Hello All!


Last weekend, my girlfriend lost power steering in the BRZ and the warning light came on. She managed to get it home, but I am not comfortable with her driving the car without power steering, so she's currently driving my old truck.



The power steering failure is consistent in my limited testing after she got home and I drove it around the neighborhood. Sometimes, after turning the car off and back on, it will clear briefly and the power steering will work, but most times it just displays the failure as soon as the car is started. The car drives like a car with no power steering when the power steering turns off and it is now consistently turning off even directly on some cold starts.



I got out my handy OBDII reader, however the car is showing no logged codes or pending codes.



Obviously the first thing I did was search this forum for similar issues. I saw a number of threads on the issue. Tons of them don't have resolutions in the threads, others have suggested a few items:


1. Battery Failing under Load -- This was my first thought, as the battery in the car has been leaking gases since I got the car and I've been battling corrosion when I open the engine compartment. I took the battery to our local battery store yesterday, the load tested it, said it was failing under load. I got a new battery from them and installed it yesterday evening. A new battery did not resolve my issue.


2. Steering Angle Sensor -- Saw some posts about this from people who have taken their cars to the dealer, but most of them have reported that even after getting it replaced from the dealer, the failure continues.


3. Failed / Bad ECU -- This seems most likely. At a reported cost on the forums of about $1,500, I'm really hoping this isn't the issue, but this is what my head is telling me.



I really, really don't want to take it to the dealer, but I will if there are no further troubleshooting suggestions I can try at home that you guys might have. I just know if I do, it's going to be a big bill and I have enough of those right now.



I would love to try and resolve this on my own if there's anything else I can try other than code reading and the new battery, which I have already done. Let me know if anyone else has had this issue and has resolved it without taking it to the dealer, thanks!
