Note On Intermittents

If Code B113 is set with Code B115, check for an intermittent open in circuit No. 736 between splice "S2" and Instrument Panel (IP)-to-dash transition block. If an intermittent Code B113 is being set, manipulate related wiring while observing BD25 display. If failure is induced, reading will jump from its normal value to a reading outside the range of -29°F (-34°C) to 209°F (85°C).

If value indicated by BD25 display is not reasonably close to actual temperature of air at sensor, check for poor terminal contact or replace sensor.
