Ph1 to Ph2 Throttle Position Sensor Conversion

[KitsonRis]

I need to either splice a new throttle position sensor onto my Ph1 loom or swap the throttle position sensor from a Ph2 to my Ph1 loom. I am struggling to find a wiring diagram. Any help?

So I need to go from this Ph1 loom plug:

To this throttle position sensor:

I would prefer to use a Ph2 plug and not cut the brand new sensor. But if I go down that route of splicing it I will make sure there is a removable connection just in case.

There is method in my madness....apparently Ktec have updated the TPS in their ITB kit where previosuly it had an adapter cable to go from the loom to the supplied sensor. Now you don't need this. But being a Ph1 it doesn't quite work (by the looks of it I might be the first to hit this issue as it was new to them when I phoned them earlier!). Their solution was to get a Ph2 plug and use the new connector on the sensor or cut both plugs off and splice the loom to the sensor. I have asked them for a wiring diagram but just in case was seeing if anyone has any info. Have also posted in the wanted section for a Ph2 loom plug.

Ph2 tps is part of the fbw throttle body mate, and I’m pretty sure that it’s a female plug on the ph2 as well.

I just want to swap the loom plug for a Ph2 one to fit the new one Ktec have supplied. Their response was "The quickest solution is to cut the plug from your standard wiring loom and put in a Ph2 plug". So you are saying this can't be done? I just want to swap my top picture plug to whatever the Ph2 is so it can be plugged into the bottom picture.

I have most likely described what I am after very badly 🙃

Ah ok. I'm with you now! I may have one on a loom in the garage loft. Will have a look tomorrow.

@KitsonRis I looked in the garage loft, and I have a plug for the ph2 throttle body. However, it’s damaged and won’t stay connected. As you can see in the image:

However, there’s the part number clearly visible - explains why it’s broken as it’s an Audi item. Lol!

Part number is clearly seen in the image if you wanted to order one.

Thanks for taking a look, appreciate it. I’m tempted to just directly wire the loom to the sensor and make my own connector.

Do you know the wiring of the plug so I can cut mine about? Looks like there are more wires on the Ph2 plug.

Also KTec are trying to find a solution, have admitted it’s an oversight on their behalf as I did buy a Ph1 kit. However I have no idea what this will be!

I have a ph1 - ph2 wiring conversion somewhere mate. I’ll dig it out. 👍🏻

You are a saviour if you do!!!

Try this mate.

This is ph1 to gen90.

And this is the gen90 pin outs.

Credit for this goes to @barnesautos - I’m pretty sure it was him that sent me this. 👍🏻

 

[KitsonRis]

Amazing!
Looking at the bottom of the first spread sheet I just need to match the colours of the wires up….but my KTec TPS doesn’t have those colours (of course it doesn’t!!), it has green, red and black and not pink, grey and orange. Unless @barnesautos knows what the ph2 pin out on its TPS plug so I can work out what positions the colours are then I can map that to the Renault colours?

I do have a GEN90 ECU. I am hoping it will be a simple unplug the standard ECU, plug the GEN90 in and start it up 🤞

 

[barnesautos]

I do have the info you require , as I have been through exactly what you are going through.
I will get it and report back .

So this is what I’ve worked out your Ktec tps to be.
I cross references the connector with one I have used on mine.

What I would suggest is before going permanently, grab your multi meter and test the wire outputs from the ecu.
Measure 5v on the orange wire
Earth on the white wire and
Continuity the cream wire back to pin 43
Once confirmed , I’d connect the 5v and earth and then test the signal coming out when you operate the tps .
This can all be done on or off the bodies , up to you.

So below is the info

Pin 1 Green = Signal goes to Cream wire Pin 43 on GEN90 ecu
Pin 2 Red = 5volts goes to Orange wire Pin 71 on GEN90 ecu
Pin 6 Black = Negative goes to White wire Pin 87 on GEN90 ecu

I hope this helps.

PM me if you get stuck.

Amazing info thanks. I’ll try and get around to looking at this one evening this week or weekend.
I did look and according to the KTec website it is a P&G TPS as you suggested, although I forgot to look at the sensor itself.

 

[KitsonRis]

I’ve just checked what I was sent and it agrees with the Red to Orange but it says black to begin then green to white

I’ve done as per the instructions I was sent as tbh that was all the info I was given!! And the fact that the TPS I was sent would fit directly onto a Ph2 loom.

Have I been told bad information….again?!

 

[KitsonRis]

And this is the only marking I can see on the TPS (might be one in the other side but I’ll remove it when I get a chance to look at this later in the week)

 

[barnesautos]

Seems I have it different to Ktec
Do this first please check the signal wire only.
Easy way to find out is to continuity back to pin 43 on the ecu which is the signal wire , that pin has not changed its location at all so that is still the valid signal wire from tps . Note the colour beige or white , then go from there.

Tha gas the plan, work out where pin 43 goes. I presume when you say activate the throttle to test the signal that is just measure the voltage over the wire in pin 43 when I press the throttle pedal and it should read something? Electronics are not my forte!

Hoping to finish work a bit earlier tomorrow so I’ll have some light outside to see all this.

Hello everyone, digging up an old thread as i am considering buying a second hand KTR TB kit with Gen90 ECU currently remove from a ph2 to fit into a ph1. Did you manage to sort all of your woes?

Worth a read of Kit's project

Kit’s New Ph1 172

Keeping my eye on this, have looked at ITB's a few times just haven't gone for it, drove an ITB'd Ph1 a few years ago and it sounded epic, I am sure you won't be disappointed I wanted to do it to my old Ph1 and never got around to it. And when I bought this one I had to do it and I’m in a...

I ended up hard wiring my TPS into the loom (probably kit the best idea but I’ll get around to fitting a plug…probably). Turns out the newer TPS from KTec is for a Ph2 (as from what I was told by them their ITB kit essentially is) as the GEN90 is a Ph2 ECU hence all the pin changes required on the ECU loom plug to make it work in a Ph1. They admitted it was an oversight on their behalf and didn’t give Ph1’s a consideration when I went to fit my TPS and it wouldn’t work. Although it’s not the end of the world.

I used the table supplied from KTec for the pin outs on the TPS along with guidance from Barnesautos to make it work. I can try and dig out some details on what I did, might all be on my project thread
