DIAGNOSIS PROCEDURE - P0443-EVAP PURGE SOLENOID CIRCUIT
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Start by reading PCM DTC(s) and record the related Freeze Frame data in any DTC(s) are present. Check the vehicle repair history. If the vehicle has a repair history that pertains to the customer's current complaint, review the repair. Inspect the vehicle for any aftermarket accessories that may have been installed incorrectly. Check for any service bulletin(s) related to the customer's complaint or DTC(s). If a service bulletin applies, follow the instructions per service bulletin. Did the service bulletin repair the customer's complaint? Yes --> Testing Complete. Perform POWERTRAIN VERIFICATION TEST VER - 5 . No --> Go To 2 |
All |
| 2 | Ignition on, engine not running. With the DRBIII®, read DTCs. Is the Good Trip Counter displayed and equal to zero? Yes --> Go To 3 No --> Refer to the INTERMITTENT CONDITION . Perform POWERTRAIN VERIFICATION TEST VER - 5 . |
All |
| 3 | Turn the ignition off. Disconnect the EVAP Purge Solenoid harness connector. Ignition on, engine not running. Using a 12-volt test light, jump across the Evap Purge Sol Control circuit and Evap Purge Sol Signal circuits in the EVAP Purge Solenoid harness connector. With the DRBIII®, actuate the EVAP Purge Solenoid. Does the test light flash on and off? Yes --> Replace the EVAP Purge Solenoid. Perform POWERTRAIN VERIFICATION TEST VER - 5 . No --> Go To 4 |
All |
| 4 | Turn the ignition off. 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 Evap Purge Sol Control circuit from the Evap Purge Solenoid harness connector to the appropriate terminal of special tool #8815. Is the resistance below 5.0 ohms? Yes --> Go To 5 No --> Repair the open in the Evap Purge Sol Control circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5 . |
All |
| 5 | Measure the resistance between ground and the Evap Purge Sol Control circuit at the Evap Purge Solenoid harness connector. Is the resistance below 5.0 ohms? Yes --> Repair the short to ground in the Evap Purge Sol Control circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5 . No --> Go To 6 |
All |
| 6 | Measure the resistance of the Evap Purge Sol Signal circuit from the Evap Purge Solenoid harness connector to the appropriate terminal of special tool #8815. Is the resistance below 5.0 ohms? Yes --> Go To 7 No --> Repair the open in the Evap Purge Sol Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5 . |
All |
| 7 | Measure the resistance between ground and the Evap Purge Sol Signal circuit at the Evap Purge Solenoid harness connector. Is the resistance below 5.0 ohms? Yes --> Repair the short to ground in the Evap Purge Sol Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 5 . No --> Go To 8 |
All |
| 8 |
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.If there are no possible causes remaining, view repair.RepairReplace and program the Powertrain Control Module per Service Information.Perform POWERTRAIN VERIFICATION TEST VER - 5 . |
