DTC P0300 Random / Multiple Cylinder Misfire
Detected
DTC P0301 Cylinder 1 Misfire Detected
DTC P0302 Cylinder 2 Misfire Detected
DTC P0303 Cylinder 3 Misfire Detected
DTC P0304 Cylinder 4 Misfire Detected
CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation for each cylinder.
The ECM counts the number of times the engine speed change rate indicates that misfire has occurred. And
when the misfire rate equals or exceeds the count indicating that the engine condition has deteriorated, the
MIL lights up.
If the misfire rate is high enough and the driving conditions will cause catalyst overheating, the MIL blinks
when misfiring occurs.

P0300Misfiring of random cylinder is detected during any particular
200 or 1,000 revolutionsIgnition system

P0301
P0302
P0303
P0304
For any particular 200 revolutions of the engine, misfiring is
detected which can cause catalyst overheating
(This causes MIL to blink)
For any particular 1,000 revolutions of the engine, misfiring is
detected which causes a deterioration in emissions
(2 trip detection logic)
HINT:
When the 2 or more codes for a misfiring cylinder are recorded repeatedly but no Random Misfire code is
recorded, it indicates that the misfires were detected and recorded at different times.

INSTALLATION
1. SET NO. 1 CYLINDER TO DTC/COMPRESSION
Turn the crankshaft clockwise, and position the slit of the intake
camshaft as shown in the illustration.
2. INSTALL DISTRIBUTOR
(a) Install a new O−ring to the housing.
(b) Apply a light coat of engine oil on the O−ring.
(c) Align the cutout of the coupling with the line of the hous-
ing.
(d) Insert the distributor, aligning the center of the flange with
that of bolt hole on the cylinder head.
(e) Tighten the hold−down bolt.

(d) Using SST, compress the compression spring.
SST 09950−40010 (09958−04010)
NOTICE:
Do not bend the universal joint of the shaft more than 20°.
(e) Using a snap ring expander, install a new snap ring to the
shaft.
4. INSTALL TILT LEVER RETAINER
NOTICE:
Make sure to install the retainer facing the correct direction
(See page SR−22).
5. INSTALL STEERING COLUMN UPPER TUBE WITH
STEERING MAIN SHAFT
(a) Install the upper tube with the shaft to the steering column
tube.
(b) Using a hexagon wrench, torque the 2 tilt steering bolts.
Torque: 20 N·m (204 kgf·cm, 15 ft·lbf)
(c) Check that the upper tube turns smoothly.
6. INSTALL COMBINATION SWITCH BRACKET
Torque the 2 bracket set bolts.
Torque: 6.0 N·m (58 kgf·cm, 53 in.·lbf)
7. INSTALL 3 TENSION SPRINGS
HINT:
Install the springs with the tilt function at maximum tilt up.
8. INSTALL STEERING COLUMN UPPER BRACKET
AND STEERING COLUMN UPPER CLAMP
(See page SR−18)
9. CHECK TILT STEERING OPERATION
