DTC Logic
INFOID:0000000006496328
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 MI 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 MI will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MI will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MI will remain on.
If another misfire condition occurs that can damage the TWC, the MI 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 MI will only light
when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sensor
signal every 1,000 engine revolutions.
A misfire malfunction can be detected on any one cylinder or on multiple cylinders.
DTC CONFIRMATION PROCEDURE

generated between the spark plug and the grounded metal por-
tion.
CAUTION:
• Do not approach to the spark plug and the ignition coil
within 50 cm (19.7 in). Be careful not to get an electrical
shock while checking, because the electrical discharge
voltage becomes 20 kV or more.
• It might cause to damage the ignition coil if the gap of more than 17 mm (0.66 in) is taken.

Diagnosis Procedure
INFOID:0000000006496331
1.
CHECK GROUND CONNECTION
1.
Turn ignition switch OFF.
2.
Check ground connection E21 and E38. Refer to Ground Inspection in
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace ground connection.
2.
CHECK KNOCK SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1.
Disconnect knock sensor harness connector.
2.
Disconnect ECM harness connector.
3.
Check the continuity between knock sensor harness connector and ECM harness connector.
4.
Also check harness for short to ground and short to power.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.
CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Check the continuity between knock sensor harness connector and ECM harness connector.
DTC No.

1.
CHECK KNOCK SENSOR
1.
Turn ignition switch OFF.
2.
Disconnect knock sensor harness connector.
3.
Check resistance between knock sensor terminals as follows.
NOTE:
It is necessary to use an ohmmeter which can measure more than 10 M
Ω
.
CAUTION:
Do not use any knock sensors that have been dropped or physically damaged. Use only new ones.

Crankshaft position sensor
(POS) circuit
• The crankshaft position sensor (POS) signal
is not detected by the ECM during the first
few seconds of engine cranking.
• The proper pulse signal from the crankshaft
position sensor (POS) is not sent to ECM
while the engine is running.
• The crankshaft position sensor (POS) signal
is not in the normal pattern during engine
running.
• Harness or connectors
[Crankshaft position sensor (POS) circuit
is open or shorted.]
(Refrigerant pressure sensor circuit is
shorted.)
(Accelerator pedal position sensor 2 cir-
cuit is shorted.)
