The signals generated from the EGR valve are 5 volt digital signals that reflect one of three positions of the rotor of the brushless DC motor. These are typically called hall effect outputs. The transitions on channel B occur about 1/3 of the pulse width after the transition of channel A. Channel C transitions happens about 2/3 of the way ... The EGR system module (ESM) is one of Ford's latest EGR system for gasoline engines. It is an EGR valve, EVR, MAP and DPFE sensor rolled into one package. Though the DPFE sensor on an ESM is referred to as "DPFE" by the scan tool and also wiring diagrams, it is not a traditional DPFE sensor as used on the older EGR system. It is actually two separate MAP sensors. I've determined that the valve has two 21 ohm coils. I expose these coils (together, or separately) to 12VDC but the valve does not open.
