Fuel System: Notes

WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

The fuel system is controlled by PCM. The PCM monitors engine operating conditions based on input received from engine switches and sensors. Control of output actuators determines fuel mixture and idle speed.
