MAF or equivalent?

[starchland]

just going through my mind thinking of some things I could clean/fix/tune up that would maybe restore my engines performance. any suggestions... also, i was looking at some toyotas and they have a MAF (mass air flow sensor) in the intake pipe, now was just wondering how our honda determine the amount of air being sucked in, it cant just be the tps sensor?

[Accord R33]

map sensor?

sorry to bring up an old thread, but my friend who drives a celica says that the maf should be hooked up to my intake. so what is the maf equivalent for our car?

[JaK FRoSTWhiTE]

Our Accords dont have MAF sensors.
Mass Air Flow sensor, which measures how heavy the Air comming in is.

We only have, MAP sensor.
Manifold Absolute Pressure.
They are located on the Intake Manifold, and some have them
mounted on the firewall, like the CRX i think.

everything look right to you guys?

[starchland]

yeah that looks right, thats how my intake is. So what you circled, is that the map tubing?

[flacopower]

i don't know, all i know is that if i go WOT below 3000 rpms my car has ZERO get up... i was talking to my celica owning friend and he said that is what happened when he didn't hook up his maf...

well i'd say the biggest problem is that your missing your valve cover.....heheheh

check all your wires connections on the fire wall. I think there are only 2. Then check all the ones on your intake manifold. With the car running check all your vacuum lines by spraying carb cleaner on all the lines. If the car runs different when you spray the carb cleaner replace that vacuum hose.... or better yet run up to a car place and get you about 10ft of 5/16 hose (i think that is the size, but i could be wrong) and rplace all the hose in your car.. then you have no worries what so ever. Check your spark plugs. Check your PCV valve. Sounds too me that one of your sensors might not be working right. Like the MAP sensor. I think the book says how to check it but i dont have that right in front of me....and we DONT have a MAF sensor....well atleast I dont, and i haven't looked one up on a honda yet...not to say honda's never had them..

Honda uses a Speed/Density system in order to run the engine. Basically engine speed (RPM) vs. Vacum (load) which is determinded with the map sensor.

[flacopower]

location of map sensor please...

[BustedLX]

The map sensor is located in the Vacum control box under the hood.

The map sensor is located in the Vacum control box under the hood.

uhh... sorry to be dumb but could you point it out on the pic???

the black box mounted to the left hand side of the firewall. Follow the 3 vacuum hoses leading from the throttle body and you can't miss it.

and on the picture it's touched a little bit by the top left red circle. It's the black plastic box. and by the looks of it his VIN number is printed directly above it.
