WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the vacuum hose (black, black with red paint mark) from the evaporative emission (EVAP) purge solenoid.NOTE: When disconnecting the vacuum hose, always place an identification mark so that it can be reconnected at its original position.
- Disconnect the harness connector.
- Connect a hand vacuum pump to nipple (A) of the EVAP purge solenoid (refer to the illustration).
- As described in the JUMPER WIRE SPECIFICATION
