5) Remove the clip holding the harness.
6) Apply spray-type lubricant to the threaded por-
tion of rear oxygen sensor, and leave it for one
minute or more.
7) Remove the rear oxygen sensor.
CAUTION:

B: INSTALLATION
1) Before installing rear oxygen sensor, apply the
anti-seize compound only to the threaded portion of
rear oxygen sensor to make the next removal eas-
ier.
Anti-seize compound:
NEVER-SEEZ NS-165 or the equivalent
CAUTION:
Never apply anti-seize compound to the protec-
tor of rear oxygen sensor.
2) Install the rear oxygen sensor.

Fuel Delivery, Return and Evaporation Lines
FUEL INJECTION (FUEL SYSTEMS)
CAUTION:
•Pull the connector to ensure it is connected
securely.
•Make sure the two retainer pawls are en-
gaged in their mating positions in the connec-
tor.
•Be sure to inspect the hoses and their con-
nections for fuel leakage.
2) Connect the fuel delivery hose to the pipe with
an overlap of 20 to 25 mm (0.79 to 0.98 in).
Type A: When the amount of inserting is specified.
Type B: When the amount to be inserted is not
specified.
2: 2.5±1.5 mm (0.098±0.059 in)
L: 22.5±2.5 mm (0.886±0.098 in)
3) Connect the evaporation hose to the pipe with
an overlap of 15 to 20 mm (0.59 to 0.79 in).
L: 17.5±2.5 mm (0.689±0.098 in)
CAUTION:
Be sure to inspect the hoses and their connec-
tions for fuel leakage.
C: INSPECTION
1) Make sure that there are no cracks on the fuel
pipes and fuel hoses.
2) Make sure the fuel pipe and fuel hose connec-
tions are tightened firmly.

2. Compression
A: INSPECTION
CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself during measure-
ment.
1) After warming-up the engine, turn the ignition
switch to OFF.
2) Make sure that the battery is fully charged.
3) Release the fuel pressure.
PRESSURE, PROCEDURE, Fuel.>
4) Remove all the spark plugs. 4, REMOVAL, Spark Plug.>
5) Check the starter motor for satisfactory perfor-
mance and operation.
6) Hold the compression gauge tightly against the
spark plug hole.
NOTE:
When using a screw-in type compression gauge,
the screw (put into cylinder head spark plug hole)
should be less than 18 mm (0.71 in) long.
7) Fully open the throttle valve.
8) Crank the engine by means of the starter motor,
and read the maximum value on the gauge when
the pointer is steady.
9) Perform at least two measurements per cylinder,
and make sure that the values are correct.
Compression (350 rpm and fully open throttle):
Standard:
1,275 — 1,471 kPa (13.0 — 1.50 kgf/cm2,
185 — 213 psi)
Service limit:
1,128 kPa (11.5 kgf/cm2, 164 psi)

Basic Diagnostic Procedure
WIRING SYSTEM
•Each connector number shown in the wiring dia-
gram corresponds to that in the wiring harness. The
location of each connector in the actual vehicle is
determined by reading the first character of the
connector (for example, a “F” for F8, “i” for i16, etc. )
and the type of wiring harness. The first character
of each connector number corresponds to the area
or system of the vehicle.
