Is this recommended on the AP2? And should a genuine new OEM Honda knock sensor be used?

Thanks!

 

There is never a reason to change the knock sensor, unless you physically break it while accessing the upper starter bolt.

 

agree. Really no reason unless you break it. And if you do break I think OEM is the best bet. I have seen some complain of issues with aftermarket ones.

I had to replace mine, not because of the starter bolt, but because I had to replace the o-ring on the water outlet on the block, which besides a lot of cussing, involves cramming your hand behind, around and under the intake manifold, and during working on that managed to push my hand into the knock sensor and break it.

 

So, the car periodically not starting, with a good battery, alternator, and connections is probably a starter issue. Several YouTube videos suggest knock sensors cause periodic non-starts in Hondas (not necessarily S2000s).

Thanks for the quick reply!

 

Filthy filthy knock sensor. Thanks for the PTSD.

 

Most will break a knock sensor removing the starter or upper starter bolt.

 

Its amazing what people make up about cars.

A broken or bad knock sensor has nothing to do with the car’s ability to start.

 

Well, Youtube says it does smart guy. What, you a mechanic or sumthin"?

 

Every now and then, couple of times a year really, I will get the starter to drag a bit making the gear stay engaged and "grind" on disconnect. Someday I will get off my can and clean the starter out. I suppose I should get a knock sensor in anticipation of breaking it like so many have testified.

 

Unplug the knock sensor first, from underneath. It will reveal its bright green color. Then you can keep eyes on it while accessing the upper starter bolt.
