Hi,
can anyone point me in the right direction as to the cure for these codes please
P0155 O2 Sensor Heater Circuit High Voltage (Bank 2 Sensor 1)
P0300 Random/multiple cylinder misfire detected
P0306 Cylinder 6 Misfire Detected
many thanks in advance :y :y
-
For 300/306, check plugs for oil/water on the 2-4-6 bank, worth checking 1-3-5 as well.
Is your EML on?
-
no eml on did come on then went back off did cam covers aug last year with genuine ones from andyc also changed plugs as well just happened this morning when swmbo went to the shops
-
how old are the plugs, also how many miles on coil packs?
-
plugs aug last year and coil packs don't know if original then 130k :y
-
Check for water around no 6 plug well due to a leaky scuttle.
-
just got the coil pack off and no water or oil in or around the plugs plugs look ok can't see anything on the coil pack either should I change the plugs to eliminate them any suggestions welcome thanks :y
-
you could always swap the plug to another bore to see if the problem misfire follows it - could be the actual coil pack itself with it coming up random misfire - check the condition of the rubbers that fit over the plugs - often they get damaged if its not removed correctly - there is a special tool to remove them - i just use two larger bolts to do it
have got a brand new one in the garage but just checked and its 1-3-5 bank

if I need the coil pack and you are selling it how much would you want for it :y
-
Might be worth check bank 2 trims, given the codes from bank 2 lamda.
Visually inspect the missing cylinder coil pack. Any signs of expansion, or rust in the cracks that may appear, is a bad sign...
-
no cracks expansion or rust changed the plugs now seem to be fine. also who's the best to get the trim checked :y or closest to chester

And the result/fix?
-
all fixed it was plugs there were a couple of codes in there which were random codes but all working and a1 very happy :y plugs are only 6 months old as well
-
codes were :

All codes / trims reset so can monitor for any reoccurance.
-
Thanks for the info Jimbob will keep my eye on things :y :y
-
If those live readings were before the codes were cleared, all well and good :y
If they were after the codes were cleared, revisit Mr Greedy in a week or 2, and get live data readings before clearing codes :)
-
think they were after the codes were cleared :y

Bugger.
Give it a week, then revisit. And slap him repeatedly for doing it in the wrong order ;D
-
I could have it all the wrong way round ;D
-

Slap him anyway. He probably deserves it ;D
-
I cant do that he's a very nice man ;D ;D
-
I did clear the codes....forgetting that reset the trims by default :(
sorry
As I said at the time, anything untoward, and we can reread from a clean slate :y

Thanks Jimbob will be in touch if anything happens :y :y

Sounds like the perfect excuse for local Chester members to have a mini meet ;)
...see, you did it on purpose, really ;D
-
That sounds like a plan we will have to get one organised :y :y
