•
When Monitored:
Engine running.
•
Set Condition:
The PCM detects a short in the NVLD Canister vent solenoid circuits. One Trip Fault. Three good trips to turn
off the MIL.
Possible Causes
(K106) NVLD SOLENOID CONTROL CIRCUIT SHORTED TO GROUND
NVLD ASSEMBLY
PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.
ACTIVE DTC
Ignition on, engine not running.
With a scan tool, read DTCs.
Is the DTC active at this time?
Yes
>> Go To 2
No
>> Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.
NVLD SOLENOID
Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Measure the resistance of the NVLD Solenoid Coil.
Is the resistance between 7.5 to 8.5 ohms?
Yes
>> Go To 3
No
>> Replace the NVLD Assembly.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)

3.
(K106) NVLD SOLENOID CONTROL CIRCUIT SHORTED TO GROUND
Disconnect the C3 PCM harness connector.
Measure the resistance between ground and the (K106) NVLD Sole-
noid Control circuit in the NVLD electrical harness connector.
Is the resistance below 100 ohms?
Yes
>> Repair the short to ground in the (K106) NVLD Solenoid
Control circuit.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
No
>> Go To 4
4.
PCM
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal
push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and
Ground circuits.
Were there any problems found?
Yes
>> Repair as necessary.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Replace and program the Powertrain Control Module per Service Information.
