Hi,

First of all, í'm new here, so please don't flame an shoot me, i'm new into boosting.

Okay, here it goes:

I've turbocharged my D15, with a Garrett t3 turbo.
It runs great when there is minimum boost., no issues so far.

But, when i hit the gas, and my car revs up to like 4000rpm, the boost get's around, 4/5psi... then my engine check light pops on...

I've checked the error codes, and this are the results:

3 - MAP (afaik)
5 - MAP (afaik)
7 - TPS...

Now, the TPS is like strange... does a d15b2 have a TPS ? And, if it does, where the hell is that thing at?
I've found a sensor like thingy behind my chocke-throttlebody, but... i'm not sure if this is te TPS.

So, if anyone has suggestions 'bout that... pleaaaaaaaase.

Then, the 3 and 5 errors.
I've used several checkvalves... like 4 diffrent brands... some are from a gardenwarehouse, the others from a aquariumstore.... all... don't seem to fool my MAP sensor...

Or, is it possible it has something to do with the TPS error?

I mean, SandmanCivic is running almost the same setup as i am, and he has NO errorcodes.

as far as i can see the MAP error occures when i'm getting to 5psi @ 4500rpm in 2nd, or in 3th and 4th at 3000rpm.
I now have two checkvalves BEFORE the MAP sensor... but still... no happy boosting.

Please help me out here.

(btw, i want to by a ML002 from synapse, but it is hard to get one here, cuz im in The Netherlands).

Thx,
t0n

I had a code 3 and 5 before try switching up some vacumm lines to the map sensor i changed it and never had the code again, the tps sensor is on the right side of the manifold U can see it under the big cover. the sensor could be going bad. check the vacum lines because you might not be having anof vacum going to the map sensor check this stuff out and let us know if it still occurs

t0n

Thx for the reply.

So, you are sure that there is a TPS on my B2 (dualpoint) intake?

And about the vac lines to the MAP sensor... What is the best thing to do, intake -> checkvalve > checkvale > MAP ?
Do you suggest to use a longer vacuumline towards the MAPsensor? so that the checkvalves can get rid of the overflow first?

Jimclure

Yes iam positive of the tps sensor on the B2 I have the same motor. what is your vac that you have at this time. Shouls be around 18-23 to have max vac i dont know the check valve question because I havent used it. Is your lines ran like you have it as you said intake, check, check, map. If so try it and some other ways its a trial and error basically at this point. others here will be able to tell you more info on the checkvales so give them some time.

Yes the D15b2 does has a TPS, its right under the TB, *SEE PIC BELOW
its held in by a rivet, that you can cut a notch in a turn out, or you can just drill it out.

its the unit that looks like a green plastic button

heres a shitty pic.



hope this helps!

Okay, now i know where it is.

But, what doe I need to do with it? Or is it just broken orso?

t0n

To get back on the MAP issues.

Somebody offered me a 3BAR mapsensor... is this wise to buy and install to get rid of my map issues?

Jimclure

You wont need your check valves anymore if u get that how much is he selling it for?

t0n

You think?

This map sensor, accepts 3Bar, but... it still sends a signal out to my ECU, wich does not understand pressure.... right?

He's selling it for €60, that's about $75

Your ECU Doesn't know what boost is.
I would try with some checkvalves.
Just like Jimclure said, basically trail and error.

PS
Is dit die rooie civic van Honda Team Nijmegen?
