    Hello beautiful people and community:
    I have a 2013 Prius 5 with 200k miles. I bought this car with all the lights on the dash lit up like xmas tree. I had to replace the steering rack as soon as I bought the car, as it wouldn't drive straight. I have C1464 code for my front right ABS sensor. I verified on techstream that it is reading 0mph. I replaced the ABS sensor, still didn't fix it. I replaced the wheel bearing (thinking maybe tone ring issues) and still didn't fix it. I unplugged the connector from the ABS module, and verified that the wire is in good condition, and both front ABS sensors reading around 1.2-1.9 megaohms.

    I really don't know what else to replace. I know these cars have issues with ABS, but not exactly the module going bad. Of the more than 4 dozen cars i've had in my life, this is the first time I'm suspecting an ABS module just going bad, and not reading ABS sensor anymore.

    Is there anything else I can test here before just buying another ABS module and pump assembly? What is the best source for those things?

    Thank You, and be safe out there

    The ABS modules two of them go out on this car all the time you can read hundreds of posts about just that .

    If the only code you have is C1464 for a specific wheel sensor signal, have you followed the full troubleshooting procedure in the repair manual for that code?

    There are probably more answers besides "replace the sensor" or "it has to be the ECU".

    There's a PDF of the 2010 manual floating around but doesn't have that code in it. It may be a code added in a later model year. Might have to go on TIS to read about it.

    is that just the gen 2, or gen3 also has same issue?

    I don't have the full repair manual, so... but really there isn't too much involved. I just find it crazy it would be the ABS module

    Try replacing the pigtail even if it reads good, the terminal could be bad itself.
