NGcGO TO 6.
6 DETECT MALFUNCTIONING PART
Check the following.
+Harness connectors E230, F12
+Harness for open or short between mass air ¯ow sensor and ECM
cRepair open circuit or short to ground or short to power in harness or connectors.
DTC 0102 MASS AIR FLOW SENZD30DDTi
Diagnostic Procedure (Cont'd)
EC-4051

7 CHECK SHIELD CIRCUIT
1. Disconnect harness connectors E230, F12.
2. Check harness continuity between harness connector F12 terminal 5 and ground.
Refer to Wiring Diagram.
Continuity should exist.
3. Also check harness for short to power.
OK or NG
OKcGO TO 9.
NGcGO TO 8.
8 DETECT MALFUNCTIONING PART
Check the following.
+Joint connector-4
+Harness for open or short between harness connector F12 and ground
cRepair open circuit or short to power in harness or connectors.
9 CHECK MASS AIR FLOW SENSOR
1. Reconnect harness connectors disconnected.
2. Start engine and warm it up to normal operating temperature.
3. Check voltage between ECM terminal 35 (Mass air ¯ow sensor signal) and ground.
SEF400YA
4. If the voltage is out of speci®cation, proceed the following.
a. Check for the cause of uneven air ¯ow through mass air ¯ow sensor. Refer to the following.
+Crushed air ducts
+Malfunctioning seal of air cleaner element
+Uneven dirt of air cleaner element
+Improper speci®cation of intake air system parts
b. If NG, repair or replace malfunctioning part and perform steps 2 to 4 again.
5. Turn ignition switch ªOFFº.
6. Disconnect MAFS harness connector and connect it again.
7. Perform steps 2 and 3 again.
OK or NG
OKcGO TO 10.
NGcReplace mass air ¯ow sensor.
10 CHECK INTERMITTENT INCIDENT
