Fluid Temperature Sensor
WARNING: This page is about a different car, the 2012 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
If an unexpected signal is sent from the fluid temperature sensor to the TCM, the gear ratio obtained immediately before receiving the unexpected signal is maintained and the gear ratio is controlled to keep engine speed under 5, 000 RPM (approximately), depending on driving conditions.
