If you run into problems with your VSS or somebody else wants this info I can make a circuit diagram to upload with all the necessary components.

The only other CELs I get on mine are thing like fuel tank pressure and temperature. If these are the same ones you're getting, they're very easy to trick. Below is info for correcting the two codes I got. I didn't actually go through with this to get rid of the codes because I'm not running a CEL, I just scan it if I notice a problem.

183. The fuel temp info to ecm is wrong. It's expecting to see 4.71v or less. That should be easy to fix, just send 5v thru resistor to that ECM wire. You may have some other sensor that provides the right voltage. Just jump it to that terminal.

463. Fuel level sensor. It expects more than 10.9v with ignition on, around 3v when running. That should be easy fix. See if your current fuel sender provides 3 vdc. Then send that voltage to ecm.

Let me know if you are getting other codes and I may be able to help

Thanks Mike, that's great info! Exactly what I am looking for !.
I'm not running a second O2 sensor, so I somehow need to trick it into thinking that one's there as well.

Hey quys..

Do you think one of those might be work to solve my problem??
I have found from a local shop called "Brantz rallymeters"these two sensors

Which of them is the correct one??

Universal speedcable sensor



or this
Japanesse Gearbox




Price each is 50euros.

Thanks in advance,
Jim

Hey Jim,
Check out my previous posts, and if you want those Speed sensors to work, you just need to check the output if you want the computer to actually know the correct speed you are going. The ecu is expecting to see a square wave pulse, with four pulses per revolution of the wheel. The computer considers one pulse to be voltage decreasing to 0V (below 0.1V or something) and increasing to 5V (over 4.7V I think). So if the speed sensor you find outputs a wave you just need to supply it with a ground and 5V from one of the engine sensor power wires and you're all set.

Don't worry about the 02 sensor, no tricking needed. Just run the first one. The ecu only uses the first one in closed loop operation, the second one is sort of a 'check' on the Cat Converter, but it doesn't affect how the engine runs. On my van I hooked the second one up but it just sits exposed to fresh air, haven't had a code yet.

Hi

Im glad you told us that, I only got the one 02 sensor with my motor, just before the turbo and I was going to source one, no need now.

Thanks in advance all of you quys!!!!!!!!!!!
The problem was solved after installed the Brantz vss behind the speedometer.
Now it revs with no problem at top high of 6500rpms and is ready for daily use and why not for some street race!!!!

Kind regards,
Jim

Please take it to the track
No Street racing
save that for the Rice burners

It seems that i will never pass the VSS problem

It stops to give signal in to the ECU..

Can i bypass the error code and if yes how can i do it?

Also until now no way found on how to read from my 14pin OBD..as I need to plug a paraller ECU

Please see attached pictures and if anyone knows anything about this problem please advice.

The OBD slot appears with read color.





Thanks in advance fellas!
Jim

What are you using to read the OBD codes ?
I bought a cable of a guy in Montreal and used a free tool to read the codes (I think it was EcuExplorer)



As to the VSS, I used a super simple solution, and it seems to work fine. Is your ECU not registering the signal, or is your VSS not sending out a signal ?
