i work for firestone and have never replaced one. i doubt ull run into one thats bad otherwise the car just wont start. or run like crap then die. but most of them are right on the throttle body. it will say map or manifold absolute pressure on the sensor

to test it u gotta back probe it and ****, i cant remember but i got my sheet from Honda Electrical class in my car, i just dont wanna go outside
Just had to do this.
With the key in the ON position (not running) unplug the MAP connector and check the voltage between the yellow/white wire closest to the firewall (positive) and the middle green/white wire (ground) of the connector. It should be around 5 volts.
Plug it back in, and backprobe the engine side yellow/white connector (still positive). -Note: I used the (sanded off) intake for ground here, but I may just backprobe the green/white when i check it again.
Turn the key to the ON position again, and use your engine side yellow/white backprobe to check voltage. It should be between 1.5 and 3.5 volts.
Start the car and see if the voltage changes on the engine side yellow white wire with the rpms. Voltage should increase as vacuum decreases. This means at idle there should be low voltage (high vacuum) and at higher rpm's higher voltage (lower vacuum). It should be between 2.5 and 4.5 volts with the car running.
"manifold vacuum is high when the engine is idling and decreases as the throttle is opened allowing manifold vacuum to become equal to atmospheric levels." -Haynes

?? Im confused on what you guys are talking about or just too lazy to read your whole post. I just jumped the ecu and got code 3 for Map Sensor. But I was just wondering if all Honda map sensors were compatable with other stock honda Map sensors
No need to be confused. I didn't know what was going on at first ether. I thought they were going over the top answering your question. It was after all just a yes or no question. But I think they are answering this guy who jacked your thread.
