Hi Spikes
Cool nice pics, it seems that your intake manifold is different to the carb models.
What fits onto the throttle body? the air cleaner box?

Hi Ari Yes, with the air cleaner in place it looks similar to the normal 1700 crb model as you cannot see the manifold. It is a std round LN air cleaner Spikes

Hi Spikes
Thanks for the pics - this is the first time I see what it actually looks like.
One of the questions I was thinking of asking Ventz Lazarov yesterday was whether he knows how to work on Ladas which have been fitted with these injection systems - probably a very stupid question I think.
Well, I forgot to ask the question - but I am more than convinced that Ventz should have all the answers we are looking for.........
Regards
Danie

Hi Guys.
I have been battling with the ECU and fuel injection system for a year now.
I have replaced most of the sensors on the engine but the check engine light remained on.
Today I have some good news for any other 1.7i owners.
Jorge Auto Electricians in Krugersdorp have the right equipment to diagnose and repair our TBI systems.
They instantly recognized the components and was able to diagnose that the Throttle Position Sensor was of the incorrect type.
They were even able to source one that could be in the country within 48 hours. Thankfully Ventz has one at about half the price.
As my father always said: you get mechanics and new-parts-fitters. These guys are still very much mechanics.
You can find Jorge Bonifacio at 57 Kerk street in central Krugersdorp. Tel 011 665 1814.
I will report back once the TPS has been fitted.
Regards
Spencer

Spencer, how did he recognize the TPS as an incorrect one? A faulty TPS would translate in very bad driving at steady speed and bad acceleration. Do you experience one of these things? What fault code do you read?

Yes,we have all of those symptoms. The fault codes are only for the tps and lambda sensor.
The tps that was fitted articulates in the wrong direction. The Generic one I fitted did the same thing. It therefore gives a full closed reading when you accelerate. This confuses the hell out of the ecu when it gets readings from the exhaust manifold sensor.
But it still kept going all this time being driven everyday.

That explains why I can go faster in reverse than in forward gear ;D ;D ;D
Where is this monster located and how did you(they) determine it was signalling the wrong way. Can I inspect it myself?

Spikes you would be able to measure it yourself with a multimeter. On most cars the reading should be about 0.5v closed and 4.5v at full throttle. I will look it up in the manual tonight and give a better explanation.

Hi Spikes
It is located on the firewall side of the throttle body. It has a wire running to it. Directly opposite the throttle cable cam. The throttle shaft runs through and turns the tps to give the ecu a reading of where the vane is and how much fuel is required.
Mine is slightly open in what is supposed to be the closed position. As the accelerator is pressed, it then loses all tension and does not move with the throttle shaft. The tps then goes completely closed as the throttle opens.
Calla is correct to test the circuit and resistance, but this is what I have been doing all along. Nothing wrong with the TPS in that regard, it just gives the incorrect mechanical interpretation.
Imagine going to China and only speaking Afrikaans. Lots of fun, but ultimately there is no communication. Or like getting married....
Any way, the generic opel tps from goldwagen reads in the wrong direction.
They started checking the mechanical part of the equation because the electrics checked out, the ecu checked out but the reading from the tps continued to flag a code.
Regards Spencer
Hope that makes more sense.

Hi Spikes
I had a good look at the manual and the tps on the Niva has no adjustment on it. They also do not give any voltage reading. I will search the net when I have time.

Hi Spencer & Calla Thanks for the info! At the moment our NIVA has no ECU fault codes. I was just curious about the diagnostics and the physical location of the TPS. spencer and other owners of the TBI models. I have a pdf version of handbook on the Engine Management System. PM your e-mail address and I'll forward it. I think I found it on Baxter's site way back Regards Spikes

Hi Spikes.
Thanx, but i have that document. It was one of turbo nutters writings. It did help me in understanding the tbi, but i still fitted the wrong part. No meds available for my condition, I'm afraid.

Hi Guys.
Wow, what a difference a working TPS makes!!!!
Kalashnikov drives like a dream. No more jerking and stalling. No more idling at 2500rpm.
The check engine light still comes on and goes off periodically, but I think the ECU just has to start believing the feedback from all the sensors....
Regards Spencer

Hi. I am looking for a injection manifold for my lada. wil it fit on the carb head? Modified my carb intake to injection and it looks very bad. Also not shure if it works as well as it could. Thanks all the helpfull advice so far. Regards Ruan

Darrel found a replacement high pressure fuel pump for the 1.7i NIVA Here are the details as supplied by Darrel: " On the pump there is an electrical connection where the standard wiring plugs into, providing 12V to the pump. The Corsa’s pump has a different connection than the Lada’s pump. All I did was to cut the two wires from the Lada’s connector and re-connect the two wires to the new Corsa connector (which is supplied with the pump) and then connecting it to the new pump. The filter bag at the bottom of the Corsa pump is slightly bigger than the Lada filter and does not fit snugly to the pump inlet. I used a high quality jubilee clamp to secure the filter bag to the pump inlet. Just a note, take care not to pinch the wires between the pump body and the fuel tank body when replacing the pump, which I did the 1st time and then the fuel tank gauge shows that you have a full tank! I have not measured the pressure yet but the Lada runs much better and the fuel starvation is 99% gone."
Darrel will supply the pump part number which will be incorporated into the "After Market Spares list"
Thanks for the info, Darrel.

Hi, Changed spark plugs last night and seems one (or more) of them were faulty and ended-up flooding the engine (or at least I hope that is the problem). Started it after change, ran beautifully, started later, ran for 1 sec and then died. Will try to sort it out tonight. Read somewhere that fuel injected engines switch off the fuel pump when you push the pedal to the floor. Can anyone confirm whether its the same for the Lada 1.7i? Would be useful to un-flood engine. Thanks, Koos

Pull the fuel pump fuse (no 1 according to the manual).p 188 volume 3 of manual. There is no cut out on the pedal mechanism. It may be the case with "drive by wire" throttle mechanisms.

Hi Koos do you have the TBI specific manual? I can send on to your e-mail if you don/t have. About 4Mb
