What am I missing-ABS Deceleration Sensor??

Sounds important! What does it do?

ABS Unit sends a.signal to Engine module during decel (there is a mercury switch in this sensor to determine decel) engine module opens up idle air motor to reduce engine braking and thereby reduce chance of an engine braking induced skid (which on an AWD IX would be all four wheels,and dangerous)

That's the decel sensor for ABS
