thanks,

RB20/25/26 knock sensors are all the same.

I'm after a pair also. :S

How are yours playing up? My original set wouldn't read any higher than 1 knock on the pfc.

This other set I have in won't read higher than ~14.

I've put the multimeter on to them and they have gone open circuit? i think. Constantly reading 13-14volts.

one was completely melted & the other got lost during a year long rebuild. I thought the best way to test them is to tap the block lightly with a hammer and u should be able to hear the timing retard.

If you have the engine manual you can get a rough idea if they are working as there's a small test you can perform with a multimeter.

Tapping the block may not work as the knock sensors only hear between 2 frequency's.

Apart from that.. You have a powerfc with a knock readout. Let us know if the block tap works.

Just found out through a guy who imports the sensors new that rb20/25 sensors are heaps defferent from rb26. the 20/25 ones come straight out with round green plug on the end and the 26 ones are round with a bolt through the middle and a square 2 pin plug coming off at 45 degrees. I think the 26 ones are the same as sr20.

If your after the 20/25 ones i know someone with a couple on a dead motor.

I'll thank a couple of different wreckers for that incorrect information.

Cheers for the heads up.

How much can you get the new sensors for? I know the sensors you are talking of as I've seen them on a lot of the newer nissans and sr20dets.

The 90's maxima's run them also. BMW's almost everything.

So I have 4 knock sensors to suit an rb20/25. :S

I can get the RB26 ones through nissan trade at $300 and aftermarket for 250. Rang nissan and they reckon the part no's for sr20 ones is different to rb26 but i found some sr ones at a wrecker for 45 ea and they look identical. gonna put them in and get this thing running at last. yeah maxima's also run them as well as a few other nissans i cant think of right now.
