Circuit description

WARNING: This page is about a different variant/trim than selected.

The oil temperature sensor installed in the valve body detects the oil temperature in the transmission hydraulic control circuit and inputs signals corresponding to the oil temperature to the transmission control computer ASSY.

NOTE:
  • The data monitor (AT oil temperature) indicates -40°C when P0712 is output.
  • The data monitor (AT oil temperature) indicates 171°C when P0713 is output.
