2004 Explorer XLt Code C1233, C1223, C1440 ABS issue

[dionysius1]

Hi everyone. I am new to this and not much of a mechanic, but trying to do my own work. My ABS light came on and the 4x4 light flashes. When making turns slowly, the whole gearbox seams to get tight and almost seize. The codes that came up are C1233, C1234, and C1440.

Based on that, I changed the ABS sensors for both front wheels. It didn't help. Light is still on and the other issue still exists. Any clue what I should be looking for? Any help is appreciate

This thread refers to the C1440 code:

Sounds like the brake pressure transducer is causing the
C1440 code. Once you resolve the C1440, the other codes
may disappear...

Not resolved

Thanks for the advice. Replacing it took care of the C1440 code, but all of the other problems are still there. Cant figure out why both front sensors are out and the gear box is locking at slow speeds...guess it is time for a pro to look at it
