Question
1998 Volvo S70.  Knock Sensor code popping up.  Can you tell me where to find it - can I replace myself.  ABS / Tracs Off light comes on same time - is this related. When turning the wheel all the way, clicking noise occurs.  Can you give me any ideas on what to look at?

Answer
The knock sensor is located on the front of the block under the intake manifold. There are 2. Easy to do, but they don't go bad very often so be sure to ferify that is the cause of the code.  The ABS light is almost certainly a failed ABS module and is not related to the knock sensor codes.  The clicking noise is either a steering rack, column or something stuck in the column rubbing.  I can't say which for sure without hearing the noise for myself.  If you can't hear a problem directly from the column expect a steering rack.
