CHECK TURBOCHARGER BOOST SENSOR

1. Turn ignition switch OFF.

2. Remove turbocharger boost sensor with its harness connector.

3. Install pressure pump (A) to turbocharger boost sensor (1).

CAUTION:

When insert a pressure pump hose to the sensor, be careful

to the damage of the sensor housing.

5. Check the voltage between ECM harness connector terminals

as per the following conditions.

NOTE:

• Always calibrate the pressure pump gauge when using it.

• Inspection should be done at room temperature [10 - 30

°C (50 - 86°F)].

DTC Logic

INFOID:0000000012197881

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.

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

PERFORM DTC CONFIRMATION PROCEDURE-I

1. Start engine and warm it up to normal operating temperature.

2. Turn ignition switch OFF and wait at least 10 seconds.

3. Restart engine and let it idle for about 15 minutes.

4. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE-II

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Start engine and drive the vehicle as per the similar conditions to (1st trip) Freeze Frame Data for a certain

time. Refer to the table below.

Hold the accelerator pedal as steady as possible.

The similar conditions to (1st trip) Freeze Frame Data means the vehicle operation that the following con-

ditions should be satisfied at the same time.

CAUTION:

Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws when

driving.

The time to driving varies according to the engine speed in the freeze frame data.

3. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

CHECK FOR INTAKE AIR LEAK AND PCV HOSE

1. Start engine and run it at idle speed.

2. Listen for the sound of the intake air leak.

3. Check PCV hose connection.
Is intake air leak detected?

YES

>> Discover air leak location and repair.

>> GO TO 3.

CHECK FOR EXHAUST SYSTEM CLOGGING

Stop engine and visually check exhaust tube, three way catalyst and muffler for dents.
Is the inspection result normal?

YES-1 >> With CONSULT: GO TO 4.

YES-2 >> Without CONSULT: GO TO 5.

>> Repair or replace it.
