Circuit Description

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

TP sensor No. 1 signal is fed into a multiplexer (5X) to produce a high resolution calculated TP sensor voltage. This higher resolution TP sensor voltage is used for actuator control in low throttle angle conditions.

DTC will set when high resolution TP sensor is out of range for one second.
