Pinpoint Test L : The Analog Transmission Temperature Gauge Is Inoperative: Notes
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
See Transmission Temperature Gauge. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the IPC does not receive the transmission temperature data message or if the engine coolant temperature message is deemed invalid from the PCM for 5 seconds or longer, the IPC defaults the transmission temperature gauge to cold (C).
