Geopolis 250: Injection system diagnostic warning light

[nikma]

Please, does anybody know what is happening when injection system diagnostic light lamp showing when is scooter standing on minimum throttle?
When get more throttle, or getting a ride, lamp turn off or visible weakly.
I changed voltage regulator and check battery.
Thanks for your help.

Did You check voltage supply by a multimeter, low and high RPM?
Lamp visible weakly is not regular.
Maybe throttle and air intake to clean. How many km did you ride at all?
Sorry for my uncorrect english.

Thanks for answer Mix. I checked voltage. That is normal, on high RPM 14.3 V. I changed voltage regulator so could not be a problem itself. Maybe lambda sensor is fault.? Geopolis 250 has 17200 km. Thanks. I will check air filter and what else you suggested? Sorry for english, i am not speak Italian. Any suggestion ?
Many thanks.

Yes, the voltage is regular.

Maybe lambda sensor is fault.?

I'm not a mechanic but I know the measured voltage on a Lambda sensor is regular when it's from 0.90-0.95 to 1.05-1.10, going up and down with medium value 1 volt exactly.
When up and down period is too long, Lambda sensor is not reactive enough and it's fault, even when voltage stands too long on lower or higher value.

Geopolis 250 has 17200 km. Thanks. I will check air filter and what else you suggested?

I wrote wrong, not air intake but throttle body, in italian is "corpo farfallato". Dust can be cleaned by a spray throttle body cleaner.

Sorry for english, i am not speak Italian.

No problem, I understand what You write.
I hope You understand what I'm writing too...
