GS911 lambda sensor graph
« on: May 13, 2024, 10:21:28 AM »
Hi all,

My single spark lamda senor graph on gs911 hardly fluctuates . Bike blows out black smoke and uses lots of fuel. Plug is fowled . Had one error reported that lamda heating element  failure . Do I just replace sensor or check further.

Many thanks in advance.

And here is a Non-AI response.

Remove the Lambda sensor and test it to see whether it is actually working.
Remove it and place it on a flameproof surface.  Connect a multimeter (set to the smallest voltage scale it has) to the black and white wires.
Now heat the tip of the lambda sensor.  It's not an issue to get it red hot.  You should typically see the voltage climb to around 900mV when at its hottest. 
This will also clean the sensor of any carbon deposit or fouling.  If it gives you the correct voltage reading, put it back and test with the GS911 again.

Since your GS-911 reports a lambda heating element failure and you're experiencing black smoke and fouled plugs, it's likely that the lambda sensor is malfunctioning. Replacing the sensor should be your first step, but if the issue persists after that, you might want to inspect the wiring or check for any other engine management faults.
