Fuel/o2 Sensors Options

[Eydfinn]

Hi there...

Can any one tell me, how many fuel/o2 sensors my mitsubishi carisma 2002 1,9 Di-D hatcback has.
I can see there is one on the air intake, i havent seen any others, so plzz help if you know.

and can any one tell my if this car has a OBD II system, or what system it has.

Anyway i´m am new here this is my first post.

thanks far all the good info on this forum.

Is there any issue yu are having? Well there is the Air meter , Intake Air Temperature sensor , Barometric Pressure sensor , HO2S before and after catalytic converter

ok thanks, i don´t have any problems with the sensor.

i just want to know, i´m experimenting with hho, so i need to manipulate the fuel injection.
so i have set an efie to the o2/maf sensor if i have more than one sensor i need to control them to.

But i have a problem with my turbo charger, so my car is not running so well right now, so i don´t see the changes, when i try to mulate the fuel injection,

i think it is the egr valve, or something with the vacuum, but i don´t know how to locate the problem.

Most things , wid a Diesel , yu can manipulate the IAT and get sum extra power and TQ if dun correctly. Manipulating the IAT signal is the easiest and works wonders . Trying to maniplulate the MAF and its signal will futile and cause many issues , altho manipulating the barometric pressure sensors signal/output voltage signal will also work to a benefit . As most Piggy back performance systems on DiD focus on inverting and manipulation these 2 main sensors versus directly interupting the injection harness all the time. Thus this and the charge air recirculation valve and wastegate.

If attempting to manipulate injection wiring as many petrol engines , there is a positive in voltage to the injectors , as with diesels and the computer sends a varied grounding voltage to the injectors to make a weak spray or pule. Altering this ground voltage and rate will provide a better spray.

Thanks for the replay (IMG:style_emoticons/default/smile.gif)

You seam to know alot about cars.

but what I need to do is, decrease the injection by telling the maf sensor there is not so mutch air, so don´t inject so mutch disel.

My maf has 6 wire, and i need manipulate the wire going to the fuel pump.
in the maf there are 2 low voltage wire, i´m in doubt wich one goes to the fuel pump.

Do you know what kind of computer system this cars have?
