Good day,

My vehicle has some of the faulty MAP sensor symptoms and I want to change it but I do not know where it is located.

Hello,

The MAP sensor for your Opel is located toward the back of the intake manifold. It is close to the firewall on the center upper part of the engine.
Unfortunately, I do not have a diagram since it is not sold in the US, so I can't provide that for you.

Let me know if you find it.

Thanks.

Hi there, thank you for responding to my question. But what I could find in that spot as marked in the picture I have uploaded is not the same 3-pin MAP sensor I have been shown at Goldwagen.

Can you upload a close up picture of the sensor that you found? If possible also upload a picture that shows the back of the manifold.
