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 of each cylinder.
The ECM counts the number of times from the engine speed change rate, indicating that misfire has oc-
curred. When the misfire rate equals to or exceeds the count, indicating that the engine condition has deteri-
orated, the CHK ENG is illuminated.
If the misfire rate is high enough and the driving conditions causes the catalyst to overheat, the CHK ENG
blinks when the misfire occurs.
HINT:

For any particular 200 revolutions of engine, misfiring which could result in overheating of catalyst is
detected. This cause CHK ENG to blink (1 trip detection logic).

For any particular 1,000 revolutions of engine, misfiring which could result in a deterioration of emis-
sions is detected. This cause CHK ENG to illuminate (2 trip detection logic).

corded, it is indicated that the misfires were detected and recorded at different times.

(a)Read the DTC using the hand±held tester. Result:
Display (DTC output)Proceed to
Only ºP0300, P0301, P0302, P0303 and/or P0304º are outputA
ºP0300, P0301, P0302, P0303 and/or P0304º and other DTCs are outpu\

HINT:
If any other codes besides ºP0300, P0301, P0302, P0303 and/or P0304º are output, perform the trouble-
shooting for those DTCs first.
BGO TO RELEVANT DTC CHART(See page 05±16)

2CHECK WIRE HARNESS, CONNECTOR AND VACUUM HOSE IN ENGINE ROOM
(a)Check the connection of the wire harness and the connector.
(b)Check the vacuum hose for disconnection, blockage and break. NGREPAIR OR REPLACE, THEN CONFIRM THATTHERE IS NO MISFIRE
OK
3READ VALUE OF HAND±HELD TESTER(NUMBER OF MISFIRE)
(a)Connect the hand±held teste to the DLC3.
(b)Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(c)Start the engine.
(d)Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL/CYL#1 ± CYL#4º.
(e)Read the number of misfire on the hand±held tester.
