From what i can see the plug is supposed to be driverside firewall near break master cylinder..its an c20let with its original loom out of an astra ts and all turbo engines should have alambda sensor right ?

Hi caranx............what planet are you on then  ;D ;D ;D

The lambda sensor is screwed into the turbo exhaust elbow ......and the harness runs back to the bulk head offside where it plugs into the socket
part of the plug and then goes to the Ecu. This should be on the bunch of wires running along the bulk head.

Of course there has to be a lambda sensor because the engine Ecu needs to know how much fuel to mix with the oxygen for a clean burn.

As you have noticed the engine is running rough due to its absence.......the loom you are trying to locate is under the plastic cowling cover that folds down over the edge of the bulk head.

I hope this helps......keep us informed ;)

hello turbohead sir,i thank you for you reply and yes it makes sense to me  but iv got a spot of bother here lol  , its a 92 red top calibra c20xe shell my old one  , when the welsh plug went and i kinda cooked motor a wee bit i decided to engine swap from a astra katted ts, c20let , so the car now starts and runs well was a hell of a job just me in the driveway like hahahah  ,  its running  bit rough and ecu says lambda error but i cant find the plug on the loom ....i got this turbo motor with its own engine loom and ecu from donor and stuck it all in but that elbo you speek of just has a gub screwed into it

You have done well to swap the engine ;)

When it comes to auto electrics.......a word of caution is needed. There would be so much technical stuff to learn.......and much damage you can inflict on the ecu :-\

What I suggest to you is try to get a mobile Auto car tuner to have a look at your engine set up. They are trained to fault find problems that can cause problems to do with all engine faults and will also fix or advise you of the solution you need. You can find them locally or online and they carry not only all the diagnostic tools but sometimes years of knowledge .

I think you were trying to say that there is a bung of some sort on the elbow that plugs the threaded hole that the Lambda sensor would occupy.

The loom coming out of the Ecu you fitted should have a wire that terminates with a connector for the lambda sensor to plug in.

Other than that maybe some other club member can throw more light on this subject.  :)

That's the spirit 8)

It is a challenge to keep our Calibra's tip top and getting through the dreaded MOT.........looking forward to seeing your photo's.

The older a car gets more and more problems rear up to kick us in the teeth :(.....but the more parts you replace the more reliable your Calibra becomes.

The benefits of all the knowledge club members bring to us......is priceless to say the least. 8)
