Cylinder Head InspectionS7RS0B1406027
• Remove all carbon deposits from combustion chambers.
NOTE
Do not use any sharp-edged tool to scrape
off carbon deposits. Be careful not to scuff or
nick metal surfaces when decarbonizing. The
same applies to valves and valve seats, too.

• Check cylinder head for cracks on intake and exhaust ports, combustion chambers, and head surface. Using
a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 6 locations. If distortion
limit is exceeded, correct gasketed surface with a
surface plate and abrasive paper of about #400
(Waterproof silicon carbide abrasive paper): place
abrasive paper on and over surface plate, and rub
gasketed surface against paper to grind off high spots.
Should this fail to reduce thickness gauge readings to
within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint
is often due to warped gasketed surface: such
leakage results in reduced power output.
Distortion for cylinder head surface on piston side
Limit: 0.03 mm (0.001 in.) • Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds,
using a straightedge and thickness gauge, in order to
determine whether these faces should be corrected or
cylinder head replaced.
Distortion for cylinder head surface on intake and
exhaust manifold
Limit: 0.05 mm (0.002 in.)

Voltage Check
ECM and its circuits can be checked by measuring voltage with special tool connected.
CAUTION!
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the
grommet. Therefore, do not measure circuit voltage and resistance by inserting the tester’s probe
into the sealed terminal at the harness side. Or, ECM and its circuits may be damaged by water.
• ECM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ECM with couplers disconnected from ECM.

1) Remove ECM (1) from its bracket by referring to “Electric Throttle Body System Calibration in Section 1C”.
2) Connect special tool (2) between ECM and ECM connectors securely.
3) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that the battery voltage is 11 V or
more when ignition sw itch is ON position.
