I recently replaced the front brake pads and rotors on my 2009 Lexus ES350. Car was working fine until I started taking some right hand turns at speed. ABS would kick on very easily (w/out wheel slippage) and pulse the front left wheel. Traction light would come on then go away after about 5 seconds. I read a ton of reviews on these types of sites and narrowed it down to the ABS wheel sensor, the wheel bearing, sticking caliper, or possibly the steering wheel angle sensor. I replaced the ABS sensor and the problem did not go away. I could not re-calibrate the angle sensor with my crappy little OBD2 tool so I finally gave in and took it to a local shop. Turns out it was the steering wheel angle sensor had somehow re-calibrated 3 degrees off. They re-calibrated the steering wheel angle sensor and the car is now back to normal.

I'm pretty familiar with cars and I just wanted to share if anyone else runs into this issue where the ABS is kicking for no apparent reason while making hard turns.

I bet it's the speed sensor
