Disconnect the NVLD electrical harness connector.
Measure the resistance between the (Z1) Ground circuit and ground.
Is the resistance below 5.0 ohms?

All

Yes

Perform POWERTRAIN VERIFICATION TEST VER - 5.

Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K107) NVLD Switch Signal circuit from the NVLD
electrical harness connector to the appropriate terminal of special tool # 8815.
Is the resistance below 5.0 ohms?

All

Yes

→ NOTE: Before continuing, check the PCM harness connector

terminals for corrosion, damage or terminal push out. Repair as
necessary. Replace and program the Powertrain Control Module
in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

→ Repair the open in the (K107) NVLD Switch Signal circuit.

P0453-NVLD PRESSURE SWITCH SENSE CIRCUIT HIGH —

Continued

Symptom:

P0456-EVAP SYSTEM SMALL LEAK

When Monitored and Set Condition:

P0456-EVAP SYSTEM SMALL LEAK

When Monitored:

Ignition off. Fuel Level less than 88%. Ambient Temperature between

4°C to 43°C (39°F to 109°F)

Set Condition:

Due to temperature changes a vacuum is created in the fuel tank and

EVAP system. With the EVAP system sealed, the PCM monitors the NVLD switch. If the
NVLD switch does not close within a calibrated amount of time an error is detected.

POSSIBLE CAUSES

INTERMITTENT CONDITION

VISUAL AND PHYSICAL INSPECTION

EVAPORATIVE EMISSION LEAK DETECTION

TEST

ACTION

APPLICABILITY

NOTE: The difference in ambient temperature, outside temp VS shop temp,
may conceal a leak, it is best to perform this test after the vehicle’s
temperature has stabilized in the work area.
Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

→ Go To 4

Perform a visual and physical inspection of the entire Evaporative Emission system.
Check for the following conditions:
- Holes or cracks
- Loose seal points
- Evidence of damaged components
- Incorrect routing of hoses and tubes
- Fuel Cap gasket seal
Were any of the above conditions found?

All

Yes

→ Repair as necessary.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

TEST

ACTION

APPLICABILITY

NOTE: A thorough visual inspection of the Evap system hoses, tubes, and
connections may save time in your diagnosis. Look for any physical damage
or signs of wetness at connections. The strong smell of fuel vapors may aid
diagnosis also.
Use the Miller Tool #8404 Evaporative Emissions Leak Detector (EELD).
Connect the SMOKE supply tip (black hose) to the service port, (if equipped) or
install the #8404-ADP service adapter in the NVLD filter line..
Set the smoke/air control switch to SMOKE.
Block the vent hose of the EVAP Canister.
NOTE: The flow meter indicator ball will not move at this point.
Press the remote smoke/air start button.
NOTE: Ensure that smoke has filled the EVAP system by continuing to press
the remote smoke/air start button, remove the vehicle fuel cap, and wait for
the smoke to exit. Once smoke is indicated reinstall the fuel cap.
NOTE: For optimal performance, introduce smoke into the system for an
additional 60 seconds; continue introducing smoke at 15 second intervals,
as necessary.
While still holding the remote smoke/air start button, use the white light (#8404-
CLL) to follow the EVAP system path, and look for the source of the leak indicated by
exiting smoke.
If a leak is concealed from view (i.e., top of fuel tank), release the remote smoke/air
start button, and use the ultraviolet (UV) black light #8404-UVL and the yellow
goggles 8404-20 to look for residual traces of dye that are left behind by the smoke.
The exiting smoke deposits a residual fluid that is either bright green or bright
yellow in color when viewed with a UV light.
NOTE: Carefully inspect the vent side of the EVAP Canister. Due to the
filtering system in the canister the smoke or dye may or may not be visual.
Introducing smoke into the filtered side of the canister may assist in
locating the leak.
Was a leak found?

All

Yes

→ Repair or replace the leaking component as necessary.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

→ Go To 4

WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
Review the DRBIII

t Freeze Frame information. If possible, try to duplicate the

conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
NOTE: A loose gas cap could have caused this DTC to set. Make sure gas cap
is tight and in good condition. Ensure the gas cap meets OEM specifications.
Perform a visual and physical inspection of the entire Evaporative Emission system.
Check for the following conditions:
- Holes or cracks
- Loose seal points
- Evidence of damaged components
- Incorrect routing of hoses and tubes
- Fuel Cap gasket seal
Were any of the above conditions found?

All

Yes

→ Repair as necessary.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

→ Test Complete.

TEST

ACTION

APPLICABILITY

NOTE: After the PCM has determined the leak test inconclusive and sees an
increase in fuel level, the PCM will request the GAS CAP indicator on to
inform the customer that the gas fill cap is loose or off.
Ignition on, engine not running.
With the DRBIII

t, read DTCs and record the related Freeze Frame data.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 6.

Perform a visual and physical inspection of the Fuel Fill Cap and the fill tube.
Check for the follow conditions:
- Improper installation of Fuel Fill Cap
- Loose or missing Fuel Filler Cap
- Holes or cracks
- Damaged Locking tabs on Cap and/or fill tube
- Damaged seal points on Cap and/or fill tube
- Fuel Fill Cap gasket seal
Were any of the above conditions found?

All

Yes

→ Repair or replace the fuel fill cap as needed. Ensure proper fuel

fill cap installation. Once the repair is complete continue to step
