3
Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the Powertrain Control Module harness connectors.
Measure the resistance of the (K52) Evap Purge Solenoid Control circuit from the
PCM harness connector to the Evap Purge Solenoid harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the open in the (K52) Evap Purge Solenoid Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
4
Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.

harness connector to the Evap Purge Solenoid harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 6
No
→ Repair the open in the (K70) Evap Purge Solenoid Sense circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
6
Turn the ignition off.
Disconnect the Evap Purge Solenoid harness connector.
Disconnect the Powertrain Control Module harness connectors.
Measure the resistance between ground and the (K70) Evap Purge Solenoid Sense
circuit at the Evap Purge Solenoid harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the short to ground in the (K70) Evap Purge Solenoid
Sense circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 7

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.
