Dtc P0100: Mass Or Volume Air Flow Circuit 1A-296 - Suzuki Grand Vitara 2011 Manual

DTC P0100: Mass or Volume Air Flow Circuit
NOTE
• Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
• If the fault is present, the Injection warning light (gravity 1 warning light) is lit.
• Use service wire for all operations on the ECM connectors.
• Priorities when dealing with a number of faults:
As a priority, deal with fault "DTC P0697: Sensor Reference Voltage 3 Circuit: For Diesel Engine
Model" if the fault is present or stored.
Wiring Diagram
For wiring circuit and connector number, refer to "A-5 Engine and A/C Control System Circuit Diagram (DSL) in
Section 9A".

D2
Troubleshooting for CC1: Short circuit to +12 V
Check the MAF sensor assembly with IAT sensor connections.
Check the ECM connections.
Repair if necessary.
Check the continuity and the insulation against +12 V of the following connections:
• Between "C13-2" wire of MAF sensor assembly with IAT sensor connector and "C86-24" terminal of ECM
connector
• Between "C13-6" wire of MAF sensor assembly with IAT sensor connector and "C86-12" terminal of ECM
connector
• Between "C13-5" wire of MAF sensor assembly with IAT sensor connector and "C86-47" terminal of ECM
connector
If the fault is still present, replace the MAF sensor assembly with IAT sensor.
Troubleshooting for CO0: Open circuit or short circuit to vehicle body ground
Check there is a +5 V supply on "C13-5" wire of the MAF sensor assembly with IAT sensor connector.
Repair if necessary.
Check the MAF sensor assembly with IAT sensor connections.
Check the ECM connections.
Repair if necessary.
Check the continuity and insulation from vehicle body ground between:
• Between "C13-2" wire of MAF sensor assembly with IAT sensor connector and "C86-24" terminal of ECM
connector
• Between "C13-5" wire of MAF sensor assembly with IAT sensor connector and "C86-47" terminal of ECM
connector
• Between "C13-6" wire of MAF sensor assembly with IAT sensor connector and "C86-12" terminal of ECM
connector
• Between "C13-4" wire of MAF sensor assembly with IAT sensor connector and "E33-6" terminal of main
mounting connector
Repair if necessary.
If the fault is still present and remains present, replace the MAF sensor assembly with IAT sensor.
