Andykid456 · #1 08-09-2007, 12:12 AM

Hey whats up guys my car which is a 95 gsx eclipse has been running like shit for a while so i decide to hook it up to and ecu scanner and get some reading here are the readings po120 which reads petal postion sensor (circite malfucnction i reallly dont know where thats located and what to do another code which is p1500 which is idil contol and p1400 emission controls i dont know what i should change because emission controlls can de a lot from and 02 sensor to something else and my car is sucking up gas like i never seen before thanks for you time and help andrew can you please tell me what there codes are

Alright man, well i just checked the good ol chiltons manual out. P0120 is your Throttle position Sensor Malfunction. P1500 says Generator FR terminal malfunction. (I honestly have no clue what that is) P1400 is a Manifold differnetial pressure sensor circuit malfunction.

Well the TPS is right on the throttle body, so check that and make sure its connected, no obvious breaks in the wire. P1500 i really don't know what to tell you. I've had that P1400 code before and it doesn't seem to affect anything. Check all your vaccuum lines and make sure they're all hooked up. They can cause the car to run shitty if one has popped off.

Have you tryed clearing these codes and seeing if they come back? My GSX loves to spit out random emissions codes, then i clear them and they dont come back. But then again with having alot of my emissions stuff removed im surprised the light doesn't come on more than it does.

I also just thought of something kind of weird. Are you venting your Blow Off Valve? I did this a couple weeks ago just to see what kind of sound the 1G makes. It sounds cool as shit but the car ran very shitty and stalled out on me a couple times at the stop light. I did get a TPS malfunction and that MDPS malfunction, along with a couple other codes that you didn't mention that i forget. So, in closing i would say if you have taken the recirculation tube off that connects the UICP and the Intake pipe, put it back on, unless you do the proper modifications to support it.

Hey i have and after market blow off valve which is hks and it goes in to the open with no dump tube alls i know is my cas is sucking up gascan you give me some segestions thanks im so confused and how should i check the sensors thanks

You need to recirculate your bov. That could be causing some of your problems.

TalonEclipseMixGsx · #5 08-09-2007, 07:35 PM

Exactly, first things first. Recirculate that BOV, and see if that solves your problems. You will run rich without the recirculation tube, which could be causing bad gas mileage. An O2 sensor is usually the case, but without a code for that i would hold off. Especially since they are near $150 from the factory.

With the sensors, again, get that recirculation tube on. Like i said before, my TPS and MDPS both tripped the CEL when i took off the tube.

hey how can i put a dunp tube on it has no connector and i dont have the stock BOV so what can i do?

Thats the recirculation kit for it. I really don't know much about these BOV's. I'm still on the 1G.

Andykid456 · #8 08-10-2007, 12:48 AM

Hey im really thankful for your help i have a few more questions you wont hear that kool sound anymore lol with the dump hose on it and what is that going to do for me and where is the idil control valve located thats alot for your help i reallly appreciate it

TalonEclipseMixGsx · #9 08-10-2007, 01:23 AM

Haha yep. Say goodbye to that whooooosh sound, and hello to no CEL's and a good idle. I must say i was sad to see it go after that 1 hour of driving around town.

If you want it that bad you can get a GM MAF, and a Maf Translator. But i believe that is running up into the $300-400 dollar range.

Your IAC should be located on your throttle body.

Andykid456 · #10 08-11-2007, 08:05 PM

hey are you sure that recirculation kit should solve all be probablems i teplaced one of my o2 sensors im going to replace the other one soon i put a bosh universal 1 in it seens a lil better but im going to replace the by the cat soon thanks is there away to tell if there bad? by looking at it

TalonEclipseMixGsx · #11 08-11-2007, 09:51 PM

No im not 100% sure that will fix your problem. All i can do is tell you the problems that i had, and leave the descision making up to you. But, I know for sure if you are running an atmospheric BOV without the right mods, it will run rough, and get a couple codes. As far as the O2 sensors, if you're not getting a CEL for them, they should be fine. The front one is the only one you need to be worried about, since it's the one that affects your fuel mileage.

Hey i took some guy for a ride that knows about dsms and he said i have fuel cut off and i really dont know what would be causeing that can u give me some info and also and easy way to tune the car so it runs good because the idil sounds like it has cams

Andykid456 · #13 08-12-2007, 01:57 AM

Hey i took this guy for a ride that kinows alot about these cars he said i have fuel cut off and i i would like to know what can cause that and should i change the fuel filter and he also said it can be a boost leak which i really dont know how to test for im thinksing about putting a front mount with pipeing but i really dont spending much money on a front mount so whats a decent brand and can you please give me more info thanks for your rime

TalonEclipseMixGsx · #14 08-12-2007, 05:08 PM

Fuel cut is when the MAS sees more air than the ECU will allow therefor cutting spark and fuel to the engine, to prevent damage. If you're still on the stock t-25 i doubt its fuel cut unless you're running rediculous amounts of boost. As long as you keep it around 15 psi or so you should be fine. I also hear that it's like running into a brick wall. I've never experienced it, but don't get it confused with running rich at higher RPM's, and the car buckin like crazy and not accelerating.

It could be a boost leak. You can either buy a boost leak tester from slowboy http://www.slowboyracing.com/estore/...4&cat=0&page=1 for $30, or make your own http://www.vfaq.com/mods/ICtester.html for $5.

I got my FMIC from Extreme Turbo Systems. But, before you go purchasing one of those, first, make sure your stock side mount isn't leaking. The shitty stock UICP and LICP are rubber and prone to cracking as they get older too, so that's something else to look for when doing the boost leak test.

I doubt its your fuel filter, but you never know. If you haven't changed it for awhile i guess it couldnt hurt.

Also, there's no need to post two different threads, with the same question. Everybody searches new threads in the subforums, so if they have something to add they will.

What are all of the mods that you've got done to your car?

Andykid456 · #15 08-12-2007, 06:29 PM

Hey so theres nothing i can really do about fuel cut im changeing the whole intercooler set up to a front mount so im not even going to bother testing for leaks and do i need to put a front mount on im getting hard pipeing and intercooler i have a t25 turbo so hoow hould i run the hard pipine it just bends out on one side another thing im not really sure if i have a 6bolt or 7bole motor i brought not to long ago i just really wanted a dsm i was talking to the guy he said the motor blew and he had the top and bottem rebult i said why and he had a stupid look on his face the car only has 85000 miles on it but im guessing it should be a 6 bolt some one was saying the 6bolt has the crank angle sensor by the valve cover which i dont have but the after market parks i have it hsk blow off valve , Filter, act clutch 2100 w/ flywheel nothing big mani want to fix all my probbablems before i go big
