Help people I have the above car and have plugged in my diagnostic tool and its reads p0341 camshaft position sensor (a) circuit bank 1:range/performance. So bought and one one from tps fitted still the same I'm now thinking timing chain has jumped a tooth need to set timing up to check I take it rocker cover has to come of to set it up to make sure all Mark's align up or is there another solution to this problem.

Cheers scot

You need to check the timing for sure, I'm used to measuring inlet valve lift at TDC since it's the most accurate method, it means you need a DTI but you only have to remove the rocker cover to check that measurement.

If it's an htp it's a 1.2 not a 1.4?

If so, is it 6-valve 54hp or 12-valve 64hp version?

Either way, timing check involves tools that fit in various places, not rocker cover removal. 12-valve can be done without special tools.

I was assuming it was a 1.4 pushrod engine, obviously. If the OP doesn't even know which engine he has then a timing check is going to be a really tricky task.

Ok, so it's a 2006 car so it must be a 1.2 OHC.

 

I give up, you walk him through the timing check.

Let's allow the OP to clarify on engine type before anything else.

Sorry guys 1.2

I have a timing chain book for car but it only goes to 2001 need to get an updated book. Will need to buy the tools as well I guess

Good start, but 6-valve or 12-valve?

6-valve has no engine top cover normally,  and h, t and p on the back are all black.

12-valve has engine top cover with 12V written on it and the p of htp on the back is red.

 

Yes it has the cover on top and the red p on the rear 

OK, that's the one I can help with.

 

Take out number 1 cylinder spark plug (or all three for easier engine turning) and use a long screwdriver or similar down the plug hole to find top dead centre on number 1 cylinder (highest point of piston). Try to minimise turning the engine backwards compared to its normal rotation direction, so mostly clockwise as you look at the crank pulley bolt.

Once you're happy that that piston is at its highest point, take off the two covers from the nearside end of the engine head, which give access to the slots in the cam ends where the timing tools would fit.

Look at the alignment of the slots relative to one another. If they line up, all is good. If they don't, timing problem,

See here for one or two pictures. 2nd and 3rd pics in this post https://www.briskoda.net/forums/topic/235977-wideband-lambda-on-12-12v-azq-egr-valve-in-the-end/?do=findComment&comment=2785312

Thanks for this wine looks totally different to foing a corsa where u take rocker cover of and put it to tfc and slide a flat bar in the both cams then u know its tdc. That one looks like 2 separate bars to go in bit confusing but not hard 

Sorry for late reply I was busy on my mates vw bora. To let u know I have a small garage that I use as a hobbie for fixing up my own car/cars/friends cars 

The timing tool kit isn’t expensive and well worth a purchase if you have a small workshop. Plenty of these chains slip. 

 

Timing tool kit

^ It's a fair point, but isn't the crank locking pin something of a PITA to fit? I've never tried, but the location is 'unfavourable' for the amateur mechanic, I'd say? I think the screwdriver-down-the-plughole approach will give enough accuracy for diagnosis, at least.

Those two separate bars are just a home-made workaround to make it easy to see the alignment of the two cam ends, they're not part of any official tooling.  You may be able to see enough without any tools in the slots if the alignment is off.

It can be a challenge, it's OK to fit from underneath if you have a fairly flexible wrist of just take the driveshaft out.

 

Your method is fine for a quick check, but if you are taking the chain off you really need the engine locked in position.

Oh god yeah.

Cheers guys for this I really do appreciate this and the quick responses. I will keep you posted once I put it to tdc whith screwdriver and check the timing.

Ok guys eventually got around to timing it up and it's out bummer anyway looked like to many bolts in rocker cover so left that alone as some are probably attached to the cams. So took of side cover and omg 2x chains now its left like that until I get a timing chain book everyone seems to have item unavailable paddock spares has one for the sum off £117 lol and also need to get the locking tools any ideas guys or some more input please.

 

Thx scot

eBay for locking tools like Tech1e linked above. TPS or dealership wouldn't be much more than £117 for chain/tensioner kit I think? Should be plenty of those on eBay too.

Try to buy a kit with as many of the bolts and sprockets as poss, and the seal that goes in where crank nose goes through timing cover. @Tech1e or  @hutchysrs50 would be able to advise better than me. I've got the gear but not much idea on this job as it still hasn't needed doing on ours.

Ok ordered tools today also was racking my brains on who I know would have a timing chain book to loan me and out the corner of my eye on my startup screen on my laptop I forgot I bought a autodata DVD lol duh it's all on there so monday night I'm good to go.

Ok guys need more info please I have the timing tools where is the crankshaft sensor located is it in the side of the gearbox at the back of the engine or front of the engine I have found a plug with a long plastic bit that comes of a sensor is that the one help please I'm at the car now stuck

Crank sensor is on the engine block, not the gearbox, it's tricky to get at, even from below, impossible from the top I'd guess.

Left a bit and down a bit from the knock sensor shown in this picture, you can see the retaining bolt of the crank sensor  just below the lowest bit of the arrow

Wino mine looks lightly different to that my plup in connector plugs in from the top and is on with an Allen key bolt and my camshaft sensor is in a different place than that one
