Overview:This code indicates an electrical problem in the output shaft speed sensor circuit. The signal from the sensor did not match the current operating conditions. Detection:A Speed Sensor is determined faulty when all Speed Sensor readings are compared and one sensor is inconsistent. Fallback:This fault causes a 5-speed fallback and the transmission stays in either LO range or HI range. When the vehicle comes to a stop, an attempt to shift into LO range is made. The fallback causes a 1-speed fallback on transmissions with no auxiliary section.

Overview:This code indicates an electrical failure of the rail select motor that drives the electric shifter. Detection:Starting at key-on and throughout operation, the Transmission Controller constantly measures the motor circuit. Failure mode of short to battery, short to ground, or open circuit is detected. The Transmission Controller also monitors the amount of current required to drive the motors. If the over current limit is exceeded, the fault code is also set. Fallback:This fault causes an In Place fallback.
