Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM (for Gasoline Model): Engine Oil Pressure Switch Circuit; 2019 - 2022 MY Avalon [04/2018 -        ]

Engine Oil Pressure Switch Circuit

DESCRIPTION

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

HINT:

  • The combination meter assembly receives engine RPM data signal from the ECM via CAN communication in order to output warnings.
  • The combination meter assembly operates the following to output oil pressure warnings:
    1. Engine oil pressure warning buzzer
    2. Engine oil pressure warning message on multi-information display
