AOA, I own a Prius 2011, 1.8. few days back horn stops blowing when car steering is in center position. When steering is deflected left/right, horn works fine. Mechanic checked spiral cable and found it to be faulty. When he put spiral cable back to its place and closed the steering assembly, traction light came on. He said that it is because calibration of angle sensor has been disturbed which can be recalibrated. Today I went to him to get it recalibrated but he said angle sensor has gone faulty and needs replacement. Now I need expert opinion. Is it like that? Does traction light on means angle sensor is faulty? Is there any other solution other than replacement? Thanx
