DIAGNOSTIC TROUBLE CODE (DTC) – P0300 MULTIPLE CYLINDER MISFIRE
System Description
The Engine Control Module (ECM) monitors the crank-
shaft and camshaft positions to detect if the engine is
misfiring. The ECM looks for a quick drop in crankshaft
speed. This test is executed in blocks of 100 engine rev-
olution tests. It may take between one to several tests to
store a Diagnostic Trouble Code (DTC) and illuminate
the Malfunction Indicator Lamp (MIL). Under light misfire
conditions, it may also take more than one trip to set a
DTC. Severe misfire will flash the MIL, indicating that
catalyst damage is possible.
Conditions for Setting the DTC
Emission threshold is 3.0% for manual transaxle.
20 engine cycles have occurred since cranking has
started.
A/C compressor clutch has not just engaged or disen-
gaged.
Engine load and engine speed are in a detectable re-
gion and are at or above zero torque.
Camshaft Position (CMP) sensor is in synchroniza-
tion.
Electric Exhaust Gas Recirculation (EEGR) flow
diagnostic is not in progress.
Fuel level is greater than or equal to 20% of rated
tank capacity.
Decel Fuel Cutoff (DFCO) not active.
Fuel is not shutoff from high engine speed of 6500
rpm for manual transaxle vehicle.
Fuel is not shutoff at 255 km/h (158 mph).
Throttle position change is less than 3% per 125 ms.
Vehicle has not encountered an abusive engine
speed of 7000 rpm.Crankshaft speed patters are normal.
Throttle position is less than 4% when vehicle speed
is greater than 10 km/h (6 mph).
Engine speed is between 800 and 4500 rpm.
Vehicle voltage is between 11 and 16 volts.
Engine Coolant Temperature (ECT) is between –7°C
(20°F) and 120°C (248°F).
The engine speed is less than or equal to 1800 rpm or
the crank angle sensing error has not been learned.
There is the correct ratio between Crankshaft Posi-
tion (CKP) sensor pulses and CMP sensor pulses.
DTCs P0106, P0107, P0108, P0117, P0118, P0122,
P0123, P0320, P0337, P0341, P0342 and P0502 are
not set.
Action Taken when the DTC Sets
The malfunction Indicator Lamp (MIL) will blinking.
The ECM will record operating conditions at the time
the diagnostic fails. The information will be stored in
the Freeze Frame and failure records buffers.
A history DTC is stored.
Conditions for Clearing the MIL/DTC
A history DTC will clear after 40 consecutive warm up
cycles without a fault.
DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent can also be the result of a defective re-
luctor wheel. Remove the CKP sensor and inspect the
reluctor wheel through the sensor mount hole. Check for
porosity and the condition of wheel. If the DTC is inter-
mittent refer to “Symptoms Diagnosis” in this section.

Emission related.
“Armed” after two trip with a fail.
“Disarmed” after one trip with a pass.
MIL on if failure is detected in three consecutive trips.
Stores a History DTC on the third consecutive with a
fail (The DTC will be armed after the second fail).
Stores a Freeze Frame on the third consecutive trip
with a fail (if empty).
Conditions for Clearing the MIL/DTC
