Pinpoint Test I : The Analog Temperature Gauge Is Inoperative: Notes

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions 

See Temperature Gauge. Refer to Instrument Panel Cluster (IPC) .

NOTE: If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative tachometer, speedometer or odometer.

If the IPC does not receive the engine coolant temperature and engine overheat mitigation active message from the PCM for longer than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the temperature gauge to cold (C). If the engine coolant temperature message is deemed invalid by the IPC for 5 seconds or more, the IPC defaults the temperature gauge to cold (C).
