Closed Loop

I have an early G1 running a Commodore V6, it has the option to turn Lambda on or off using the hand controller, I have a brand new sensor fitted but on the hand controller screen where it displays injector duty cycle and Lambda reading, it always sits on 0, it is wired to the ECU correctly, tested that today. Any ideas?

You will need to check you are getting a voltage from the sensor. You can check with a volt meter it should read around 0.8Vs with engine running Also check the sensor has a very good earth back to the block.
