I had never had this come up before, and I did some reading on the forum to figure out what it could be. I know there are two, but I'm not sure which is 1 or 2. I cleared the code and will drive again to see if it comes up. However, if it does, which is which, and what are the chances that I really have the issue and that this just picked up something else? I hope it is nothing but time will tell. I have not felt any change in performance, and it still runs great. Could it be bad gas? Could it be a wire came loose after 191K? Could it be something that is going to be disastrous?

 

The knock sensors are labeled as A and B on the wiring guide so that doesn't help

The A is probably the # 1 probably the fwd one

You might remove the fwd connector and see a CEL code that correlates to the position of your first code

You can swap sensors before purchasing another one

Someone did ask before if there will be a oil spill that I can't recall or think through.

 

You said diagram. From where. I went ahead and cleared it and drove 5 miles and it stayed clear. Driving to play golf about 20 miles away. Will see if it stays cleared. Fingers xrossed

 

Page 50 of the 97 wiring guide

labeled as KS

There may be something in the Jaguar 801s pdf

Page 87 and 99 as a interesting second paragraph with the CKPS seeing a misfire vs. a predetonation knock

See page 125 as CEL code P0326 identifies Knock Sensing Circuit 1 as cylinder 1 , 2 , 3 or fwd position of the 2 KS sensors

Burn off your tank of fuel and see if it accurse with fresh fuel

Using regular unleaded fuel with lower octane number ? On aircraft piston engines if using automotive fuel we would have to by federal order retard the ignition timing by around 5 degrees Vs.higher octane aviation fuel original engine design

Good old World War 2 aviation fuel was 145 but todays aviation fuel is 115 octane

I rejected a aircraft once while taking flying lesson as it was way underperforming on a end of runway performance check comparing the aircraft's 2 ignition systems , yes they have 2 including 2 spark plugs per cylender

This is what a properly running Britch engine should sound like ,you gotta hook this up to your good stereo or good headphones
