Hi,

Not 100% sure what it will do but I imagine to drive a car without one would be awful Jerking/stutter, over fueling, sluggish in hardly any power at times. I could be wrong but thats what I would think would happen.

I asked because on polish subaru forum many people has issues with power and when they change position knock sensor for example move near gearbox, issue disappear. Knock sensor it's to sensitive.

If disconnect it will run on fault mode & safety map.

Don't just assume it too sensitive, many people using poor fuel (turbo model even more so) are possibly experiencing some det. I would check for det with independent det meter & also check condition, resistance/voltage of current sensor along with fault code reading & test drive with data logging plus wideband for fuelling check & replace or consider repositioning pending on what results I got from inspections/tests.

Point being I have replaced a few bad ones on older Subarus & come across the odd bad/damaged connector but never needed reposition one. A good knock sensor can be had for around 18 to £25 from good autofactors or even eBay these days .
