GENERAL
OUTLINE OF CHANGES
Some service procedures have been revised as the following changes have been made to comply to
the Emission Regulation StepIII.
DInjection timing and idle speed check and adjustment have bee changed as the electronic-controlled
fuel injection pump has been introduced.
DThe oil pan has a cover in order to reduce noise due to an enhanced engine output.
DA crank angle sensor and crankshaft sensing blade have been added due to the introduction of
an electronic-controlled fuel injection pump. Due to this change, the timing belt front lower cover
has been reshaped.
DThe tightening torque of the cylinder head bolts and the cylinder head gasket have been changed.

Reference
When the cylinder (defective
cylinder) whereidling conditiondoes
not change is detected after
suspending the injector, go to (1)
and inspect the spark plug, the
ignition coil, the connector, and the
harness of the defective cylinder.
(When more than one cylinder are
detected, inspect all of them.)
When all the cylinders are OK, go to
(2).(1)Check the following connectors:
B-107 and the ignition coil
connectors, which correspond to
defective cylinders (B-101, B-108,
B-112, B-113, B-116, B-119).NG
