Chrysler Cirrus Problem Report
Chrysler Cirrus The Cruise Control and Speedometer May Fail Due to Speed Sensor Issues
Defective speed sensors on the transmission can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors can corrode and/or the connector terminals can spread (poor connection), which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.
