was going out to change my intake from stock to just a normal short ram intake, and this is what i ran into... help please








I unpluged this connector becuase it's part of the factory intake stsyem..... then i plugged it back in and now my check eng. light wont go off...?!!! doesnt run any different... wtf did i do?... ( 2000 civic ex coupe )

 

Unplugging and plugging that sensor back in with the car off will not cause a CEL.

Did you connect your IAT?

 

most hondas have a back up fuse if not disconnect the battery for 30 min. and what that thing is it is a mass airflow sensor or something to that effect.

 

yea just stopped by honda.. they said dissconect my alarm and dissconnect my batt for 30mins.. and the light should go offf.... now time to find the alarm thingy. haha

 

MAP sensor Manifold Absilute Pressure sensor it measures the pressure or amount of vacume in the intake manifold

 

so wtf... how do i get to bypass that so i can have a normal intake stsyem, not factory that **** is wack.

 

remove the battery's neg cable for like 30seconds - pop it back on. CEL should be gone

You did check the cel though, right?

 

CEL?.. HAHA

 

That is a Mass Air Flow sensor, just put your intake on, don't try to bypass that because it is one of the main controlling factors of fuel trim. Leave that sensor alone and put your intake on, there is no reason why you should have to remove that to put an intake on.

 

look at the pics... the wires go down and its connected to the intake tube.

its not a mass air flow sensor, its a MAP sensor

 

Im pretty sure that the plug in the tube is your IAT, if you buy an intake that is MADE for YOUR car and not some auto zone **** then it should have that plug.

Why would there be a map sensor on the throttle body? The only vacuum that can be measured there is ported vacuum, i.e. when the throttle plate is barley open. After that there is none.

EDIT: I just looked it up and I guess it is a MAP sensor, very odd placement of it though.

 

After you install an intake you have to "reset" your ECU so it can recognize the increased amount of airflow (or decrease). Simply disconnect your battery cable for a few seconds or minutes whatever u want then reconnect it and you're good to go. No CEL (Check-Engine-Light).

 

ok so what your saying isssss..... if i buy a intake for my year civic and everything it should have the extra little plug for the map senors?.. becuase it is connected to the pipping of the intake on the factory setup.

You cannot bypass the MAP sensor.

Hondas use map sensors, not mass air flow sensors.

Do not even bother posting in threads to give advice. You only further the spread of misinformation.

The harness going to the MAP sensor has two wires branching off of it (the red and green wires). Those wires connect to a sensor in the intake pipe which is called the IAT (Intake Air Temperature) sensor. Make sure both of these sensors are plugged in.

All Hondas with OBD systems have MAP sensors on the throttle body.

This just shows you how ignorant you are.

If one does not reset the ECU, it will not throw a CEL.


Use this FAQ if you're not familiar with how to pull CEL codes.

They're talking about the hole in the intake for the IAT sensor. Read my above post, and let me know if you have any more questions.

If your intake does not have a hole for an IAT sensor, simply drill a hole in the pipe.

 

wtf... drill a hole and ****... i dont want to do that hahaha, i guess i'll just go waste my money on some intake that has the right "holes" or whatever and gain my 1hp.

Is your IAT not connected?

BTW, don't be afraid to drill the hole. If you're too hopeless, maybe you know someone who isn't as hopeless.

 

yes its connected.

no i dont want to dril.

wouldnt say hopeless.

just want everything to be done the right way.

You're clearly have little to no experience.

Please let me clarify that drilling your intake pipe is not "ghetto" by any means. It's simply a case of modifying parts to make it work on your setup.

There is nothing wrong or incorrect about drilling the pipe. I would not have suggested doing so, if there was.

Damn right. Don't be say shy to get up and drill that damn hole. It really isn't that hard. All vtec D16's have that. My D16Z6 has it and it's just the map sensor. I don't understand why you would have to drill a hole for it??? It does not take reading's from the anywhere else then the throttle body it's self. That must be the IAT is what need's to be plugged into your new intake. What brand is it??? The AEM intake that I have is universal for all civic's from 92-99. If you just don't have the hole then find out the size and drill it. If you can't do that then go to a mechanics and tell them to drill it. I am pretty confident that they will be able to figure it out .

Its obd2 the good ol' trick wouldnt work for him.

Honestly he could just leave the sensor plugged in, n let it hang not connected the the intake at all, then reset the ecu n the cel would go off n not come back on.

Just a suggestion tho, your intake must be cheap as hell... ractive maybe, it will prob end up rusting out in about 8 months so dont sweat your .5 hp, u only got a y8 anyway the only thing the intake does is make vtec a little louder.

OBD2 cars can have codes pulled from them in the same way that OBD1 cars can.
