How to Test the PCM on a Ford

Dodge PCM

A Ford's Powertrain Control Module (PCM) works like the central computer for diagnostic system of the vehicle it is used on. The PCM scrutinizes both, the sensor readings as well as the way engine functions. When a component within the engine or fueling system begins to conk or malfunctions, the PCM immediately issues a code which leads to appearance of the problem label. If the PCM stops working, your Ford's diagnostic system will render unreliable. You can test PCM device within a few minutes.

Before you throw money on testing the PCM on a Ford, or take risks with such an important component, read this post. It should hopefully provide you with some helpful practical tips as you reach out to a technician who can help you test it.
