Customer states:
 MIL on.
Workshop findings:
The following DTC is stored in the engine control module (ECM), J623 (address word 0001):
 DTC P045600 (EVAP System Leak Detected NVLD (very small leak)).
 Drivability is not affected.
Technical Background
The NVLD pressure switch may erroneously detect a very small leak.
Production Solution
New NVLD pressure switches and NVLD filters in production.
Service
1. Ensure that DTC P045600 (EVAP System Leak Detected NVLD (very small leak)) is stored in the
engine control module (ECM), J623 (address word 0001). If DTC P045600 is not present, this bulletin
does not apply.
2. Replace the NVLD pressure sensor G400 and the NVLD filter with the latest part number available
(Figure 1).

Note:
Read the following information for correct installation of the NVLD switch grommet. The following
information applies only if the sensor is directly installed into the charcoal canister.
3. Align the grommet and sensor outer
edges (Figure 2).
Figure 2. Align the grommet and sensor outer edges.
4. To aid installation, wrap several (~10)
layers of vinyl tape behind the
grommet to ensure that it does not slip
during installation (Figure 3 and
Figure 4).

5. Apply a small amount of grease to
create a film on the outer surface of
the grommet before installing the
sensor (Figure 5).

6. When the sensor and grommet have
been correctly installed, the grommet
and canister will be flush (Figure 6). At
this point, the vinyl tape can be
removed (or it can be left in place).
Figure 6. Correctly-installed sensor and grommet.
7. An incorrectly-installed sensor and
grommet (Figure 7) can cause an
EVAP leak and repeat failures. Issues
can occur when the NVLD switch is
pressed too far into the canister, then
pulled back out in an attempt to align
the NVLD switch with the mounting
holes.
Do not apply any lubricant between
the sensor and the grommet.
Figure 7. Plastic port extending past the grommet (A) causing
installation issues (B).
Note:
Due to the functionality of the new tank leak diagnostic system (NVLD), it is not possible to check the
system using a basic setting or an output diagnostic test mode like the previously-used LDP system.
Note:
Always use a VIN to search parts in ETKA.
