Possible Causes

GOOD TRIP EQUAL TO ZERO

EVAP PURGE SOLENOID OPERATION

(K52) EVAP PURGE SOL CONTROL CIRCUIT OPEN

(K52) EVAP PURGE SOLENOID CONTROL CIRCUIT SHORTED TO GROUND

(K108) EVAP PURGE SOL RETURN CIRCUIT OPEN

(K108) EVAP PURGE SOL RETURN CIRCUIT SHORTED TO GROUND

POWERTRAIN CONTROL MODULE

DIAGNOSTIC PROCEDURE - P0443-EVAP PURGE SOLENOID CIRCUIT

TEST ACTION
1 Ignition on, engine not running.
With the DRBIII®, read DTCs and record the related Freeze Frame data.
Is the Good Trip Counter displayed and equal to zero?
  1. Yes --> Go To 2
  2. No --> Refer to the INTERMITTENT CONDITION  symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
2 Turn the ignition off.
Disconnect the EVAP Purge Solenoid harness connector.
Ignition on, engine not running.
Using a 12-volt test light, jumper across the EVAP Purge Solenoid harness connector.
With the DRBIII®, actuate the EVAP Purge Solenoid.
Does the test light flash on and off?
  1. Yes --> Replace the EVAP Purge Solenoid.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 3
3 Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the PCM harness connectors.
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 (K52) Evap Purge Solenoid Control circuit from the Evap Purge Solenoid harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 4
  2. No --> Repair the open in the (K52) Evap Purge Sol Control circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
4 Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the PCM harness connectors.
Measure the resistance between ground and the (K52) Evap Purge Sol Control circuit at the Evap Purge Solenoid harness connector.
Is the resistance below 5.0 ohms?
  1. Yes --> Repair the short to ground in the (K52) Evap Purge Solenoid Control circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 5
5 Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the PCM harness connectors.
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 (K108) Evap Purge Sol Return circuit from the Evap Purge Solenoid harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 6
  2. No --> Repair the open in the (K108) Evap Purge Sol Return circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
6 Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the PCM harness connectors.
Measure the resistance between ground and the (K108) Evap Purge Sol Return circuit at the Evap Purge Solenoid harness connector.
Is the resistance below 5.0 ohms?
  1. Yes --> Repair the short to ground in the (K108) Evap Purge Solenoid Return circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 7
7
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.Repair:Replace and program the Powertrain Control Module in accordance with the Service Information.Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
