DIAGNOSTIC TROUBLE CODE PROCEDURES
DIAGNOSIS
Required Special Tools:
⦆
MB991958: Scan tool (M.U.T.-III Sub Assembly)
⦆
MB991824: V.C.I.
⦆
MB991827: USB Cable
⦆
MB991910: Main Harness A
STEP 1. Using scan tool MB991958, check data list item 10:
Mass Airflow Sensor.

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.
(1)
Connect scan tool MB991958 to the data link connector.
(2)
Start the engine and run at idle.
(3)
Set scan tool MB991958 to the data reading mode for item
10, Mass Airflow Sensor.
(4)
Warm up the engine to normal operating temperature: 80°C
to 95°C (176°F to 203°F).
⦆
The standard value during idling should be between 1,350
and 1,670 millivolts.
⦆
When the engine is revved, the mass airflow rate should
increase according to the increase in engine speed.
(5)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the sensor operating properly?
YES:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.
NO:
Go to Step 2.
STEP 2. Check harness connector A-07 at the mass airflow
sensor and harness connector B-11 at the ECM for damage.
Q:Is the harness connector in good condition?
YES:
Go to Step 3.
NO:
Repair it. Refer to GROUP 00E, Harness Connector
Inspection P.00E-2. Then go to Step 5.
STEP 3. Check for the continuity between the mass airflow
sensor connector A-07 and the ECM connector B-11.
(1)
Disconnect the mass airflow sensor connector A-07 and the
ECM connector B-11.

(2)
Check for the continuity between the mass airflow sensor
connector A-07 (terminal No. 4) and the ECM connector B-11
(terminal No. 88).
⦆
Should be less than 2 ohms.
Q:Does continuity exist?
YES:
Go to Step 4.
NO:
Repair it. Then go to step 5.
STEP 4. Replace the mass airflow sensor.
(1)
Replace the mass airflow sensor.
(2)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.
(3)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0102 set?
YES:
Replace the ECM. When the ECM is replaced, register
the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 5.
NO:
The inspection is complete.
STEP 5. 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 24 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0103 set?
YES:
Retry the troubleshooting.
NO:
The inspection is complete.
