2. Disconnect harness connector at
oil pressure sensor. Remove
oil pressure sensor using suitable tool and install suitable tools
(A/B).
CAUTION:
Do not drop or shock oil pressure sensor.
3. Start engine and warm it up to normal operating temperature.
4. Check engine oil pressure with engine running under no-load. NOTE:
• When engine oil temperature is low, engine oil pressure becomes high.
• If difference is extreme, check oil passage and oil pump for engine oil leaks.
5. After the inspections, install oil pressure sensor as follows:
a. Remove old liquid gasket adhering to oil pressure sensor and engine.
b. Apply liquid gasket and tighten oil pressure sensor to specification. Use Genuine Liquid Gasket or equivalent. Refer to GI-22, "
Recommended Chemical Products and
Sealants".
6. Check engine oil level.
7. After warming up engine, check that ther e is no engine oil leaks with the running engine.

WARNING:
• Be careful not to get burned, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause ski n cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, park the vehicle on a level surface and check for engine oil leaks. Refer to LU-7,
"Inspection".
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.
RefillingINFOID:0000000012432202
1. Install drain plug with new copper sealing washer. Refer to EM-34, "Exploded View".
CAUTION:
• Be sure to clean drain plug.
• Do not reuse copper sealing washer.
2. Refill with new engine oil.
CAUTION:
• The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
• Always use oil level gauge to determine the pr oper amount of engine oil in the engine.

PRECAUTIONS
General Precautions
INFOID:0000000012433162
• Do not operate the engine for an extended period of time without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
• Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
• When removing a heavy component such as the engine or tran- saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
• Before starting repairs which do not require battery power: Turn off ignition switch.
Disconnect the negative battery terminal.
• If the battery terminals are disconnected, recorded memory of radio and each control unit is erased.
• To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
• Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
• Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
• Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
• Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
• After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
