If the engine is a Y or Z22XE then the cam sensor is GM#90520850 = Siemens 5WK96052.

Is the spanner light coming on? Immediately at engine start?
Are there any fault codes?
What make & model is the sensor you bought? And does it have "Siemens 5WK96052" moulded onto it?

Because buying them from anywhere else is a lottery.

As you have found out.

You need to buy, and fit a genuine sensor from a genuine Vauxhall dealer that you genuinely need to walk into.

And take the Eurocrapparts one back for a refund because it is defective.

The P0110 is the intake air temp sensor. Sometimes separate and sometimes part of the MAF sensor. Check the plug and wiring.

It’s impossible to fit the Cam Sensor backwards.

If you've had the throttle body off for cleaning, make sure it's correctly plugged back in.

However I seem to recall reading somewhere that it's possible to have it sitting not fully located (the pick-up end sitting high). So worth checking.
A new GM sensor might be a available as a special order ex Opel in Germany. Payment upfront, non-refundable unless defective and about 7 days delivery. Ballpark cost £60-£100. And you need a franchised dealer that's will to and knows how to place a 'special order'.

The GM sensors say GM & 90 520 850 on one side and SIEMENS & 5WK9 605 2 on the other. Aftermarket parts might not work but a genuine Siemens part will. A genuine Siemens part will have the Siemens logo and part number. If it doesn't have the correct number then it's pot luck. If you can't get a Vauxhall part then see if you can get a VDO (Continental) S105570001Z. The VDO parts are Siemens.

No, it's just that they're a coil of really fine wire. That's not a part that responds well to cheap manufacturing/quality control. Which is what makes buying them(and crank sensors for any engine) such a lottery. Buying one from a franchised dealer improves your chances of getting a working and durable part far more than the cost increase.

Especially as the codes tell you that the gearbox needs replacing.

Also, if you get no joy from VX, then ring a GM Dealer in Jackson ville, Florida and give them the part number Enceladus has posted. If it is NLS, they should have the current part number. Price tends to be the same as here except in $.  :y

That the Vdo one is Siemens and will be good to go?

I suggest that you post up a timeline of the original problems and what exactly you've done in trying to resolve them. EG what was the first problem to occur?

A quick search suggests you've replaced some of the bulbs in the binnacle. Now you have a code P1781 which suggests either the EML or the spanner light isn't working. You've replaced the MAF. You've replaced the cam cover seals and the plugs. But did you replace the ignition module?

Seems to me that you're in danger of throwing a lot of money, time and effort chasing these problems.

Okay first problem missing on cold start and lack of power over 30,
Then slow oil drip from back of engine,
Put in garage for a diag,
Report cam cover leaking internal and external, plus maf had no reading,

I have since replaced cam cover gasket new plugs new coil pack air filter and Maf,
Car still running rough on tickover
Was told that the codes I have are referring to cam sensor so changed that for a cheap aftermarket
One, car won’t even start, put original cam sensor back runs but rough idle, so now got to order vx one so the chaps here say

P0650 is the EML light. ;)

The other two suggest the gearbox is dead. The correct cam sensor will fix these. A duff cam sensor will show these two autobox codes even on a manual.

I told you so re the consequences of buying a cheap sensor :-X

Unplug the MAF and report back. If it improves running, then I would replace that with a VX sourced one, rather than a hookie one that's on there.

If it doesn't change anything, try the following...

Unplug the engine ecu for 30 mins and use the time to check all the previously disturbed electrical and vacuum /breather connections.

It won't necessarily fix anything but it will temporarily reset it in order to see what returns.

Sorry, typo on my part, I actually meant Code P0650 above which implies a malfunction of the MIL/EML circuit.  EG a blown bulb or a bad earth.
So something wanted to set the MIL on. This is P1700 which is the TCM (ECU) for the autobox seeking to switch the MIL on, but failed as the circuit was/is faulty.
So what was the triggering fault? That was P1781, which is model specific. Now whether or not there really is/was a P1781 or any other fault in the autobox is a different matter, since a bad Cam sensor can and does trigger spurious autobox faults.
My point was that you shouldn't have the P0650 since you renewed the bulbs in the binaccle. There may be some other issue putting the powertrain into limp mode.

Do both the EML and spanner lights come on with ignition on but not yet cranked over?
Do they both go off when the engine is started?
What did Vauxhall say about a new Cam sensor?

Okay chaps,

Update,


Changed cam sensor for genuine 1

Car running good now in general

Have changed blown engine management light,
Cleared codes been for a spin no codes or lights
On return,

Only thing is and I have had this for a long while
Pull of gently it’s fine but put your foot down fast from a standing
Start it misses just for a split second but never the less it does
It when reved in park to so it’s not just under load,
Can live with it but it’s annoying any thoughts chaps,

Firstly, re the Cam senor... I told you so.

Secondly, what you describe is normal behaviour for electronic fuel injection.

The stumble is down to the delay between the accelerator pedal and the throttle/injectors. Basically it takes a split second to add fuel and air, by which time you have lifted off again and it takes a split second to respond... Basically it stumbles because it is struggling to work out what is going on ::)

I would try and understand how it works before complaining that it doesn't.  :y

To that end you may find cleaning the throttle body will help, but it is also likely that you need to adapt how you drive it... The drive by wire accelerator is progressive, not an on/off switch. The engine vs size/weight of the car highlights it, especially with the auto box...
