WIRE COLOR AND TERMINAL NUMBER
In some parts of the instrumental panel wiring harness, the
same wire color (i.e. SB: Sky Blue) is used for all the wiring
to a specific connector.
In order to identify the wiring, the terminal number is printed
on the wiring.
Install the wiring to the connector position with the same
terminal number.
Some early production Vehicles may not have these terminal
numbers printed.

DTC P0325Knock Sensor 1 Circuit Malfunction
CIRCUIT DESCRIPTION
Knock sensor is fitted to the cylinder block to detect engine knocking. This sensor contains a piezoelectric element which
generates a voltage when it becomes deformed, which occurs when the cylinder block vibrates due to knocking. If engine
knocking occurs, ignition timing is retarded to suppress it.
DTC No. DTC Detecting Condition Trouble Area
P0325No knock sensor 1 signal to ECM with engine speed,
1,200 rpm or more.
Open or short in knock sensor1 circuit

Knock sensor 1 (looseness)

ECM
If the ECM detects the above diagnosis conditions, it operates the fall safe function in which the corrective retard angle
value is set to the maximum value.

Diagnostic Trouble Code No. and Detection Item

Circuit Description
The major role and operation, etc. of the circuit
and its component parts are explained.

Indicates the diagnostic trouble code, diagnostic
trouble code set parameter and suspect area of
the problem.

GENERAL MAINTENANCE
1. GENERAL NOTICE

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance services after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item can cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the LEVEL lines on the see-through reservoir at normal tem-
perature (20°C (68°F)).
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(See page CO-14)
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL

Check the indicator.

When the indicator color is blue, the condition is satisfactory. A red color indicates that distilled water
must be added, and white indicates that charging is necessary.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see-through reservoir.
(See page BR-4)
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL

Check the level on the dipstick.

The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
Visually check the overflow plug and oil pan for fluid leaks or traces of fluid.

8. INSTALL SNAP RING
(a) Install 2 new snap rings of equal thickness which will allow
0 mm (0 in.) axial play.
HINT:
Do not reuse the snap rings.
(b) Using a hammer, tap the yoke until there is no clearance
between the bearing outer race and snap ring.
9. INSTALL FLANGE YOKE TO SLEEVE YOKE (OR PRO-
PELLER SHAFT)
(a) Align the matchmarks on the propeller shaft and flange
yoke or flange yoke and sleeve yoke.
(b) Install the flange yoke to the sleeve yoke (or propeller
shaft).
HINT:
Install 2 new spider bearings and snap ring on the flange yoke
side in the procedure described above.
