Others

• The ECM controls the electric throttle control actuator in regulating the throttle opening in order 

for the idle position to be within +10 degrees.

• The ECM regulates the opening speed of the throttle valve to be slower than the normal con-

dition. So, the acceleration will be poor. 

NOTE:
If throttle position sensor1 and 2 malfunction at the same time conducts following control.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed 

opening (approx. 5 degrees) by the return spring.

P0300, P0301, P0302, P0303, P0304 MISFIRE

DTC Description

INFOID:0000000010775172

DTC DETECTION LOGIC

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank-
shaft position (CKP) sensor signal to vary, ECM can determine that a misfire is occurring.

The misfire detection logic consists of the following two conditions.
1.

One Trip Detection Logic (Three Way Catalyst Damage)
On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to over-
heating, the MIL will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions
for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.If
another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.

2.

Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only
light when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sen-
sor signal every 1,000 engine revolutions.

A misfire malfunction can be detected in any one cylinder or in multiple cylinders.

POSSIBLE CAUSE

• Improper spark plug
• Insufficient compression
• Incorrect fuel pressure
• The fuel injector circuit is open or shorted.
• Fuel injector
• Intake air leakage
• The ignition signal circuit is open or shorted.
• Lack of fuel
• Signal plate
• A/F sensor 1
• Mass air flow sensor
• Incorrect PCV hose connection
