Contactless throttle position sensor 34370022 for VW, Audi, Peugeot,Fiat, Citroen, Lancia


Once you will install this TPS on your vehicle, you will get:

-Increased reliability of throttle
-Stable idle speed
-Accurately and precisely throttle response
-Fuel economy
Also you will forever forget about  Bosch’s and chinese  copy sensor’s track wear, because our sensor doesen’t have any wearing parts.

Hello folks !
I have designed this kit  to replace 4-pin( manual transaxle) and 7-pin( automatic transaxle)
Throttle Position Sensors

  • Bosch 3437022
  • Bosch 3 437 022
  • Bosch 3 437 022 512
  • Bosch 3 437 022 900
  • And their analogues

which was factory installed on Mono Motronic and Mono Jetronic systems on 1980-199X VW, AUDI, Fiat, Citroen, Peugeot, Lancia etc.

And this contactless TPS does not deteriorate like Bosh’s TPS

Here you can see Bosh’s TPS  track deterioration  over the years

Also this contactless TPS  will perfectly works on  a throttle with a damaged or broken brushes like this


Ohh! Man, are you kidding me?
How it could be possible and how it could work without contact-brushes?

This was  a first questions of one of mine friend , when he saw my new TPS at first time.

No, i am not kidding! 🙂
Contactless sensor is real, all we need is to install bushing with magnet on throttle spindle.

The principle of operation of this TPS Converter is based on measuring the angular position of the magnetic field of the magnet which is mounted on the throttle shaft.
Onboard Hall sensor measures the rotation of the magnetic field (and accordingly the rotation of the throttle axis) in space in degrees and transmits this value to the MCU which converts the measured value of the throttle angle into an electrical signals.
The characteristics of this signals are absolutely identical to the signals of the Bosch sensor 3 437 022.
It has onboard protection from overvoltage, reverse polarity and short circuits.

There are no difficulties with installation and everything is quite simple.
Here is an example of installation on bottom part of MonoMotronic injection unit

How can i tune it?

You can use bluetooth module to calibrate, tune and diagnose  it with a special software
(for more details look at  Complete installation manual tab upper)

Complete video tutorial

The main problem of tuning genuine Bosh or chinese tps is to tune it properly.
You culdn’t rotate it by hands precisely.

With “TPS tuner” software you can tune  this TPS precisely and you dont need to rotate it by hands phisically.

Just press calibration button to setup initial position and move slider to virtualy rotate TPS. You can virtualy rotate it in resolution of 0.1 of degrees, you culdn’t achieve this resolution if you will rotate TPS by your hands.

Order  contactless 3437022 TPS right now and forget about the tracks wear forever.
If you have any additional questions, doubts or suggestions please write a comment in the “discussion” tab 🙂

P.S. Also  we can develop similar contactless sensors for other brands of cars and motorcycles.
Proposals on this issue should be sent to the support team ( see e-mail at  the bottom of “How to order” page).

Complete installation manual

Installation of the new TPS on the throttle body
Here is a simplified video tutorial about installation of this sensor

Pinout of TPS and wires connection

Here is  a pinout :
1– Output  signal as  track #1 on genuine TPS
2– Output signal as  track #2 on genuine TPS
AT-Output signal for automatic transaxle ECU
O2/REF – Input signal   of reference voltage 5V or oxygen sensor signal ( for test )
GND – ground
12V – supply voltage

Ok. Now lets look at the connection diagrams

On the schematic above you can see TPS with blue wago type connector, dont worry about it  – it was on previous version. But for clear  connection view  this  picture will be the best, because pinout is same .

Ok . Depending on transaxle type , there culd be  two  differet TPS connectors  and  corresponding connection diagrams( see pic above).
To find  numeration of pins of   genuine connector all you need is  to turn inginion on and find reference voltage(5v) with a multimeter.
Nothing difficult.
If you have questions – feel free to ask in  discussion tab.

For supply voltage we need additional wire 12V .
As 12V not presents on genuine connector, we can take it directly form battery’s positive terminal via fuse 1-3A ( not included in kit – you can buy it at any local autoparts store). The fuse should be installed as close as possible to the battery to protect TPS’s supply line properly.

To connect new connector to vehicle wiring you can use:
-Butt connecor like this

-scotchlok splices like this

-or soldering

 You can cut genuine TPS connector from vehicle’s wiring and install new one included in kit. And from other new one and  old genuine connector you can make an adapter for genuine TPS  and with  this solution you can connect  both TPSs to  vehicle wiring as you wish and as you need.

How to install  a bluetooth module in the socket of the sensor

During installtion please check marking on bluetooth and tps:
5v-5v, gnd-gnd, rx-tx,tx-rx

Tuning Software for Android and Windows
You can download it  from this link

Precision Tuning

Also you can  very precisely tune the TPS  and it will work exactly as the manufacturer of your car conceived.
Before you  will make  this , you should check:
1. Oxygen sensor. It must be 100% working.
2. Rubber mounting of the throttle body. It must be not damaged and there must be no vacuum leaks.
3. Intake air warmup system should be working and intake air temperature should be in a range of 30-40 Celsius degrees

If all above checked and works perfectly, run VAG COM , VAG Tool or Monoscan software, reset adaptations of ECU ( on some models you need just disconnect battery terminal for a couple minutes).
Now start engine and drive your vehicle for a couple kilometers and check mixture correction( or Long term fuel trim).
Mixture correction should be +/-8% in ideal. If it is out of range, then virtualy rotate the TPS to enrich or enlean a mixture (0.5-1 degrees is enough and don’t forget to store virtual angle to EEPROM of TPS), drive a couple of kilometers and check again -make corrections if needed while mixture correction not achieve +/-8% range.
Also you can make this tuning at stopped vehicle at 3000 rpm, but in this case you will need to wait  at this RPM (3-5 min)  while ECU learns a new mixture correction.
Thats all! Enjoy how it works 🙂

p.s. After all tunings done it will be good to remove bluetooth module and apply an automotive sealant on the connector  to protect it from moisture.

