Think you can get the map sensor from usa for like 40usd its not used in any uk cars so its an import job I would have to look up the number its been awhile since I last dug it out
If u could bud that would be great help and saves paying over the odds🙂

I also have the code p1516. but only if I let it go through bulb check before starting.
strange thing is that even with the code live/active it can be cleared and doesn't come back until next time you go through bulb check. swapped many parts, checked all the plugs, earths ect. and all I can put it down to is to much resistance in the wiring in the corsa, the fault has been there since I fitted the z22se. didn't have the fault in the Vectra before.
seen similar faults on machines before and adding a second power supply to the controller and better earths helped so this will be my next step when I get around to it.
too much power being drawn through 1 circuit can lead to a drop in voltage enough to trigger the fault codes we have.
Same here if I clear the code it runs great till it happens again. It never does it in the dry only when wet and I had this issue around this time last year but it fixed it self🙁. Ive contacted jeff from the states to get a price on a tb and I'll get a new map sensor when Carl can find the part number to order it from the states.
I'm planning on taking the charger off tomorrow to measure the coolant hoses on the intake manifold as I want make sure I got the right bends on the new silicone hoses for it. So I'll give the tb plug and pins in the tb a good look over and apply a healthy smear of vasaline and see if that makes any difference in the wet.
