DTC Description

INFOID:0000000010986358

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (TP sensor 1 circuit is open or shorted.)
• Electric throttle control actuator (TP sensor 1)

FAIL-SAFE

• 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 condition. So, the

acceleration will be poor.

P0300, P0301, P0302, P0303, P0304 MISFIRE

P0300, P0301, P0302, P0303, P0304 MISFIRE

DTC Description

INFOID:0000000010986361

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 (POS) 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, when a misfire condition occurs that can damage the three way catalyst (TWC) due to
overheating, 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 on any one cylinder or on multiple cylinders.

POSSIBLE CAUSE

• Improper spark plug
• Insufficient compression
• Incorrect fuel pressure
• Fuel Injector circuit is open or shorted
• Fuel injector
• Intake air leak
• Ignition signal circuit is open or shorted
• Lack of fuel
• Signal plate
• A/F sensor 1
• Incorrect PCV hose connection
