hello,

I have a big problem, after the installing of the B18CR manifold, I realized that the TP- Sensor doesn´t fit, because of the 3- connecting pins, but my original harness of B16A2 (Del Sol EG2) have only 2 cable (2 holes) on the plug. Here is a picture of the B18CR Manifold:

What can I do, should I connect only two pins of the B18CR plug with the B16A2 plug? Please help me, because nobody can help me in Germany...

sorry for my bad English

Thanks
Michael

Any honda MAP i've seen has always been 3 wire, I think you've got the wrong plug. Pics of the plug you are trying to plug into it?

mischka89

I mean the other sensor, not the map sensor. I don´t realy know what it is, but I think that´s the trothle position sensor (tps), in the first two pictures you can see the map- sensor with 3 wire, on the other pics you can see the tp- sensor, this one has 3 wire too, and this is what I mean, because the plug of the original B16A2 has only two cables for this sensor.

I hope you understand me, and going to help me

Hi there.

It looks to me that you are confunsed with the plugs...

There are 2 plugs just alike that connect one to the TPS and the other to de MAP. Both of the have a 3 pin plug.

The other thing shown in the pic is a IAC valve, it has a 2 pin plug. You can easily noticed that the IAT has the same plug...

Can you take more pic so we can see what your problem is...?

mischka89

I have 3 plugs, but only one plug has 3 cables (3 wire), the other two has only 2 cables (2 wire), because of the b16a2 manifold.
But the new manifold (b18cr) has 2 sensor, which needs 2 plugs (2 wire) with 3 cables (3 wire)...
I hope you know what I mean.

Here are my original plugs:

map sensor plug with three cables: http://img577.imageshack.us/img577/1294/36328426.jpg

other plug with two cables (for the tps I think): http://img705.imageshack.us/img705/9718/48864373.jpg

third plug with two cables, too: http://img198.imageshack.us/img198/158/88414090.jpg

I would like to know, how can I connect the tps with the plug with two wires...

I can make more pics if you need them

94EG8

The 3 wire plug you have is actually for the TPS sensor, its the MAP plug thats missing. Some '92 - '95 Civics and '90 - '93 Integras had a firewall mounted MAP sensor bolted to firewall next to the fuel filter, if thats the case unplug the connector from that and plug it into the MAP sensor on the throttlebody. Or if you happened to use an engine harness off another car that had a firewall mounted MAP sensor you will not have a plug as its part of the cabin harness on those vehicles not the engine harness, if thats the case you'll have to hardwire it in. In any case neither one of those 2 wire plugs is for the the MAP or TPS sensor, nor can it be made to work that way.

Edit, you have a firewall mounted MAP, I can see it in one of the pics. I've pointed it out in the pic below. Simply unplug the connector from there and plug it into the MAP sensor on the throttlebody.

mischka89

thanks for the reply, but whats the function of this firewall? what have I to do with the other plug?

94EG8

Firewall mounted MAP sensor wont be used. Some B16As used a firewall mounted MAP sensor, its connected to the throttlebody with a piece of vacuum hose, most other engines have a MAP sensor directly on top of the throttlebody, both work the same. Simply unplug the one from the firewall mounted MAP sensor and plug it onto the one on top of the throttlebody and you wont have any issues.

mischka89

thank you very much!!
could you please tell me, what I have to do with the original map plug with 2 wire?
the other thing I would like to know is something obout the pipe on the picture, what is it for? the original b16a2 manifold doesn´t have a pipe like this.

94EG8

post a pic of the wires going into it so I can see the wire colors and I can probably tell you where it goes, it never was for a MAP sensor, its for something else.

Evap Purge Solenoid, if you don't have one just cap it off with a rubber plug.

mischka89

sorry my mistake, i mean the plug of the tps... on this two pictures you can see the cables, I mean not the tp sensor plug, but the other two. one of them I don´t need now, which plug is it? sorry for the amateur questions, but I´m really confuse now

--> here is a better pic: http://img233.imageshack.us/img233/1952/62989380.jpg

is the right cable, the plug for the Evap Purge Solenoid? can I take the eps form the b16a2 manifold and use it with the b18c manifold?

94EG8

Plug on the left is for the IACV, plug on the right is for the evap purge solenoid. You can as you said simply reuse the one from the B16A manifold.

mischka89

ok, this is my last question...
the holes in bracket (on the pics) for the manifold doesn´t fits with the b18cr manifold, should I drill two new holes or can I install the manifold without this two screw?

but anyway, thank you very very much for your help 94EG8

94EG8

You can do either, Personally I would just remove the bracket.

You're welcome

JDM4mee

I totally agree, just make sure that all of the nuts are well tight on the intake manifold so the don't come loose in the future. Just my personal thought...

mischka89

ok thanks for the reply

mischka89

hello,

after the installing, I find two new questions/ problems:

1. what is this hose for ? http://img543.imageshack.us/img543/6478/foto0099p.jpg

2. I can´t realy explain it... let me try it: after I push the gas pedal, the speed going up, than I put my feet away, the speed decrease until ~1400rms but after it, the speedometer needle increases to 1500rms...
Watch my video and please try to help me to solve the problem, or is it normal ?
http://www.youtube.com/watch?v=CiSVnNtffiI

94EG8

That hose is for the firewall MAP sensor you aren't using, simply leave it hanging.

Did you bleed the coolant yet?

mischka89

I put a half of liter coolant, and the noise of the motor disappeared. thanks

I have taken the b16a2 fuel rail, because the b18c doesn´t fit with the original fuelhose, is that a problem, what do you think?

94EG8

As long as it fits ok and it runs ok it should be fine.

mischka89

its me again, with the same problem. after I let my motor get´s hot, I saw the same expiration as yesterday. Watch the video and than you can understand me...

also the rms- needle doesn´t moving under 1000rms, although the motor is warm

http://www.youtube.com/watch?v=WwFO82y9Qug

or look at this, this happens after I start erngine when the motor is hot (after cooling fan starts), the needle is jumping around:
http://www.youtube.com/watch?v=9AoJ3m9khlY

is something wrong with the IACV?

94EG8

Looks like there's either still air in the cooling system, or the IACV is dirty. I'd try bleeding the coolant again first. Put the on a hill with the front end point up, take the rad cap off and let it idle till the fan kicks on. If that doesn't work I would take the IACV off and clean it with some brake cleaner.

mischka89

I have cleaned the IACV, but it still making "chainsaw" noise for ~15sec after I start engine. is it a normal activity?
you can hear the noise in this video: http://www.youtube.com/watch?v=9AoJ3...yer_embedded#!

94EG8

No it shouldn't be fluctuating like that.

EJeff8

^Did you bleed the system to ensure there are no air bubbles in the coolant system?
