    I have Prius 2010. Now facing the same P Lock error for the past few weeks. After reading all the above threads, i also replaced my battery but that evil P error is still there. Even the replaced battery is perfectly fine. I have also get it checked quite a few times but that P error is now getting on my nerves.
    I have also tried to remove the 7.5 fuse from the switch box but P error is still there.
    Whenever P error appears, I simply apply the parking brake and turn the vehicle off. After 5 minutes wait, i turn it on the vehicle and every back to normal like nothing would had happened.
    Please help me out. May i need to replace that 7.5 fuse or connect some cable between the 7.5 fuse to blue wire. Or what.
    If anyone know the permanent solution of this problem, please do let me know
    Let me reiterate that 12V battery is perfectly fine.
    Please HELP.
