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.

(d) Check the valve overall length.
Standard overall length:
Intake
103.45 mm (4.0728 in.)
Exhaust
103.60 mm (4.0787 in.)
Minimum overall length:
Intake
102.95 mm (4.0531 in.)
Exhaust
103.10 mm (4.0590 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than minimum.
12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for these:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with these width:
1.0 − 1.4 mm (0.039 − 0.055 in.)
If not, correct the valve seats as follows:
Intake:
If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.

12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats. Re-
move only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a thin coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate the valve.
(c) Check the valve face and seat for these:
If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with these width.
1.0 − 1.4 mm (0.039 − 0.055 in.)
If not, correct the valve seats as follows:
(1) If the seating is too high on the valve face, use 30°
and 45° cutters to correct the seat.
(2) If the seating is too low on the valve face, use 60°
and 45° cutters to correct the seat.
(d) Hand−lap the valve and valve seat with an abrasive com-
pound.
(e) After hand−lapping, clean the valve and valve seat.

(b) Using a hammer, tap the yoke until there is no clearance
between the bearing outer race and snap ring.
7. CHECK SPIDER BEARING
(a) Check that the spider bearing moves smoothly.
(b) Check the spider bearing axial play.
Bearing axial play: Less than 0.05 mm (0.0020 in.)
HINT:
Install new spider bearings on the flange side in the procedure
described above.
