Monitor Strategy Description

The throttle position is determined by a two-channeled sensor. Both channels deliver inverse dispersing voltage signals. In order to reduce the measurement inaccuracy, the two signal voltages will be referenced to their supply voltage. After the initial engine start and component change the sensor characteristic is learnt within an adaptation routine. The learned values for the limp-home position, the lower mechanical stop and the TPS 1 amplification are stored at the end of the driving cycle as "non-volatile".
