Harness connectors F30, M63

Harness for open or short between ECM relay and mass air flow sensor

Harness for open or short between mass air flow sensor and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
5. CHECK MAFS GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between mass air flow sensor terminal 3 and ECM terminal 73.
Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG

6. CHECK MAFS INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check harness continuity between mass air flow sensor terminal 4 and ECM terminal 54. Refer to Wiring
Diagram.
2. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 7.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
7. CHECK EGR VOLUME CONTROL VALVE FUNCTION
With CONSULT-II
1. Reconnect all harness connectors disconnected.
2. Remove EGR volume control valve from cylinder head.
3. Turn ignition switch ON.
4. Perform “EGR VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-II. Check that EGR volume control
valve shaft moves smoothly forward and backward according to the valve opening.
NOTE:
When installing the EGR volume control valve, make sure that the shaft is in the same position before
checking.
Without CONSULT-II
1. Reconnect all harness connectors disconnected.
2. Remove EGR volume control valve from cylinder head.
3. Turn ignition switch ON and OFF.
4. Check that EGR volume control valve shaft moves smoothly for-
ward and backward according to the ignition switch position.
NOTE:
When installing the EGR volume control valve, make sure that
the shaft is in the same position before checking.
OK or NG
OK >> GO TO 8.
NG >> Check EGR volume control valve and its circuit. Refer to
EC-1196, "
Diagnostic Procedure" .
8. CHECK INTAKE AIR TEMPERATURE SENSOR
Refer to EC-1092, "
Component Inspection" .
OK or NG
OK >> GO TO 9.
NG >> Replace mass sir flow sensor (with intake air temperature sensor).Continuity should exist.
