Hello I’m just wondering if anyone can share a reasonable place to purchase both front abs sensors. My vehicle abs codes 2-3 abs pressure switch, 2-12 front right sensor air gap, 2-14 front left sensor air gap. As a result I have no power brakes. I checked continuity and they are both closed loops. Spun the wheel checked volts and both fluctuating as the wheel spins?

Sensor gap too wide suggests they are not pushed down far enough. Did you take them out or do other work on the front axle? On the P 38 you push them down as far as possible, even tapping slightly to get them down. When you drive away the correct gap is set by the reluctor ring. Seems a bit odd to me that an ABS fault would prevent the brake booster from working.

I did tap them down today the vehicle is new to me but evidence shows recent work on front axle both sides. I have been driving it with manual brakes and hit a bump and all warning lights extinguished and power brakes worked but it was short lived.

I would deal with the abs pressure switch first to see if that would solve your soft brake issues.
do you hear the brake pump running?

If hitting a bump fixed the problem temporarily you must have a bad connection somewhere, maybe one of the ABS sensors or the fuse box.
