Can anyone offer help?
My engine is making horrible noises!
for a while my car has started ok and run ok for 15 - 20 mins and then has lost power and the EMU light comes on. The car still drives but pulls away very slowly from stationery. If after a while I stop the engine and re start, the light goes out and stays off and the car drives ok for as long as you like with no prob.
I have had a diagnostic done with a Snapon tester and it says there is a fault with the crank circuit.
I have just tried to start the car while it was a bit warm and it is really rough starting and making horrible rattling noises. Any idea what the noise might be, I was arranging to get the sensor replaced but the man I use is away at the moment so any advice would be welcome.
Cheers
-
with 2.0's its either the cam or crank sensors, just replace and all should be well again. Use geniune sensors.
-
thanks for the quick reply but it's the horrid metalic rattling that worries me - do you think the sensor could have fallen apart?

Its possible, the cam sensor actually sits between the 2 cam sprokets, its possible thats fallen down or something and its rubbing against them.
Thats easy to check, just pop off the cambelt cover, or just remove the black ecotech strip, the sensor is at the front of the engine, you should see a wire popout out the fron the black strip.
I would have thought a dis lodged cam sensor would cause horrid noises, i think the crank sensor would just make a rubbing noise :-/
But then again i am no expert
-
Cheers for that info, it makes me feel a bit better. If the crank sensor is buggered, how easy would it be for me to replace it myself? - (trying to save some money)
-
if you have metallic noises, start by checking the state of the cambelt tensioners!
-
Yep, check the cambelt and tensioners.
And do a paper clip test and post up the REAL fault codes! :y
-
thanks for the advice you lovely chaps!
I will go back and have look tomorrow where I have abandoned the poor thing, incidently will the paper clip test work on a 'V' reg? p brill if it will.
Again thanks for the help.

paperclip test will work
-
Can someone tell me where on the engine I am likely to find the engine code for the paper clip test ? [edit][/edit]
-
you do a paper clip test to get the engine codes ;)
-
what I meant was where on the actual engine will the engine type details be so that I can tell what ECU type I have not the actual fault codes, I think it is a Ecotec engine but can't remember and It's about a mile to walk to my car so I want to be sure
-
Engine is the X20XE. As already stated, `clip it and post up the codes. I`d advise you to print off the details in the "How To" guide and take with you :y
-
thanks a lot - wish me luck tomorrow!
-
Ok been and done the clip test and got 0335 as the result so I assume that the cranckshaft sensor is knackered. I have managed to drive home and the horrid grating/rattling noise has reduced but still there.
Is it practical to try and change it myself? and can anyone suggest a good place to get one other than a Vauxhall dealer.
-
Best to get genuine, mabe someone local has a trade card?

stick with genuine part.
easy on 2.0 without aircon, fiddly with aircon.
doubt that is cause of metallic noise though! check cambelt!
-
hanks, mine has aircon, any guidance welcome
-
checked the timng belt - all is well no damage and seems tight
-
is the cam sensor intact? look between the cam sprokets with the cam cover off
-
It seems ok as far as I can tell, I would add a pic but I can't quite work out how
-

pay particular attention to tensioner and water pump.
-
they both seem ok, there is no play and they look fine.
Thanks to all of you for your time.
I will need to take off the crankshaft sensor to get a replacement, as I said I have aircon so how difficult is it to get at ? -any special tricks?

Hi Mick,
this sensor is bad? Or only dianostic says if error in sensor?
Because 1) checkit diagnostic and 2) tested this separate sensor
same as here http://www.omegaowners.com/forum/YaBB.pl?num=1234899864/8#8
And, small question. How are old oil? If very old, includes much metallic dirtiness and impedance hereof sensor is changed.
Correct values 500-800Ohm.
Often helps dismount sensor, clearense and mount back.
I would have done that before change crankshaft sensor.
The mere fact exchanges sensosr is involvement, becaus off european cars cabel from off sensors is under oil tube. I don´t know as i version with RH steering.
If changed sensor, must ease away oil tube because of extraction cabel of sensor. Dirty work.
I hope if undesrtand me :-) Bay

Water pump or tensioner
Check it carefully
