Brake Job gone Awry
Hello,
Not a good night. I replaced my right front wheel hub (and wheel speed sensor) and my pads and rotors. I am now getting:
1) ABS Code C0200 - ABS Current Right Front Wheel Speed Sensor Signal Malfunction.
2) ABS Code C1223 - ABS Current Malfunction in ABS Control System
3) Spongy brakes and a whooshing sound when I hit the pedal at a stop.
4) Vibration during braking at highway speeds.
WTF?? Are these all related? Did I do something wrong? I followed the procedure in the manual and pulled the calipers towards the outside of the vehicle when installing.
I just replaced the damn sensor and now it's giving me the same error - maybe it's the cable? For the spongy brakes is all I need a bleed (I didn't disconnect any lines)?
I need a cold one.

After new pads and rotors in the front you should have no vibration at braking... assuming you bedded the brakes in correctly. And yes, for the spongy brakes, definitely a bleed is needed. I know it's frustrating to do all that work and not have it come out right. And yes, since you touched the brakes/sensors/wires then these codes are probably related to that recent work...unfortunately.

I had a C0200 error or "CHECK VSC" warning light for the right front speed sensor on for the better part of the year and I finally got around to changing the sensor this weekend. I am still getting that light with an additional C1223 code. Maybe it's the cable?
Will have to check that tomorrow. I think I'm done for the evening

Man that really sucks. Good for you, doing this by yourself though.
I just have one quick question - did you clear the codes when you fixed your car?
Just asking because - your car had the code, but if you fix the problem without resetting the code, the car will continue to show the code. It's not sophisticated enough to say, 'well I have a good signal now, I'll turn off the light'
I don't know whether you have access to OBD readers, but most of them can clear codes. Usually car stores and car tool stores will have them for not a lot of money. I got mine off amazon for $25 or so.
It might be time to take this car to a Toyota specialist, though. The electronic controls on ABS get to be pretty tricky, and they've probably seen these issues before.

I'd take it apart and make sure everything was installed correctly. Make sure it matches exactly against the other side. Maybe swap sensor from side to side if they are if they are universal. If you take it apart and check everything and still have a fault, I'd take it to Lexus or Toyota and have the brakes checked out before I drove it any further.

Braking vibration may be caused by rotor "runout". Brake rotors may not be seated flush on hub, or hub not seated flush on steering knuckle. With all that rust you had, did you clean that knuckle out so the new hub seats flush when bolted in? If you did not replace the rotors, the back of the old rotor may also have rust build-up preventing flush seating on the wheel hub.

The LS430 pads, if I remember correctly from my previous change, are not directional in any way, so you can install them whichever way (pad facing rotor of course). So, you won't mess them up by putting them in wrong or seating them incorrectly. The slot that the pads it in, it's going to set properly.
1) ABS Code C0200 - ABS Current Right Front Wheel Speed Sensor Signal Malfunction.
2) ABS Code C1223 - ABS Current Malfunction in ABS Control System
I would say either bad sensors, or you need to remove and sets the connectors to get a better contact.
3) Spongy brakes and a whooshing sound when I hit the pedal at a stop.
Bleed the brakes, but if you didn't have issue before repair, then be on lookout for brake fluid because air got in somehow, somewhere.
4) Vibration during braking at highway speeds.
Perhaps a slightly warped rotor that just gets worse at highway speeds as the rotors heat up during braking. I'd have it looked and see if resurfacing is needed.

I took the car to the shop today. They told me that the brakes were fine and that the rotors are within spec and that the runout is also within spec.
As the rotors wear in more the vibration has gradually faded and the pedal seems to have stiffened up. These rotors were plated with a zinc coating to prevent rusting and I'm wondering whether this initial surface was causing this.
For the wheel hub sensor, the shop told me that they checked the cable and it is good. The problem points to the new sensor. I don't know what the chances are that a new factory OEM (from Sewell) hub and wheel speed sensor assembly can be bad, I guess I won't be buying any lottery tickets any time soon.
I guess the next step is to try and swap it with the sensor on the other side to see if the error code changes to the front left.
I am not looking forward to pulling that sucker out. Looks like it will be press time again!

I may visit the Toyota / Lexus specialist if I absolutely have to, but they scare me. Most of the dealerships around where I live have a bad reputation of shafting the customer.
