Possible Causes

NVLD SWITCH OPERATION

(K107) NVLD SWITCH SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE

(K107) NVLD SWITCH SIGNAL CIRCUIT SHORTED TO (K106) NVLD SOL CONTROL CIRCUIT NVLD ASSEMBLY

(Z1) GROUND CIRCUIT OPEN

(K107) NVLD SWITCH SIGNAL CIRCUIT OPEN

PCM

DIAGNOSTIC PROCEDURE - P0453-NVLD PRESSURE SWITCH SENSE CIRCUIT HIGH

TEST ACTION
1 Start the engine.
Allow the engine to idle.
Using the DRBIII®, perform the NVLD FORCED MONITOR TEST.
Monitor the NVLD Switch state.
NOTE: As the test runs, the NVLD Switch should go from an OPEN state to a CLOSED state and then return to OPEN when the test is complete.

Did the NVLD Switch operate as described above?
  1. Yes --> Refer to the INTERMITTENT CONDITION  symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 2
2 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Ignition on, engine not running.
Measure the voltage on the (K107) NVLD Switch Signal circuit in the NVLD electrical harness connector.
Is the voltage above 5.5 volts?
  1. Yes --> Repair short to battery voltage in the (K107) NVLD Switch Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 3
3 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Measure the resistance between the (K107) NVLD Switch Signal circuit and (K106) NVLD Sol Control circuit in the NVLD electrical harness connector.
Is the resistance below 5.0 ohms?
  1. Yes --> Repair the (K107) NVLD Switch Signal circuit shorted to the (K106) NVLD Sol Control circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 4
4 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Using a jumper wire, jumper across the NVLD Switch Signal circuit and the Ground circuit.
Monitor the NVLD Switch state on the DRBIII®.
Does the Switch change from OPEN to CLOSED?
  1. Yes --> Replace the NVLD Assembly.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 5
5 Turn the ignition off.
Disconnect the NVLD electrical harness connector.
Measure the resistance between the (Z1) Ground circuit and ground.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 6
  2. No --> Repair the open in the (Z1) Ground circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
6 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 TERMINALS 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?
  1. 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 - NGC .

  2. No --> Repair the open in the (K107) NVLD Switch Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
