Probes and sensors
The use of probes and sensors are for measuring certain characteristics of your car and transmitting them accordingly. You get error messages, for instance. But since probes and sensors are wear parts, they ought to be checked at regular intervals and replaced, if necessary, so that they don't supply false information and cause real damage.
In our shop, you´ll find a broad range of different sensors and probes, which you can buy online. For example:
- air/fuel probes
- rail pressure sensors
- boost sensors
- low-pressure sensors
Air/fuel probes
The air/fuel probe is used to measure the residual oxygen concentration in the exhaust gas and transmit the result to the engine control unit, which ensures the optimum composition of the mix. The air/fuel probe plays an important role in protecting the environment. We have Bosch air/fuel probes for various engines, e.g.:
Please always specify your engine code when ordering since the number of different connectors is huge!
Rail pressure sensors
Rail pressure sensors make the engine in your car work smoothly and ensure optimum pressure conditions. They transmit the value of the rail pressure to the control unit, which in turn controls the pressure regulator. The injection system needs a stable rail pressure to function optimally, so the sensor should be replaced in case of a defect. In our shop, you will get sensors for different engines, for example 2.5L TSFI as in the Audi RS3 or the upgrade for 2.0L TFSI from Bosch, which is indispensable for performances over 139 bar.
Boost and low-pressure sensors
You get boost sensors and low-pressure sensors in the BAR-TEK online shop as well. We have boost sensors as a kit for 2.5L TFSI engines, for instance. This kit includes two map sensors, one in the front and the other after the throttle valve. Please bear in mind that the map must be adapted to the sensor.
The low pressure sensor also ought to be replaced in order to keep the fuel pressure stable and not to affect the running of the engine negatively. We have Bosch low-pressure sensors for different engines. In order to fit the sensor to the high-pressure pump and it must be done for tuning inlet manifolds – you need the right adapter.
