Question

I need ti replace the knock sensor 1 on my 2001 Subaru Outback 2.5 litre engine. Where is it located and are there any special considerations with this replacement?

Answer 1

The knock sensor is bolted to the engine block, just under the throttle cables on the driver side of the engine. One 12 mm bolt holds it there.
