The two speed sensors in the transmission system and use a common ground circuit. The loss of this common ground results in the input signal being sensed by both sensors. After a reset and in neutral, and observing a certain Output/Input ratio will increment the Speed Check Fault Counter. Because the speed sensors and the thermistor share the same ground wire, this DTC may indicate a loss of the common speed sensor ground. In some cases this fault will cause a Gear Ratio Error DTC to be set.
