B1334 SATURN Description
The right air temperature switch assembly is a sliding potentiometer with detents that correspond to fixed resistance values. The Instrument Panel Integration Module (IPM) supplies 5 volts to the right air temperature switch signal circuit and provides a low reference circuit. The IPM determines which switch position has been selected by the voltage drop across the corresponding resistance value. The OBDII code sets when the IPM detects that the right air temperature switch signal circuit is less than 0.09 volts (5 counts) or greater than 4.90 volts (250 counts).
