Morning,

After changing the fuse box under the bonnet for a shiney new one, resolving the horn issue, the car with the spanner light is still on.  Been diagnosed by the garage using "My Naff Code Reader" and found to be a cam shaft sensor fault.  I know these are an issue on the 2.2 petrol Omega engines, but are they common on a 1.9 diesel?

Is it as easy to do on the Zafira diesel?  And assume genuine only as normal, or would a pattern suffice?

Cheers

Phil

Never ever seen mention of a failing cam sensor

Easy to get at though.

I assume the timing is ok?

[philsteward]

No idea, how would you check?  It tends to turn over a lot before bursting into life, doesn't seem to make any difference if it is warm or cold.

Thats more crank sensor I would say, any codes ? (pedal trick works)

An update:

Garage said the car got very bad at starting, if it did at all.  They have put an after market cam sensor on, and it has improved it a lot, but it is not perfect.  It is still showing a fault on the cam sensor!!  I am not too bothered, as I think "something else" has gone and maybe caused the old sensor to fail, hence still showing a fault, I will be replacing the after market sensor for an OEM one when I get the vehicle back, if the original one has failed.

I am not in a rush for the car, so have asked them to have a bit of a look again with their "My Naff Code Reader" software.  I will get it  off them do a service and use it for a bit, including hopefully popping down to see Mark Calib DTM for a proper diagnosis session - blind hope that Mark will read this and say "yes"!

Will try pedal trick when I can, and let you know what is going on.

No problem plugging it in for a look see.

Any history of a cambelt change?

[Marks DTM Calib]

I should add that if the crank sensor is supsect then you can get cam sensor faults reported (as the crank sensor is considered to be the reference)

Nothing according to the service book, when is it due?

Anyway of knowing if the crank sensor has failed other than by substitution?  I am warming to the idea it is that, however I would want to replace with a genuine party, but if it is not then I would not be able to return the part!

Are these engines as bad with pattern parts as the Omega ones seem to be?

Oh and thanks!!  Will be in touch, what is the best way to contact you?

Not that straight forward but the symptoms do point towards it.

Its not the engine's that have the issue, its the quality of the pattern parts! 

[philsteward]

Yes, agree with that!

Would you be able to get any more of a definitive answer if it is the crank sensor with the Tech 2 kit (and of course your knowledge of using said software?!)  Is it relatively easy to change the crank sensor?  If I came down armed with a genuine replacement, could we fit it together?

Also, do you know the interval for the cambelt? 1.9 turbo diesel (120Bhp) engine in 2007 car?

Autodata quotes 100,000 mile or 120 months,but Mdtm may know better

Thanks!  Therein probably lies my answer, vehicle mileage 98k!!

Correct, water pump to be done at the same time to.
