I need to replace my lambda sensor on my 2016 Turismo Veloce Lusso but have run into the usual problem of not wishing to pay dealer prices!

I've looked through loads of auto parts websites and am none the wiser which type may be suitable.

There are no marking at all on my sensor, although I can see it has a 14mm thread and the four pin plug by Delphi.

Has anyone found success with a cheaper equivalent sensor?

The normal narrow band O2 sensors are pretty generic. Only the plug and length of wiring varies. Pick one and give it a try. They all work on the same principal and signal. 4 wires are heated sensors (most common).

Thanks for the heads up. I've now sourced a used sensor, but at least it'll have the right connector as it's from a similar MV.

Looking at the old one it must have taken a knock at some point as it's not straight, but slightly angled - any tips for removing it as it looks like there's not enough clearance with the engine when being removed?

I don't have a TV parts list, but on both the F3 and the B3 the sensor is located on the exhaust header where the three pipes come together. It may be beneficial to drop the exhaust header to access the lambda sensor...although that shouldn't be required as it is a normal maintenance item.

I managed to remove mine easily without dropping the header - on a Stradale but should be pretty much identical configuration.

F3 800 did not need header dropped to replace sensor. Connector was on left side of bike so plastic cover on that side was removed.

What typically caused the sensor to fail?

 

[esq'z me]

They can be damaged by excessively rich mixture or physical damage. Normal failures are in the heating element, but it is a wear item (though few bikes get enough miles to see that).

You can get a replacement sensor, try your local Bosch dealer ?

Try NTK sensors......
They make most of them......
All you need is the correct thread and number of wires
:wink2:

Just in case anyone reads this thread and has a similar problem.. in the USA the emissions system which includes the Lambda sensor is covered under warranty for 5 years or 30,000 kilometres. I just had mine fail and have one on the way under warranty.
