Ignition/Distributor Engine Speed Input Circuit
A general electrical fault is reported on the engine speed input from the ignition/distributor — open, shorted, or out of plausibility. On older systems this is the distributor pickup; on newer ones it is the crank/cam-derived speed signal feeding the ignition driver.
