Knock Sensor 2
« on: 28 August 2006, 19:03:55 »
Project TB1 keeps lighting up EML with Knock Sensor Circuit 2.

I think I need to renew the plenum O rings as they look tired, and there does seem to be a sucking noise from under plenum.

Could this possible air leak cause the knock sensor error? Or should I be replacing knock sensor? Can they be swapped side to side (see if fault moves with sensor or stays on same bank)?

Any pointers on what else can cause this problem would be appreciated....

I also reckon the car is holding back a little, esp under load...  ...related? Could be, as normally when eml comes on...

Is the part number the same for the two?? Different part numbers would suggest a difference.

Did you change the petrol filter?

I haven't changed fuel filter - wouldn't have thought that would cause knock sensor probs? Might affect performance though...

I think the holding back may be related to knock sensor (this would retard ignition I guess?).... ...I'd be surprised if the fuel filter would make that much difference (this car does seem quite sluggish).

My MV6 one was fairly dirty (thanks dealer, for charging me for replacing, and not  >:(), but difference wasn't really noticable.

I believe the knock sensors are piezo ceramic, so they're likely to give a problem if cracked (physically damaged) or loose. Otherwise there's not much else to go wrong except wiring.

I'd check it's on tight first.

I wouldn't expect an air leak to fool them.
