Ok a little help if you can.
Went out on a drive yesterday with no issues did about 30 miles round trip. Got up this morning and decided to go on another drive out to Doncaster.
On way to fill up with gold liquid the engine management light flickered. Filled up and set off no problems. Half way there and eml was permanently flashing. The faster I went the more the light stayed on and when I slowed down it flashed more. It did this all the way to where I was goint.
Once there I checked all connections and the only thing I noticed was that the exhaust from manifold/downpipe sounded louder as if something may need tightening. Set off back and other than a little power loss at bottom end at set off there appeared no issues. Half way home on the A1 I would her up to overtake a few lorrys before joining m18 and light went off. This stayed off for around 10 miles then came back on when cruising at 30.
This then stayed on the rest of the way home. Ive done a paperclip test and come up with the following code::
12
16
31
Im wondering if these may have been caused by the exhaust coming loose or if it may be something else as like I say she drives great and definatly had no hestiation on the motorway :-?
-
Sorry to hear it's reared its ugly head again!
As for codes, 12 is start of sequence and 31 is no RPM signal. Did you have the engine running when you did the test?
Assuming not, 16 is all you have to go on, which is ' Knock Signal Circuit 1'.
-
No, engine was not running when I did test.
What does that mean then??
-
......
What does that mean then??
It means you get fault code 31 ...... :y :y :y
-
Ok so I can rule codes 12 and 31 off my list and just worry about code 16 then.
Where is the knock sensor on the 3.0 MV6 then. Is it the one situated below the oil filter housing??
-
There are two I think, and I don't know where they are. But I do remember seeing somewhere that identified their locations... can't find it now though.
I don't know if/how a faulty knock sensor would cause problems.
-
Check the wire to the drivers side knock sensor.
-
Without sounding too dumb
Where and which one is it Mark?? ::)
-
Sensor sits behind the alternator.
The connect for it is mounted on the cable tray on the front of the cambelt cover.
Follow the wire from the connector and check its not getting damaged by the aux belt.
-
As already mentioned, code 16 is Knock Sensor 1, which (according to Autodata) is located on the passenger side of the engine (red dot in image below).

ok, on way to get wet and have a quick look!! :y
-
So ... you're back to square one! Which side? :-/ You can either follow 20watts advise and go to the passenger side for No1 knock sensor or follow MarksDTM's and go for the driver's side.
:-/ :-/ :-/ :-/ ;) ;)
-
Lol, Vx are far more sensible than autodata....and hence the sensors are on the same side as the associated cylinder...hence Lambda 1 and Knock 1 are on the same side as cylinder 1.

What about relay 2 under the bonnet? ::) ::) ::) ::) ::)

Depends where the fitter clipped it into.

OK, spot on Mark (unfortunatly)
The cable to where it clips to the cover has got caught on aux belt tensioner and ripped it in half!!! >:(
Does this end go to the sensor or does it go to the wiring loom??

Your luck gets better and better don't it :-/
-
bloody hell andy your having a mare with this car bud !! if you need a knock sensor i have a few mate :y
-
Well I can only blame myself on this one as I put her together and must have not checked it.
Just need to work out if its the section that goes to the sensor or if its the section that goes into the wiring loom. If it goes into the wiring loom then Im worried! :'(
-
Thanks Mark will let you know. At the end of the day I like her, shes a comfortable ride and has plenty of poke and is just the right size for everything I do.
If you heard what my partents think about Omegas no one in the world would ever buy another ;D :D
-
Come on then you experts.
Which end of the cable is it that Ive knackered. Is it the sensor end or is it the end to the wiring loom :-? :-/

Look at the pic, which side of the plug did the cable break?
(http://i680.photobucket.com/albums/vv166/KillerWatt_1K/cable.jpg)
-
Its broken around the aux belt tensioner and I think its the left hand side of the cable plug thats had it!!

If it's left hand side, thats the sensor side.
Prices for new sensor as follows:
Main stealer
Up to engine number 08137540 - £42.90
From engine number 08137541 - £73.00
Trade Club
Up to engine number 08137540 - £33.45
From engine number 08137541 - £56.57
All prices are plus VAT
I'd personally just repair the cable, theres nothing special about screened cable at all.
-
Well atleast there is some good news from it.
I was suprised when it did not make the car go into safe mode. Is this usual or am I likely to find that this happens when I get in the car in the morning :-/

That will be the sensor part of the lead, the main loom section only appears outside the cable tray for aroun 50-75mm.
They can be soldered together successfuly (2 wires and a screen)
-
When you say a screen will shrink wrap and elec tape do as a temporay repair??
-
What is a knock sensor as they get mentioned quite a bit on here.
Ignore that, the link says it all. I wouldn't have guessed it as a microphone though.
-
Got to admire your patience, I would have valeted it with petrol by now :y best of luck
-
OK, Ive just been out and had a quick look at where the cable is situated and how easy it would be to rejoin the cables for the time being however this is not goint to be easy.
The main section of the cable that comes up to the multiplug is easy enough however the other section only sticks out by an inch so is insufficient for me to cut back clean up and solder together. Plus with it being so close to the aux tentioner their is hardly any room.
Any idea what route the cable takes back to the sensor. I was wondering if I could pull it though and reroute it to give me more slack :(
