Fiat Punto 2 1.2 16V Persistent Engine Light: Error P1135 and Viaken ECU Scan Usage

Hello.

I have a problem with Punto. The check engine light came on. After a few days, the indicator light went out and the engine was not on. But on unburned ignition it did not go out. After another couple of days it was on all the time.
I connected Viakena with fiat ecu scan and deleted error P1135. The effect is as follows. Before starting the car, the check engine is on and does not go out with the other controls. However, it does not light up while driving.
What does the persistent ignition check mean and is the probe in front of the catalyst to be replaced? Resistance is measured between 7 and 12 ohms.

This is normal. The check engine light is to be on after ignition and go out after firing. What was the description of this error? You can check the power supply of the probe heater, but if the error does not return, it will probably be ok. Between pin 4 and ground it should be 12V after ignition. There can be several reasons, for example, no contact in the plug, broken wire, short circuit or the probe itself.
