2012 AND NEWER; EVAP LEAK DTC P0442, P0455, P0456 INFORMATION
APPLIED VEHICLES:
2012 and newer Infiniti vehicles
SERVICE INFORMATION
Example
All model year 2012 and newer Infiniti vehicles have a warning indicator in
the instrument area to alert the driver of a loose fuel cap (see example in
Figure 1).
Figure 1
•
If a vehicle displays a Loose Fuel Cap warning light or message,
the driver should safely stop the vehicle and make sure the fuel fill cap is installed correctly.
•
Make sure the customer is informed of the proper fuel fill cap installation.
•
Customers should refer to their vehicle’s Owner’s Manual for specific details on the “Loose Fuel Cap”
warning system and fuel fill cap installation.
If a fuel fill cap is left loose for multiple trips, DTCs will be stored and the MIL will illuminate.
•
If one or more of these EVAP leak DTCs are stored (P0442, P0455, P0456), a loose fuel fill cap may
be the cause.
If a loose fuel fill cap is not the cause of EVAP system DTCs, use the following resources to perform
diagnostics and confirm the cause.
ASIST:
• Appropriate Service Manual diagnostic procedures
• Applicable Technical Service Bulletins (TSB).
Leak Test:
• With CONSULT-III plus - WORK SUPPORT >> EVAP SYSTEM CLOSE.
NOTE: Use Essential Tool J-42909 or equivalent to pressurize the EVAP system.
• With a “Smoke” leak detection machine. Refer to the machine’s Operator’s Manual for proper use.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe
that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti dealer to determine if this
applies to your vehicle.
