 |
|
Hello. I instaled E85 convirsion kit on my Dodge ram 1500 (2004) V6 3,7. My OBD II gave me milfunction codes P0201, P0202, P0203, P0204, P0205 and P0206. And my RPM does not goes over 2300 on "P" and other position ot transmition. This unit works properly on all european auto and well tested on Nissan. Had someone same problem? Where should I dig? Should I modify my unit (have an opportunity). Sorry for my ugly english.

Do you have a link to the product you purchased?

Yes, I do. I have a link to production of this unit (it was well tested on european cars). But the producer can not understand where is the problem. So if You have a technical description of this problem - please, list it. Little description: my dodge starts, can drive, but the RPM does not goes over 2300 (falls from 2300 to 1900-2000 and againe rise to 2300) on any position ("P", "N", "D" and other) and allways light "check engine". OBD II gives P0201.... P0206 (even on GAS). |

Try looking at this reference it might help understand what is going on.
http://www.obd-codes.com/p0201
Sounds like a wiring issue or the converter is not giving the OBDII what it expects. It might be treating low impedance injectors as high impedance or the other way around.
See if there is a setting that allows you to tell the converter what sort of injectors you have, high impedance, and low impedance injectors use very different voltages and currents.

Thanks, but what is "impedance"? Can not translate ( I am from Ukraine). Resistance on my injectors is 15 Ohm. If I send on e-mail scheme of cercuit board of this unit (E85 converter), can someone answer where is the problem? |

Hello!
How can i know, is injectors on this car have common constant "+" and each injector controls by individual "-" from ECU, or they have constant common "-" and controls by individual "+" from ECU?
converter have built-in "emulator of injector" for ECU for 15 Ohm injectros.
it is usual resistiros, and usually it works, but i found in forums that there is some cars, that do not allow to use usual resistors - ECU needs "induction", and people have to make coils like in injector for emulation.
there is our ethanol conversion kit:

and ukrainian forum about ethanol fuel:

Impedance is the proper name for the combined effects of both resistance to electrical flow and the effects of inductance on electrical flow. For your purposes there are generally two different types of injectors.
The high impedance (high resistance) injectors need a different control circuit than the low impedance (low resistance) injectors.
Low impedance injectors usually have a resistance of around 2.5-3 ohms, and high impedance injectors have a resistance of around 12 ohms. IT sounds like you have high impedance injectors.
Each ECU looks for certain resistance levels, current flows and also watches internal temperatures of the driver circuits. If the injectors are demanding too much current from the ECU injector driver circuit, it can cause over heating of the electronic parts, or excessive voltage drop making the ECU think the injector is shorted.
I am not an expert on your specific injectors but it sounds like you have identified the problem. The ECU is not finding the proper resistance or inductance at the injector and is setting a trouble code to tell you something is wrong.
Hopefully someone else here has more experience solving this problem I have always used stock injectors my self so have never needed to correct this sort of problem.
Good luck!

Maybe there's something wrong when you use your conversion kit. I've never experience that kind of problem. Make sure that you did the right thing.
