Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Engine Oil Level Sensor Circuit; 2018 - 2024 MY Camry HV [07/2017 -        ]

Engine Oil Level Sensor Circuit

DESCRIPTION

The combination meter assembly and engine oil level sensor are connected via direct line. The combination meter assembly determines the engine oil level based on the engine oil level sensor ON/OFF signal.

HINT:

As the engine oil level may be unstable when the engine is cold or running at high speeds, the combination meter assembly receives the engine coolant temperature signal and engine speed signal from the ECM via CAN communication in order to prevent the oil level warnings from being output erroneously.

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.
  • The following troubleshooting procedure is based on the assumption that the SFI system is normal. Confirm that the SFI system is not malfunctioning before performing the following procedure.
