Lambda Sensor Installation
Yamaha Lambda Sensor
Suitable sensor mounting position is towards the rear of the exhaust , 2cm
to 10cm before the muffler. It is also possible to mount the sensor after the
junction of the 2 “Y” exhaust pipes, where they connect to the main single
exhaust pipe leading the rear muffler. In any case, mounting a lambda
sensor will require minor tunnel cutting to clear the sensor itself and the
wiring.
Ski-Doo Lambda Sensor (all model years)
Suitable sensor mounting position is easily found on the main exhaust pipe
that connects between exhaust manifold mounted on the cylinder head
and the muffler.
