Avenger V6-2.7L (2008)
The Output Speed Sensor (1) provides information on how fast the output shaft is rotating. As the rear planetary carrier park pawl lugs pass by the sensor
coil, an AC voltage is generated and sent to the PCM/TCM. The PCM/TCM interprets this information as output shaft rpm.
The PCM/TCM compares the input and output speed signals to determine the following:
-
Transmission gear ratio
-
Speed ratio error detection
-
CVI calculation
VEHICLE SPEED SIGNAL
The vehicle speed signal is taken from the Output Speed Sensor. The PCM converts this signal into a pulse per mile signal and sends the vehicle speed
message across the communication bus to the BCM. The BCM sends this signal to the Instrument Cluster to display vehicle speed to the driver. The
vehicle speed signal pulse is roughly 8000 pulses per mile.
