MAP Sensor

[NSX2XS]

OK, so will someone please tell - or better yet, SHOW, me where in the name of Zeus's butt is the MAP sensor is located. I looked in the normal places - throttle body and firewall - and can't find it, unless I'm looking right at it and am just clueless. I see references to the MAP sensor in the manual (but can't find an image or location of it in manual), I've read about it in posts, I've seen a picture SOS has of one, and I know what the part looks like. But I can't find it! One post said it was on the driver's side of the engine compartment and attached a picture from SOS that didn't have enough reference in the picture to orient me. I'm having really sluggish to non-existent acceleration at higher speed. I can stomp on gas and it either does nothing or starts dying. Someone said to check the MAP sensor, in addition to other gremlins. Seems a good idea, if I could only find it! Thanks in advance.

The MAP sensor is located in a control box directly under the strut bar. Here are some pictures for reference.

Here is an illustration of the inside of the control box that houses the MAP sensor.

On the SoS site, one of the MAP sensor pictures is for an S2000, so that may have confused you.

Thank you. That's exactly what I needed and I hope it helps others who search here in the future. As it turns out, that's the sensor I had come to believe it was, but didn't want to start pulling apart the control box without being sure. Also, if that's your car in the pics, I think I see a spec of dust . . . no, wait, that's just a shadow.

Glad this helped. Yes, that's my car. Just your average 145,000 mile 1994.
