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?
-
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?
-
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! :y

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 :y

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

I ask the question as there are a number of things that can cause cam sensor errors, one of which is a slack belt or a miss timed system.
Its a good bet that as the belt has not been touched that all is ok here.

Does this make any difference to your diagnosis then? Or was it just a question? Thinking about it, are you thinking the belt may have stretched? Be on its way out? Hence putting timing off slightly?
EDIT: sorry must type quicker!!

Update: have the car back at home now, still doesn't start very well at all!
I have done the pedal trick:
ECN245248 means P2452 relating to Particulate Filter Pressure Sensor
ECN34028 means P0340 relating to Camshaft Position Sensor Circuit
ECN38008 means P0380 relating to Glow Device
I think I have the above correct, please let me know if not.
The P2452 doesn't always show, assume that is because the car has not been run for a LONG time, and just idled.
The P0380 maybe means failed glow plug? When you turn the ignition on, the glow plug light stays on for a bit (longer than it used to) and then it flashes. Not going to be helping the none starting I assume.
P0340 I recon is the same fault as it always was, and after Mark Calib DTM's suggestions I think it is the crank sensor as the cam sensor has already been changed.
Any suggestions what to do now? How easy is the crank sensor to change?
Cheers in advance.

change glow plugs and crankshaft sensor,without them its not going to start properly

Morning,
Yesterday finally got round to changing the crank sensor, done but no better, in fact worse! Car still won't start. Did notice the crank sensor had oil all over the end, assume that is normal? Have noticed that the glow plug light does not come on at all when ignition turned on. Can just sits there and cranks over happily, no sign of life at all. Any thoughts?
Not sure if these are related but the car also has the following issues:
1 - Deadlocks not working
2 - Heater fan not working at all now, was only working on 4 , now nothing whatsoever.
These problems started after the new fuse box and cam sensor were fitted by the garage.
Look forward to any suggestions as at a complete loss now, thought the crank sensor would solve it.

if all this has happened since new fuse box being fitted i would take it back and get the garage to sort it out
