Okay most Honda's and all old hondas for that matter like your car are "speed density" systems that use a MAP sensor not a MAF(mass airflow). So to answer your question your car doesn't have a MAF. It does have an IAT(intake air temp.) sensor if you need the location for that. I can provide manual pictures but maybe you should just tell me what you're trying to do so I can help you better.

Reply to Kyle Northrop's Post: Please let me know where the IAT sensor is located with the picture of it, i want to clean this to start my car, i was having problem in hot weather the car was not starting but when it cools down it is ok. I replaced the Main fuel relay and NOW makes a click before it was not and now i have to clean the sensor so it can read the right temp in order to start the car. Thanks for your help you are right that it has IAT sensor.

It sounds like the starter solenoid if you have just a "click" when starting. They tend to fail hot and it's not uncommon. You could tap the starter and try and see if it starts and you'll know that's the problem.

I can give you the IAT picture but it has no control over the engine's ability to start the car. The computer uses it to determine air density. If it fails it won't cause a no start.

If you need more help I'm here.
