Can I use a 91+ knock sensor on my '87?

I remember reading somewhere this was possible if a certain type of coating was used on the pins, or is that nonsense?

 

they are all interchangable.

 

You could use a dielectric grease as theoretically there could be the possibility of corrosion. In practise, little possibility of that unless lots of water involved. I have the gold plated sockets in stock if you want to bother changing them.

 

I have the gold plated ones from Roger......very nice and cheaper than stock too

 

Yes I supply Roger as well.

 

I'm using the gold plated ones in my '89 GT with no issues. As others have said, much cheaper.

 

Well I can now confirm that using the older knock sensors in a new car with the gold-plated connectors on the harness side causes corrosion and connectivity problems pretty fast. I was getting an intermittent front knock sensor fault on the ST2 so I disconnected the front knock sensor connector and noticed that the sensor was changed with an older style and there was a bunch of gray corrosion gunk on both the connector end and the knock sensor end. I cleaned them both up, reconnected and fault no longer appears. I am not sure how long this sensor was in there, but it couldn't have been more than 5 or so years.

Thing is, if I didn't have the ST2 hooked up all the time, I probably wouldn't have noticed...

Now that we have that cleared up and on the subject of knock sensors.

Can I put a knock sensors on my 86 ?
What one ?
How would I conect it?
Is there a plug for it already ?
I would apprecite the help on this one.

Cheers
Matt

 

Porken has one installed.

Thanks Hilton that was very helpful !

 

Nearly two years on and no problems with the cheaper 91+ knock sensors.

 

Some dielectric grease when mixing contact types would help, to exclude the air.

 

So what's the actual difference between early and late knock sensors?

 

The later ones have gold-plated contacts and the earlier ones do not.

Thanks Dan.