Technical Characteristics

Anton’s TPS has an onboard  protection from  reverse polarity and overvoltage
Supply voltage 6-16V
Operating temterature range -40 to +110 С
Neodum Magnet H class (operating temperature up to  +120С)
Autotunig and firmware update functions provides you simple installation, tuning and upgrade is  nessesary
The PCB  of our converter  is varnished to protect it from moisture and reagents


1. Why there is a difference in the  diameter of available  bushing with magnet , and which one should i order?

It is very simple  –   it depends  on  engine’s volume , because  there installed different throttle bodies.

Engines with displacement 1.8 and 2.0 liters has throttle body with a throttle spindle diameter 5mm:

And engines with displacement 1.4 and 1.6 liters has throttle body with a throttle spindle diameter 8mm:

To make right choice you need to know your engine displacement, or remove genuine TPS and check throttle spindle diameter 🙂

2.  What if spindle brushing  is totally damaged? As your TPS is contactless, I wonder whether it was functioning to my damaged spindle.

In  this case our TPS will perfectly works. See pictures above  with damaged brushing –  now it is not a problem at all.

3.Where can I download a tuning software?
Here is a download link

Hi Anton! I have an old Fiat Bravo I 1.4 with regular TPS problems. My qeustion is that your contactless product could be compatible with it? It has an older 4 pin TPS wich has a 5 V supply voltage from the ECU, not 12 V as the newer ones. Does your product work with 5 V supply power?

1 year 9 months ago

Hello, The sensor is universal. For manual transmission you dont need to connect AT output of the sensor.
5 v is not a supply voltage!- it is reference.
For supply of the sensor need additional separate wire – you need to make it by your own.
To understand how all works look at manual tab and connection diagrams.

I have a PSA engine (KDY – TU3M) at a Peugeot 106 (11/1992). The management system is a BOSCH MONO JETRONIC A2.2
As the tps are in poor condition i decided to change the factory pts with yours contact less product, but first I have something to ask:

1. The file does not open at win10 or android with winrar or iso or breezip. It is also not in the Google play store for installation on Android.
2. Will the proposed setup in your video with contact less TPS, the idle motor will be able to work properly, even if the throttle stop bolt has been setup in the past? Do you have anything extra to suggest as a setting in this case?
4. Is there any more availability of a contact less TPS?

2. I don’t no why i must have at pins 1 & 2 about 0.19mV (0.17 – 0.20mV & not 0.17V as usual) for about 700mV from λ. for work properly with my bad PSA official TPS??? [ From 15:55 ]

2 years 25 days ago

Any value ok , the only one thing which matters- λ voltage when you setting the TPS on working engine.
Also before you beging precise tuning λ must be disconnected from ecu and battery must be disconneced for 30-60 second with a pressed brajke pedal ( bulbs discharges ecu circuits) to reset mixture adaptations.

Hello Dear Developer,

I would like to order one for my Audi 80 1.8S engine code: PM. I have Samsung S7 Edge. Is this android application still works ? I want to fine tune my carburetor and this seems to be a perfect solution. Please let me know so I can put an order and try your invention 🙂

Thx in advance !

3 years 14 days ago

We are not tested it on Smsung s7 edge and at this moment we are rebuilding android software.

But if it will not work on your smartphone, you can use windows version – it is tested and stable.
Also the softwre works only with our contactless sensor and it compatible with mono motronic and mono jetronic fuel injection systems.
It is not comp[atible with carburators like solex or pierburg etc.

Buongiorno…sono un meccanico in Italia dovrei riparare una fiat panda 4×4 1100..con iniezione Bosch potenziometro con 4 PIN diametro boccola 5mm e compatibile anche per questa vettura?

3 years 28 days ago

Yes – it is compatible with fiat panda.
But before will make an order you need to romove genuine TPS and check axis end diameter. Some models has 5mm axis end, other 8mm.

Google translate:
Ciao. Sì, è compatibile con fiat panda. Ma prima di effettuare un ordine è necessario rimuovere il TPS originale e controllare il diametro dell’estremità dell’asse. Alcuni modelli hanno assi da 5 mm e altri da 8 mm.

Hello, did you teceived my question below? I need to buy this contactless position sensor for my Citroen ZX 1994 but my engine is 1.4 and the axis is only 5 mm; will it fit my car? Best regards

4 years 8 months ago

Sorry for delay with answer.
I checked your car in autodata database. And it seems that there is a bosch monomotronic injection system.
This sensor will perfectly work on this system.
I am wondered a little bit about an axis diameter. Because on VW, Audi and Peugeot there is a 8mm axis on 1.4-1.6l engines.
The outut characteristics of the sensor on all engines is the same. So you need only to choose right bushing.
If you meaured throttle’s end diameter 5mm, then choose 5mm bushing. Or i can put both in the package.
Also remember that this sensor supports dataloging and firmware update, so we can remotle create any output characteristics.
Within several days i will post an update here , becausde we made new tuning software for this sensor for Android and Win platforms.
If you have any additional questions – feel free to ask.
Best Regrads
