Monitor Description

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

The hybrid vehicle control ECU calculates the differences of the voltage of main accelerator sensor and sub accelerator sensor. If the differences exceed prescribed values, the hybrid vehicle control ECU determines that there is a malfunction in the accelerator sensor circuit. If the hybrid vehicle control ECU detects this malfunction, it will illuminate the MIL and store a DTC.
