Morning fellas, I've read through all the posts on power steering on here and although they have been helpful they haven't fixed or really diagnosed my issue.
The problem started a while back when doing a U turn and using full right hand lock the steering light came on. From then on the power steering became intermittent, then would only work at speeds above parking speeds and finally about a week ago it packed up altogether.
The code I get on obd11 is 00816 which equates to steering angle sensor.
Before doing anything I ran live data and although the pump had voltage and was showing rpm the angle didn't change when the steering wheel was moved. The original coding for the module was 10121.
I changed the coding to 11211 assuming my car has the G85 as it has cornering lights. The power steering didn't work but the CEL went off. Live data shows different values when the steering wheel is turned and different pump voltage/rpm during steering.
I then tried 10111 for the g250 sensor and this just put me back to square one. No live data other than consistent pump voltage and rpm.
The fact that the power steering has now completely failed would make me believe it was the pump but the pump showing a voltage and rpm and then fluctuations to the values when on the 11211 code would say the pump was working. Could it in fact be the g250 and that my pump isnt compatible with the g85? Would a sensor cause complete failure of the power steering?
As I mentioned above I have obd11 so if there's anything else I can look into please let me know.
Thanks so much for reading, any help is greatly appreciated. Regards John
