Using a non±residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the water inlet housing as shown in
the illustration.
Seal packing: Part No. 08826±00100 or equivalent

Install a nozzle that has been cut to a 3 ± 5 mm (0.12
± 0.20 in.) opening.
HINT:
Avoid applying an excessive amount to the surface.

Parts must be assembled within 3 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.

Immediately remove nozzle from the tube and rein-
stall cap.
(c) Install the water inlet housing with the 8 bolts and 2 nuts.
Uniformly tighten the bolts and nuts, in several passes, in
the sequence shown.
Torque: 8 N´m (80 kgf´cm, 69 in.´lbf)
(d) Install the engine wire band.
(e) Install the engine wire clamp.
27. INSTALL KNOCK SENSORS
(a) Using SST, install the 2 knock sensors.

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.

E6 Connector
(a) Remove the glove compartment (See page SF±68).
(b) Disconnect the E6 connector of ECM.
INSPECTION PROCEDURE
Replace knock sensor. 1 Check continuity between terminal KNK of ECM connector and body ground.
OK:
Check knock sensor (See page SF±61).Measure resistance between terminal KNK of ECM connector
and body ground.
Resistance: 1 MW or higher
Connector being checked is connected.
Indicates the condition of the connector of ECU during the check.
PREPARATION:

Inspection Procedure
Use the inspection procedure to determine if
the circuit is normal or abnormal, and, if it is
abnormal, use it to determine whether the
problem is located in the sensors, actuators,
wire harness or ECU. IN±30
