P0443-EVAP PURGE SOLENOID CIRCUIT —
TEST
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 TERMI-
NALS 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?
Yes → Go To 4
→ Repair the open in the (K52) Evap Purge Sol Control circuit.
No
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?
Yes → Repair the short to ground in the (K52) Evap Purge Solenoid
→ Go To 5
No
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 TERMI-
NALS 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?
Yes → Go To 6
→ Repair the open in the (K108) Evap Purge Sol Return circuit.
No
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?
Yes → Repair the short to ground in the (K108) Evap Purge Solenoid
→ Go To 7
No
