I have codes C1235 and C1464 that pop up. I can clear them, but then they come back because the sensor seems to spike speed. On live data, it is still reading, but it kicks the code. The axle was pretty rusty where the sensor would read so I replaced it while doing pads/rotors. The oem sensor is about 250$ so I sourced one off of amazon. It took a couple tries to get the correct one, the plug was the same, but the tip was longer. It still seems to do the same thing with the new sensor. I have replaced a ton of the sensors on them, but usually the rear and they are less than 40$ from the dealer. Is there a reason why the RF seems to be so much more expensive and does anyone have any other ideas on a fix. Thanks for any information.
Update. Fixed the problem. It was the inside of the wheel bearing. The magnetic ring had basically disintegrated. I should have looked at it first I guess.
