lambda dead?

I've finally managed to get my tuscan talking to the laptop so quickly checked things out and lambda 456 is showing a constant 0 volts. It also shows as ok. With the car running the adaptive are well into the 30.

123 flicks between 0 and 1 volts generally around 0.8 and the adaptive around -2 to -4. Only had it running briefly so was cold but does that indicate lambda 456 is dead?

Checked the connections again earlier and all seems ok there. Will pick a new one up from Racing Green tomorrow. Looks like it's a bit of a PITA to get to it without removing the battery etc.

Will find out later in the week when i go to change it over.

Changed the lambda at the weekend.....now running MUCH better, smoother idle and better across the rev range, as expected really.

Does now show up the shunting on light throttle so probably put the throttle body bearing mod on the list for winter.
