Plug under scuttle rear right hand side (passenger) of plenum, sensor end on passenger side of engine just behind and below oil filter.

[Varche]

The sensor is down near the oil filter on the side of the engine and held in by one small bolt. The cable then is routed up out of the way of oil and heat behind the exhaust and into the cable tray. I think for your engine there are two types. One with an oval connector to the loom and one with a square one. You need to know which one unless you are lucky enough to have a part number on the sensor itself.

Cheers guys. I'll try and find the plug to suss out which one I have

[doz]

Ok I've got the plug and it's the more square shaped one . Where's the best place to get one and are they a lot of dosh?

The new cable should be genuine Vaux and should be routed up out of the way of oil pipes and exhaust...Vaux in their infinite wisdom decided to run the original inbetween the oil cooler pipes!! Cut the ends off the old one leave the cable there if unable to remove...

Ok time for a update. I have replaced the crank sensor for a genuine part and it made no improvement. So I've done compression test and they are to say the least brillant. Next to no difference and all nice and high. So I've stripped the plugs (look old),leads (look older!!) and the dis pack out. I plan on replacing all 3 items. The fault codes remain the same. One thing I did try was unplugging the camshaft sensor while it was running. This didn't make any difference to running. So If after I've done the dispack etc it dosen't run right I'm well and truely stumped  :-/

[Bent valve]

Have you checked the valve timing yet?

[doz]

Valve timming is correct and as I said the compression is excellent. I would of also thought the compression would be all over the place if the timming is out.

'dangle berries'!! This has gone tits up big style. I have replaced the crank sensor without improvement. So I replaced the dis pack,leads and plugs without improvement. While I had the plenum off and had access to all the plug holes I carried out a compression test. All cylinders were excellent. I should of really disconnected the ecu to do this but instead I unplugged the injectors. Well when I put it back together I now have 11 fault codes!!! and I can't clear any of them. I don't believe for a second everything which was unplugged has now gone wrong. Think I'm gonna need some help with this one.

69 intake air voltage low
19 incorrect rpm signal
94 hall sensor voltage hi
49 battery voltage hi.
144 immob no signal ( still starts???)
57 idle air control valve volt low
21 TPS volt high
129 EGR feed back volts low
133 intake manifold valve2 volts low
71 intake air high volts
73 maas air flow sensor low

While I've been working on this I came across a pipe and a electrical connection not doing anything under the airbox. The pipe goes through the inner wing while the wire dissappears back to the front of the bumper. I also had a look at the state of the wiring under the inside the ecu box and there appears to be lots of wires joined together I'm not sure if this was done by vauxhall or a bodgeitandscarper

[Bent valve]

By the look of it I'd say bodgeitandscarper rather than Vauxhall..

[doz]

Ok time for another update. I have now replaced the loom and ecu. It looks like the ecu was at fault as most of the fault codes have cleared. The 4 fault codes I have are
144 immobiliser no signal
145 immobiliser wrong signal.
74 mass air high voltage
69 intake air low voltage.

Also the car won't idle less than 2k. I guess I could have air leak but I was wondering if with the EML light on would that raise the idle that high. Oh and bloody ignition switch fell to bits on me  

Anybody got any ideas?

[Andy B]

.....

Anybody got any ideas?

Box of matches & a gallon of 4 star! :-? :-?
Use your Carltons!!!  

[M Kerr]

  Whilst still struggling,Doz, are you atleas fising on 6 now all the time?

[M Kerr]

I meant to say... those wiring pictures looked a disgrace.  I'm sure Ive got that "loose wire" connected and if not mistaken somewhere on the multi-ram. That mar solve a couple of your fault codes.  I try to have a look at mine and update as soon as pos but dont rely on me too heavily for that as work may not allow for WEEKS unless I get a chance tomorrow.
