Somebody took the wheel off to check the clock spring and turned the steering angle sensor more than 850 degrees so it is now stuck at 850. I have seen some people remove that code from dump and steering sensor worked after that fine. There is no problem with the sensor.
Thank you,

You can try to remove the 4 bytes after "aa 55" in line 80

Thanx, after writing back I scan it has a same code, and still have 850 degrees stuck.

Any other Ideas?
Thank you

My last guess would be to also clear out the data in line A0 after the 2 bytes "aa 5a"

Sorry I can't be more helpful,

Good luck!

Please do.

Or just use original dump and set the angle sensor closer to zero while cheking it on diagnostics

With original dump it is always showing 850.5 degrees. Even when it is straight at 0 degrees. Toyota sensors have a specific range, if exceeded that range the sensor writes error code inside eeprom and stops working. When the sensor is connected in the car and somebody is checking if the clockspring is good, they go over the range with a good clockspring killing the sensor.

Is it possible that the steering angle sensor physically broke, like how a clock spring can break by over turning? I have never taken a steering angle sensor apart on a Toyota before

Hi, Clockspring max turn on toyota usually around 900 degrees one way.
Steering angle sensor max turn is less than 850 degrees. that is where the problem starts.

I fixed some before but older ones, none with 93c66 so far.
I don't have a clue on this one.. what year is this prius?
