3. Step-by-Step DIY Repair Guide for Chrysler Pacifica Hybrid
Find the purge valve mounted on the intake manifold with one vacuum line leading to the intake and one to the charcoal canister. on the Chrysler Pacifica Hybrid equipped with 3.6L Atkinson-Cycle V6 + Dual Electric Motors (260 HP PHEV / 32-Mile EV).
Unplug 2-pin connector and measure resistance across terminals with multimeter. Typical spec is 14–30 ohms. If open (OL) or shorted (0 ohms), solenoid is dead. on the Chrysler Pacifica Hybrid equipped with 3.6L Atkinson-Cycle V6 + Dual Electric Motors (260 HP PHEV / 32-Mile EV).
