REMOVAL
WA RN ING:
To avoid the danger of being scalded, never drain the coolant when the engine is hot.
1. Remove mass air flow sensor harness connector from mass air flow sensor and clamp.
2. Release fuel pressure.
Refer toEC-34, "
FUEL PRESSURE RELEASE"(WITH EURO-OBD),EC-399, "FUEL PRESSURE
RELEASE"(WITHOUT EURO-OBD).
3. Remove air cleaner case and air duct assembly.
Refer toEM-15, "
Removal and Installation".
4. Drain coolant when engine is cooled. Refer toCO-9, "
DRAINING ENGINE COOLANT".

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)
lA new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.
lThe slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.
lThe slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the illustra-
tion below.
CAUTION:
lDo not pull the harness or wires when disconnecting the connector.
lBe careful not to damage the connector support bracket when disconnecting the connector.
