Lexmoto Viper 125 help needed

[rustyyyy____]

Hi,

Ive got a lexmoto viper 2019 125 which is having idling problems. Specifically, when I come to a stop whilst in gear, the bike will cut out unless I keep on the throttle and keep RPMs at 2k+.

The bike is fuel injected.

Ive ran it through an OBD and these are the codes its returning:

P0132: O2 sensor circuit high voltage bank 1 sensor 1.

P0231: Fuel pump secondary circuit low

P2300: Ignition coil A primary control circuit low

P0506: Idle air control, system RPM lower than expected

P0562: System voltage low.

Could anyone shed some more light on what these codes mean and how I would go about fixing them and the problems im having with engine cutting out.

Thank you

O2 sensor high voltage means the lambda sensor in the exhaust isn't working.

It's possible that all these are related to low voltage.

What voltage do you get at the battery when it's running?

my keeway was in a sad state when i got it, sans battery...Once all fixed 6 months later by me, I had some codes (with new battery). Clearing codes with OBD just made them come back...similar codes to the above.
Apparently, the ECU needed some training.

I cleared all codes first..then
Start bike from cold...keep revs above 3k for 10 seconds (that doesnt mean 9k is ok!!! just "above" 3k.). Keep revs there, count to 10 then shut off using the KEY.

bingo, all codes gone as ECU has now learnt whatever it needed to learn. My codes were related to ignition coil, lambda and fuel injector. Ive done about 1000km since...no check engine light.

As others above me have said, fix your low battery first...by using a voltmeter to confirm its faulty then buying a new battery. Or just buy a new battery. £35 ish.

It must have fitted at some point, otherwise it wouldn't be there. Has it been routed incorrectly?

I doubt its a fuel return pipe otherwise you'd have fuel pissing every where
when the bike ran plus most small bikes don't use fuel returns as the pressure regulation is done internally at the pump making it a one way system.

I suspect it may just be an overflow pipe linked to the filler
OR
mebbe part of the Air Injection System
you need to trace it to see where it goes and what it's linked to

11.8 is low for standing battery voltage and effectively flat.
You need to do a few tests to establish whether you need a new
battery or your charging system is iffy

When running say in neutral the battery should climb to around 14V
fairly soon with lights off or at least well over 13v if you have
always on lights.
If it does and the standing voltage drops below 12.4 ish pretty quickly
then the battery is iffy or you have a parasitic drain pulling ti down.

Filling it with electricity will not fix your fuel problem. That pipe has to be on.

As I said it's probably routed incorrectly. Is it held in by a strap that can be released that can give you more reach?

Battery voltage is low. Could mean a new battery, could also mean the regulator's not doing its job. If you put a multimeter on the battery when the engine is on (assuming you get past this pipe issue) then let us know what voltage you get.

Thats probably where your unconnected pipe is supposed to be connected....

I really should stop helping people like you and let darwin take care of the problem.

Were you repeatedly starting it when it was pissing fuel everywhere?

13V with some revs is a bit low, >14V is ideal. Might not point to an actual fault though, could just be shitty Chinese electrics
