A610 TPS ( THROTTLE POSITION SENSOR ) READING PLEASE

[phildini]

.........`Now 255 = 5V, hence (10/255) x 5 = 0.19Vdc, so 0.15 to 0.18Vdc should be ok.............................

Red 5.05v, brown 0.013v, blue 0.190v all colours refer to the loom not tps side.
Hope this helps, all measured ignition on, engine stopped, throttle shut.

John would not forgive me if I didn't say put some heat shielding on too if you can.Lee

Thanks Mr Faulks thats all I wanted to know...... I have set my TPS by Lee's figure 0.19v but when I plug the Diagnostic machine it tells me it's 0.05V.....

We are going around in circles guys.....what we do not know is what reference Lee was using for his readings......also which lead you were attached to when you set it to 0.19v....and when you set that figure, what was the voltages on the other two wires, were they the same as Lee`s.
Also.... if you are not using the XR25, how do you know what the voltage 0.05v refers to?

Agree John.

Phil, did you check WOT readings, at the end of the day, they are equally important if not more, as this drives airflow / load enrichment algorithms. Difference with a turbo motor to n/a you can essentially maintain the same manifold pressure with varying throttle angle and hence change the AFR the engine sees if MAP is the only input reference (read GTA). So WOT in my book is more important than idle position provided the engine picks up and responds correctly off idle.

I use the Diagnostic machine and there is a specific setting for the TPS, which reads the 0.05v.but I don't know where the machine gets it's figures from. My TPS was adjusted to Lee's figures and using the same wires.

I guess I will need to do a test with multimeter together with the diagnostic machine.

I spoke to somebody who works for Renault down the road and even though they have chucked the XR25 in the bin, he did point out that the 610 setting is very sensitive and not as forgiving as the R19, Clio16v etc.... of the same era. In fact after I fitted the new TPS and drove it to Silverstone, I adjusted the TPS the same as my Quadra setting ( as the Quadra seems to have the same ramge as the 610 ) and it was drinking fuel, and the setting was only 0.26v…0.07v more than Lee’s reading.

I use the Diagnostic machine and there is a specific setting for the TPS, which reads the 0.05v.but I don't know where the machine gets it's figures from. .

Fillipo, the problem here is that the 610 manual does not give voltage values for adjusting the TPS.... it only gives reference numbers specific to the XR25, so using your Diagnostic machine will only cloud the issue.
Lets cut to the chase.....in the absence of the XR25, your original idea is really the only way forward...that is by comparison with another 610. Now we know Lee`s 610 is running OK, and he has kindly given you some figures from his. Now I think we can assume Lee`s reference point was Earth (engine body) so..... if it is possible to replicate his figures on all three wires by adjustment of your TPS then that is the best you are going to achieve without the XR25. Don`t expect the readings to be exactly the same, remember Lee`s TPS is some 18 yrs old possibly, and age does affect values.....just get as close as possible.
A little tip.....your TPS is new and the insulation is good.....stick three pins into the wires so they make contact with the conductors.....make sure they are spaced so they cannot touch, .... now you can touch each of the wires in turn as you adjust the TPS ...hopefully you will find a spot where all three voltages fall into place as per Lee`s readings. I cannot see any other way of getting a reasonable setting without the use of the XR25.
The only thing to remember is that Lee`s readings were taken from the loom side of the connector....if you are going to use the wires on the TPS side, make a note of the colour change on any of the wires and compensate as necessary.
Good Luck.

Hi Folks,
I have been (am ) travelling so missed all this. Greetings all from Nice!- but as I'm stuck in a works chosen hotel 50 euro away from the nearest town, and car less, its more like a comfortable, warm prison with good food.

Just for clarity...I measured all voltages against the engine block as earth, engine not running, throttle untouched since I drove the car in a few days before.
I measured the signals by pushing multi meter probes into the loom side of the connector (hence the colours). The way its wired, this brings additional inaccuracy as the ECU to Engine may not be a perfect earth (but as the car runs fine I assume that it will be close). My car has the earth retrofit (Phildini yours doesn't BTW- I noticed last time I saw it).

I have the same Sykes diagnostic box as Phildini and when I get home I will see what it says the TPS setting is now as seen by the sykes box (Phildini what Renault pod version are you using?)

As far as I'm aware my car has its original TPS making it...17 years old last August- but as the wires aren't cracked (yet) it might be younger. Its at least pre 2004 when I bought the car.

Cheers
Lee

Accupunture on a GTA.. now i have seen everything.!!
