SERVICE PROCEDURE
IMPORTANT: Before disconnecting any hose, make sure you mark the hose so it can
be correctly re-installed later. If a hose is incorrectly re-installed, the MIL will come
on.
1. Disconnect the vacuum hose from the EVAP System Pressure Sensor (see Figure 3).
CAUTION: The vacuum hose must be disconnected from the Pressure Sensor to prevent it
from being damaged.
Figure 3
2. Disconnect the Purge hose from the EVAP canister port labeled “Purge” (see Figure 3).
3. Disconnect the hose from the EVAP Purge Volume Control Valve (or Purge Cut Valve, if
equipped). Refer to Figures 1, 2, and 4 to determine which hose to disconnect based
on the type of Purge Volume Control Valve on the vehicle (i.e., duty cycle or step motor
type).
IMPORTANT: Before disconnecting any hose, make sure you mark the hose so it can be
correctly re-installed later. If a hose is incorrectly re-installed, the MIL will come on.
B. Cover the EVAP System Pressure Sensor hose with your finger, then blow air
through the Purge hose/EVAP system piping to remove charcoal particles
C. Repeat steps A and B until ALL charcoal particles are removed.
If all charcoal particles cannot be removed from the EVAP system piping using this
method, remove the piping from the vehicle. Then blow air through the piping while
moving it in different positions until all particles are removed. If this does not work,
replace the underbody piping.
5. Inspect the following components (refer to Figures 1 and 2) for charcoal particles. If
charcoal particles are found, carefully remove the particles from the component(s) and
the hoses that connect to them.
• Purge Volume Control Valve
• Purge Cut Valve (if equipped)
• EVAP System Pressure Sensor
• Vent Control Valve
• Vacuum Cut Valve Bypass Valve
• Vacuum Cut Valve
• Water Separator (and associated hoses)
IMPORTANT REMINDER: Before disconnecting any hose, make sure you mark
the hose so it can be correctly re-installed later. If a hose is incorrectly reinstalled,
the MIL will come on.
NOTE: It is very important to remove all charcoal particles as it only takes a small
amount of particles to store DTCs and cause the MIL to turn on. If you cannot remove
all charcoal particles, replace the contaminated (un-cleanable) component(s).
6. Re-assemble the EVAP system.
7. Erase all stored DTCs.
8. Road test the vehicle until the EVAP SRT shows “Complete”, then re-check for any
stored DTCs.
CLAIMS INFORMATION
For replacement of the EVAP canister and EVAP system charcoal debris
cleaning/removal, submit a Primary Failed Part (PP) line claim using the following
claims coding. To claim for diagnostic time(s) associated with the DTC code(s)
and/or the replacement of those components that have been rendered non-functional
due to charcoal contamination, reference the current Nissan "Warranty Flat Rate
Manual" and use the indicated Op Codes and FRTs
