I would like to know the Lambda Sensor signal voltage range of MINI SPi in both sensors (sensor near catalyst and near the manifold)

The SPI only has one Lambda Sensor. And off the top of my head i think its a range between 0V and 5V.

Mine has 2 sensors. The sensor it has near the Catalyst is no longer there now. So, i just wanted to send a false signal thru the wire to stop the warning buzzer.

No Can Do, If it is indeed a Lambda sensor it needs to be there, there is no other way of generating a changing voltage.

(In case anyone finds this in future)
The 2nd sensor, if it is AFTER the cat (and to do with the buzzer like he says) is a temperature sensor
There was one fitted to my Jap spec Cooper
I think it's totally separate from the ECU and just connected to a buzzer in case of very high temperatures
The buzzer shouldn't go off if you keep the sensor connected to the end of the wire and remove it from the exhaust
If the sensor has died then not sure what resistance it is expecting sorry..
