Hello, my 2002 C32 steering is much lighter now and the steering jerks back about 2 inches every time I steer in any direction at any speed. The shop said (after the install of control arms and tie rods and an alignment) I have a sensor issue although it worked fine earlier in the day. Running codes, the guy said I have C1352,1212,1174,1173,1172, and 1170. (Rotation speed/lateral accelerator sensor, Over/Under voltage terminal 30/ and steering angle sensor for the others respectively) The first few may have been cleared with turning the wheel lock to lock to rest. But the jerking remains. The car is still drive-able somewhat but this is a serious issue. Could there be another reset or something that needs to be done? I am considering getting a junkyard steering angle sensor this weekend but would like 2nd opinions. Prior to this I had no issues at all with steering, although fairly heavy steering (which I believe to be standard?) Thank you so much for any help you can offer.
