Welcome to this forum! Did you or your mechanic use an alignment tool on the sensors? Is the reluctor ring damaged?

Yes, the tool was used, and I'm not sure what the reluctor ring is but the sensor is brand new.

You have to find out if the sensors are providing a pulse as feedback to the PCM when the engine is turning. These sensors have a collapsing & expanding magnetic field just like ABS sensors. Your mechanic should be able to check the signal on an oscilloscope. Check this link for more information: http://www.dakotart.com/forum/showt...-Sensors-and-Reluctor-Ring-information-needed
