ABS light with codes

noticed ABS light on after quick stop for red light, pulled hard to right, had codes scanned, C1155 LF speed sensor curcuit fault and C1158 LF coherency fault,
Stopped all three sensors read 3 mph, when you move right front and rear sensors read speed left front stays at 3 mph.
Need to know what next step might be. Sensor looks a long way inside there.
Removed, lubed and reinstalled brakes last fall, good thing pins were just about seized into caliper mount, but didn't get in as far as ABS sensor.
Any help appreciated.

Thanks

your sensor is bad dude, make sure the wheel bearing is tight as they have been known to get sloppy and take out the sensor tip on 99-ups

unfortunatly you have to pull the rotor, but just remove the allen bolt and give it a slight twist to break the o-ring seal then it will just lift out, maybee need a very small screwdriver to pry gently up

If I take my time I can make this a weekend project, ignore the honey do list again an repaint my oil pan while I'm half way under the truck anyway, noticed a little paint peeling off when I done oil change week ago. Rust on the oil pan should not be left unattended for very long.
