5 CHECK SPARK PLUG AND SPARK OF MISFIRING CYLINDER
(a) Remove the ignition coil assembly.
(b) Remove the spark plug.
(c) Check the spark plug type.
Recommended spark plug:
SupplierType
DENSOK16R–U11
(d) Check the spark plug electrode gap.
Standard: 1.0 to 1.1 mm (0.039 to 0.043 in.)
Maximum: 1.3 mm (0.047 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the
ground electrode. Do not touch the tip. Never attempt to ad-
just the gap of a used plug.
(e) Check the electrode for carbon deposits.
(f) Perform a spark test.
CAUTION:
Completely disconnect each injector connector.
NOTICE:
Do not crank the engine for more than 5 to 10 seconds.
(1) Install the spark plug to the ignition coil, and connect
the ignition coil connector.
(2) Disconnect the injector connector.
(3) Ground the spark plug.
(4) Check if a spark occurs while the engine is being
cranked.
OK: A spark jumps across electrode gap.
(g) Reinstall the spark plug.
(h) Reinstall the ignition coil assembly.
OK Go to step 8

(b) For engine type 3ZZ–FE.
(1) Using a micrometer, measure the diameter of the
piston. Align the micrometer so it is 13.5 mm (0.531
in.) from the bottom of the piston and at right angles
(90) to the piston pin holes as illustrated.
Piston diameter:
78.960 to 78.975 mm (3.1087 to 3.1091 in.)
If the diameter is not as specified, replace the piston.
16. INSPECT PISTON OIL CLEARANCE
(a) Subtract the piston diameter measurement from the cylinder bore diameter measurement.
Standard oil clearance: 0.073 to 0.096 mm (0.0029 to 0.0038 in.)
Maximum oil clearance: 0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace all of the piston assembly.
If necessary, replace the cylinder block.
17. INSPECT PISTON PIN OIL CLEARANCE
(a) Using a caliper gauge, measure the piston pin bore diam-
eter.
Piston pin bore diameter:
20.006 to 20.015 mm (0.7876 to 0.7880 in.)
Markmm (in.)
A20.006 to 20.009 (0.7876 to 0.7878)

C20.013 to 20.015 (0.7879 to 0.7880)
If the diameter is not as specified, replace the piston assembly.
(b) Using a micrometer, measure the piston pin outer diame-
ter.
Piston pin outer diameter:
20.004 to 20.013 mm (0.7876 to 0.7879 in.)
Markmm (in.)
A20.004 to 20.007 (0.7876 to 0.7877)
B20.008 to 20.010 (0.7877 to 0.7878)
C20.011 to 20.013 (0.7878 to 0.7879)
If the diameter is not as specified, replace the piston assembly.
