well sort of off, coming home yesterday on the motorway, pulled into centre lane to overtake, kicked down and suddenly without any input from me it roared away and redlined, then revs drooped and lost power, managed to pull safely to hard shoulder. On stopping found engine still running and responding to throttle, EML light on though, checked everything and found no obvious fault, back onto motorway and off it went as normal, although a bit rough to start.
This morning started with short run no EML, followed bit longer run no EML parked for 20 minutes came out and since them EML is on.
Not done paper clip test yet, but any ideas of why?
car is F/L 2.0L running on Petrol when it took place
-
Throttle has stuck open for some reason, the pedal didn't get stuck under the carpet mat did it?
-
mark not as far as I was aware but would not account for EML light would it, just checked it again and it is out, all very strange
-
Does it have cruise control?
The only things that can actuate the throttle on the 2.0 is the throttle cable (i.e. your foot) or the cruise (if fitted), hence I wonder if during kickdown the cable or throttle pedal has stuck
-
ah yes see where you are coming from with that one
-
well just done the codes and none the wiser, it flashes 10 times, then three then three which I think equates to incorrect RPM signal so what next?
-
And what comes after the 2nd 3? Also, not that if multiple codes exist, you need to count them all (each one will repeat 3 times)
-
ah missed one out I get 10 335 then it loops back to 10 again
-

And after you've had 3 lots of 0335? (10=0)
-
nothing that's all I get just loops round same figures
-
0335 is Crankshaft Position sensor "A" circuit malfunction
-
0335 is Crankshaft Position sensor "A" circuit malfunction
is that the same as incorrect RPM signal? as that is what the code lists on the maint section
-
Yes and is the correct (and more useful/descriptive) one for the Vx setup
-
right so now we know what the code means can someone tell me what needs to be done, out of interest today when using car first off no light not until it got warm has the light come on, only think that I can notice is a very very slight sluggishness on move off apart from that it seems ok.
All advice welcome as I want to sort this.
-
Its pointing at the crank sensor, behaviour hints at this to (they are more liable to cause issues when hot)
-
Mark ok makes sense, so basically replace with new one, to confirm it is the crankshaft sensor that needs replacing, if so is it the same procedure as for the 2.2 tdi in the how to section as nothing for a 4 pot there.
-
anyone done this ( course you have) so any pointers, brand new with no discount £45 :'(
-
Genuine is recommended, procedure is the same as for the 2.0 16V (no guide on here but plenty on the web for the Vectra etc)
-
Mark going gen, looked at that well know auction and how can you relate gen price to something along £7 thanks for the tip on where to look, let you know how it went
-
Mark final one looking at some of the sites they comment that if you do paper clip test without engine running you will always get a fault, if I have engine running then no flashing lights (cool engine and fault light out) but on here it just says "turn on ignition"
Another pointer is I have had it cut out for no reason once or twice
mine is a 2.0L 16 v
Sorry to keep on but want to make sure not wasting time :y

Yes I was using the standard obd2 listing, where can I find the vx setup list? It would be handy on this forum if it isn't already. The generic list only has 3 mentions of RPM:
0505 Idle control system RPM higher than expected
0505 Idle control system RPM lower than expected
0654 Engine RPM output circuit

On the older ECUs with 2/3 digit fault codes, you get a 31 if not running, or 19 if ECU definately believes its misreading crankshaft signal.
2.0l from about 1997 uses the 4 digit codes, so 0335 directly relates to earlier code 19.
-
When you say its cut out, was that at speed or when idling/slowing down?
-
Slowing down

Did that, searched for 'OBD2', 'OBDII', 'OBD', nothing. Found it eventually buried under a paperclip, then a link in the second post down here: http://www.omegaowners.com/forum/index.php?topic=90581.msg1155463#msg1155463 (http://www.omegaowners.com/forum/index.php?topic=90581.msg1155463#msg1155463). ::) ::)
And after all that it seems the official OOF description of 0335 is exactly the same as I said originally >:(. Seems like the hidden OOF guide is wrong? ;)

Why do you have to behave like a dick? I posted links trying to be helpful - won't bother next time >:(
