaner Assembly Removal and
Installation”.
4) Remove cylinder head upper cover.
5) Remove ignition coil assemblies and all spark plugs
referring to “Spark Plug Removal and Installation in

2) Lift down the valve by turning crankshaft to 360°.
3) Hold tappet at that position using special tool as
follows.
a) Remove its housing bolts.

(A): 09916–670214) Turn camshaft by approximately 90° clockwise and
remove shim (3).
WARNING!
Never put in the hand between camshaft and
tappet.
5) Using a micrometer (2), measure the thickness of
the removed shim (1), and determine replacement
shim by calculating the thickness of new shim with
the following formula and table.
Shim thickness specification
Intake side:
A = B + C – 0.20 mm (0.008 in.)
Exhaust side:
A = B + C – 0.30 mm (0.012 in.)
A: Thickness of new shim
B: Thickness of removed shim
C: Measured valve clearance
For example of intake side:
When thickness of removed shim is 2.40 mm (0.094
in.), and measured valve clearance is 0.45 mm
(0.018 in.).
A = 2.40 mm (0.094 in.) + 0.45 mm (0.018 in.) – 0.20
mm (0.008 in.) = 2.65 mm (0.104 in.)
