Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Engine Coolant Temperature Receiver Gauge Malfunction; 2018 - 2024 MY Camry [06/2017 -        ]

Engine Coolant Temperature Receiver Gauge Malfunction

DESCRIPTION

In this circuit, the combination meter assembly receives engine coolant temperature signals from the ECM via CAN communication. The combination meter assembly displays an engine coolant temperature warning based on the data received from the ECM.

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
  • Before replacing the ECM, refer to Registration.

HINT:

If there is an open or short in the engine coolant temperature sensor circuit, the ECM stores DTCs. Troubleshoot the SFI system.
