Switches and Sensors
Clear the oxygen sensor lead from the clamp [A].
Remove the oxygen sensor [B].
Oxygen Sensor Installation (Equipped Models)
Never drop the oxygen sensor [A] especially on a
hard surface. Such a shock to the unit can damage
it. Do not touch the sensing part [B] and filter holes
[C] of the sensor to prevent oil contact. Oil contami-
nation from hands can reduce sensor performance.
Torque - Oxygen Sensor: 44 N·m (4.5 kgf·m, 32 ft·lb)
Run the oxygen sensor lead correctly (see Cable, Wire,
and Hose Routing section in the Appendix chapter).
Oxygen Sensor Inspection (Equipped Models)
Refer to the Oxygen Sensor Inspection in the Fuel System
Fuel Level Sensor Inspection
Fuel Pump (see Fuel Pump Removal in the Fuel System
Check that the float moves up and down smoothly without
binding. It should go down under its own weight.
If the float does not move smoothly, replace the fuel pump.
Float in Full Position [A]
Float in Empty Position [B]
Float Arm Stoppers [C]
Using the hand tester [A], measure the resistance across
the terminals in the fuel level sensor lead connector [B].
Special Tools - Hand Tester: 57001-1394
Needle Adapter set: 57001-1457
If the tester readings are not as specified, or do not
change smoothly according as the float moves up and
down, replace the fuel pump.
Fuel Level Sensor Resistance
Standard: Full position: 9.6 ∼ 12.4 Ω
Empty position: 222 ∼ 228 Ω
