STEP 2. Using scan tool MB991958, check data list item 5: 
Intake Air Temperature Sensor.
(1) Turn the ignition switch to the "ON" position.
(2) Set scan tool MB991958 to the data reading mode for item 

5, Intake Air Temperature Sensor.

• The intake air temperature and temperature shown with 

the scan tool should approximately match.

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : Go to Step 3.
NO :  Refer to DTC P0111 

− Intake Air Temperature Circuit

P.13A-171

.

STEP 3. Using scan tool MB991958, check data list item 6: 
Engine Coolant Temperature Sensor.
(1) Turn the ignition switch to the "ON" position.
(2) Set scan tool MB991958 to the data reading mode for item 

6, Engine Coolant Temperature Sensor.

• The engine coolant temperature and temperature 

shown with the scan tool should approximately match.

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : Go to Step 4.
NO :  Refer to DTC P0116 

− Engine Coolant Temperature

STEP 4. Using scan tool MB991958, check data list item 8: 
Manifold Absolute Pressure Sensor.
(1) Turn the ignition switch to the "ON" position.
(2) Set scan tool MB991958 to the data reading mode for item 

8, Manifold Absolute Pressure Sensor.

• When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).

• When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).

• When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 

in.Hg).

• When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 

in.Hg).

(3) Start the engine.

• When the engine is idling, 16 − 36 kPa (4.7 − 10.6 

in.Hg).

• When the engine is suddenly revved, manifold absolute 

pressure varies.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : Go to Step 5.
NO :  Refer to DTC P0106 

− Manifold Absolute Pressure 

Circuit Range/Performance Problem 

P.13A-139

, DTC 

P0107 

− Manifold Absolute Pressure Circuit Low 

Input 

P.13A-148

, DTC P0108 

− Manifold Absolute 

Pressure Circuit High Input 

P.13A-156

.

STEP 5. Check the injector.
(1) Disconnect the injector connector B-101, B-120, B-103 and 

B-116.

(2) Measure the resistance between each injector side 

connector terminal No. 1 and No. 2.

Standard value: 10.5 

− 13.5 ohms [at 20°C (68°F)]

Q: Is the measured resistance between 10.5 and 13.5 ohms 

[at 20

°C (68°F)]?

YES : Go to Step 6.
NO :  Replace the injector. Then go to Step 8.

STEP 6. Check the fuel pressure.
Refer to On-vehicle Service 

− Fuel Pressure Test 

P.13A-868

.

Q: Is the fuel pressure normal?

YES : Go to Step 7.
NO :  Repair it. Then go to Step 8.

STEP 7. Replace the injector.
(1) Replace the injector.
(2) Carry out a test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle − Pattern 21 

P.13A-11

.

(3) Check the diagnostic trouble code (DTC).
Q: Is DTC P0172 set?

YES : Replace the ECM. When the ECM is replaced, 

register the ID code. Refer to GROUP 42B, Diagnosis 
− ID Code Registration Judgment Table <Vehicles 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM> 

P.42C-10

. Then go to Step 8.

NO :  The inspection is complete.

STEP 8. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle − Pattern 21 

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0172 set?

YES : Retry the troubleshooting.
NO :  The inspection is complete.
