PRECAUTIONS
 If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.
 After installing plate clamps, apply force to them in the direction of
the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000003852785
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
 Avoid prolonged and repeated contact with oils, particularly used engine oils.
 Wear protective clothing, including impervious gloves where practicable.
 Do not put oily rags in pockets.
 Avoid contaminating clothes, particularly underpants, with oil.
 Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
 First aid treatment should be obtained immediately for open cuts and wounds.
 Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
 Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
 Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
 If skin disorders develop, obtain medical advice without delay.
 Where practical, degrease components prior to handling.
 Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
Air ConditioningINFOID:0000000003852786
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
HA section “REFRIGERATION SYSTEM” for specific instructions.

COMPONENT DESCRIPTION
Gas Sensor
The gas sensor (1) is attached on the bumper upper retainer. It
detects smell of exhaust gas and converts it into a duty ratio which is
then input into the A/C auto amp.
Gas Sensor Circuit
SMELL OF EXHAUST GAS INPUT PROCESS
Gas sensor detects ambient atmospheric CO and NO2, and converts them to values of resistance. The values
are converted to signals with the gas sensor internal circuit, then auto amp. inputs the signals.
Gas sensor has a construction that detects CO and NO
2 by gas sensor element from the air intake of the case
through a filter (waterproof sheet). It sends output signals to auto amp. in response to a resistance value con-
version by gas sensor elements. Output signals prevent a smell of exhaust gas from getting into vehicle by
performing corrections according to various driving conditions.

InspectionINFOID:0000000003793121
ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check the engine oil level is within the
range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
 Oil pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Water pump cover
 Oil cooler
 Valve timing control covers (bank 1 and bank 2)
 Mating surface between cylinder head and rocker cover
 Mating surface between front timing chain case and rear timing chain case
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
 Mating surface between rear timing chain case and oil pan (upper)
 Mating surface between cylinder block and cylinder head
 Crankshaft oil seals (front and rear)
 Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burn yourself, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
Inspection".
2. Remove splash guard (RH). Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".
