i have cel code 3…
I’m planning to buy this one if it’s the right one. I don’t have a map sensor on my throttle body. Will this work?
running b18a1
18g greddy
obx r fuel rail
blox fpr
stock injectors and ecu
untuned
boosting at 6psi…cel 3 comes one for some reason…
Stock map should be good to 10 psi, if not 12, I don’t remember. I am boosting 6 psi and never got any problems with a MAP sensor CEL.
iono why…even though I’m boosting at 6 only. Throwing up cel 43 and 3…so i need a tune wtih 43 and 3…i need a map sensor but need to know if it’s the right one…
The item in that posting is not a map sensor. It is a missing link check valve. All that does is keep the ECU from seeing boost, and is usually combined with a FMU type setup or AFC hack. There is no way you should be setting off the MAP CEL unless the sensor itself is bad or it isnt hooked up correctly. Our map sensors are good to .8 bar positive pressure (11.76 PSI of boost), because they are 1.8 BAR absolute sensors. I run 10 PSI no problem all day long, so I would check the vacuum and electrical connections at the MAP sensor, then if they are good, get either a stock replacement (I have an extra if you need it, it is the whole assembly with the bracket and canisters and all), or a 2.5 or 3 BAR MAP sensor such as the GM 3 bar or Motorola 2.5 BAR from Xenocron. These latter options will allow you to run increased boost in the future if you so desire. And please for your motor’s sake get it tuned soon! At the very least get a chipped ECU with 450cc injectors and run a base map, that still is not a good solution, but is worlds better than running a turbo setup on stock injectors and a stock ECU.
damn…crazy, i guess i should check on it tomorrow and see what really is then…can the cel 3 go on before i slapped in turbo? my cel goes on before i slapped in turbo but every once in a while but never checked the cel till after i slapped in turbo.
trying to get it tuned but school exams are kicking in right now and i need time for school before i do anything else…i pretty much drive to schoo and back which takes like less than 10 mins…everything eles,go i just carpool…
Yeah, it could definately go off before a turbo is introduced into the equation. Think about this: the car was never designed/expected to have a turbo system on it. The MAP sensor code is there from the factory, so why would they put it in there if it couldn’t happen NA?
Anyways, I would check the vacuum lines running to the sensor, and the electrical plug on it to make sure it is clean and on there tightly. I would say that it is most likely a loose connection or something along those lines, but it is always possible that it could have failed. Check those, and if everything looks good, let me know if you want the MAP I have, and I can get that shipped to you pretty soon.
i’ll check on it right now…thanks for the help again…we’ll see once i check it…hopefully it the problem is what you said…vaccum and loose line…hopefully…but if all fails, i’ll get it from you probably in about two weeks…since im planning to get it tuned next week so im a little bit tight on money…
a stock ECU, Stock injectors on a turbo set-up= no good!!! did you ever fix the map problem or get a new map sensor?
think stock map was 10.2? Just get a GM 3 bar
