DTC P0303 Cylinder 3 Misfire Detected
DTC P0304 Cylinder 4 Misfire Detected
CIRCUIT DESCRIPTION
ECM monitors crankshaft revolution speed and engine speed via the crankshaft position sensor and cylinder No.
via the camshaft position sensor. Then it calculates the change in the crankshaft revolution speed and from how
many times such change occurred in every 200 or 1000 engine revolutions, it detects occurrence of misfire.
When ECM detects a misfire (misfire rate per 200 revolutions) which can cause overheat and damage to the
three way catalytic converter, it makes the malfunction indicator lamp (MIL) flash as long as misfire occurs at
that rate.
After that, however, when the misfire rate drops, MIL remains ON until it has been judged as normal 3 times
under the same driving conditions.
Also, when ECM detects a misfire (misfire rate per 1000 revolutions) which will not cause damage to three way
catalytic converter but can cause exhaust emission to be deteriorated, it makes MIL light according to the 2 driv-
ing cycle detection logic.

10) Disengage clutch (1) (to lighten starting load on engine) for
M/T vehicle, and depress accelerator pedal (2) all the way to
make throttle fully open.
11) Crank engine with fully charged battery, and read the highest
pressure on compression gauge.
Compression pressure specification
12) Carry out Steps 9) through 11) on each cylinder to obtain 4
readings.
13) After checking, install spark plugs and ignition coil assem-
blies (1) with high-tension cord (2).
14) Connect ignition coil couplers (3).
15) Connect fuel injector wires (4) at the coupler.
16) Check cylinder head upper cover gasket for deterioration and
then install it into groove of cylinder head upper cover (1)
securely.
17) Install cylinder head upper cover with gasket on to cylinder
head cover.
18) Connect accelerator cable (2) to clamp (3) (For left hand
steering vehicle only).
NOTE:
For measuring compression pressure, crank engine at
least 250 rpm by using fully charged battery.
If check results are below the limit valve, check instal-
lation condition for special tool.
