This TSB applies to all 2007-2012 Infiniti vehicles in cases where the IAVL (intake air volume learn) will not complete when using CONSULT.
A. While the engine is running, disconnect the MAF sensor for 10-15 seconds until the MIL illuminates (P0102 or P010C), and then reconnect the MAF before performing Intake Air Volume Learn.
NOTE: If the vehicle has two MAF sensors, disconnect only one in the prior step and leave the second one connected.
The engine may stop running when idle reduction occurs. Reconnect the MAF sensor and continue to Step B.
NOTE: If P0102 or P010C were not stored when DTC was checked, repeat Step A until idle is reduced.
B. Clear any DTCs that may have set during MAF disconnect.
C. Perform IAVL.
D. Confirm that idle is now within specifications for the model and year of the vehicle.
(Refer to the electronic service manual for the procedure to set IAVL and for idle specifications).
