Monitor Description

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

The ECM IAC1 terminal voltage increases in correlation with the opening angle of the tumble control valve. When the tumble control valve is fully closed, approximately 0.8 V is applied to the IAC1 terminal. When the tumble control valve is fully open, approximately 3.6 V is applied to the IAC1 terminal. When the output voltage of the IAC1 terminal deviates from the standard range, the ECM determines that a malfunction has occurred in the position sensor and stores a DTC. Refer to ECM POWER SOURCE CIRCUIT .
