How to Replace the Lambda Sensor on the Sym Fiddle?

Model: Sym Fiddle
Part: Checks and maintenance

Video tutorial

To replace the lambda sensor on the Sym Fiddle, loosen the screws securing the panel in the centre of the footwell of the bike: once these screws are loosened, you can completely detach this panel, allowing you to proceed to remove the one at the rear.

Under this last panel, you will find the lambda sensor, which must be pulled out of its housing and disconnected from the corresponding cable; at this point, you can insert the new one, ensuring everything is functioning.

Finally, cover everything by reattaching the panels.
