Hello
I found your advice to be finally fixed.
I drove yesterday, 14 km, with the probe plug disconnected.
No indicator lights on the dashboard.
The Audi Group obviously did not plan to light an indicator on the Skoda, Félicia special, from 1995…
When the lambda probe is disconnected, I found no difference in driving or engine noise compared to usual; I suppose there will be over-consumption; the computer does not receive a voltage from the probe, it must include 0 volts?
After many kms, the probe must be changed; if it is out of service (broken, because worn), what type of fault does it appear, then? (What were your symptoms
Former Oceano?) A colleague told me that it was slow hiccups; so it’s not the same behavior as when it’s unplugged. So a tension must be present, and can be the maximum, because the failures indicate a lack of gasoline, the calculator believing to see on its probe a mixture too rich.
Is this how it works?
You say that by electrically heating the probe, it is deceived (tricked), and begins to regulate by saving consumption?
If I unplug the probe (making only 5 km journeys), and after 1 km, I put XNUMX volt on the computer socket, do you think I would save fuel? but there would be faults, if the different parameters are not adequate (untranslatable
), and the engine is cold? Is it possible to do so? Is there a risk of imbalance or deterioration for the computer?
On the probe there are 3 wires; I suppose the -, the + 12v, and the return voltage from 0 to 1,1volt? is that how it works?
Thank you
