After market exhaust and FI light.

[Chris]

So I have a Suzuki Van Van 125 which is fitted with Mivv Exhaust, the lambda sensor has been removed which results in FI light being on. Elinator plug fitted and also tried clearing error in dealer mode but no success. Apart from drilling and threading exhaust pipe to reinstate sensor is there any other way to resolve this problem? 

[Gerontious]

stick a bit of tape over the light.

Have you checked that the code is actually the O2 fault code?

 

Is the eliminator working? If I remember right they're basically just a resistor so check the reading off it.

 

Back in the day when I ran a VanVan most guys who knew them well reckoned the factory setup was as good as it gets, apart from the gearing being too high. Aftermarket exhausts usually caused problems, some resulting in higher oil usage as well.

Yes checked the error code '44' and have tried 2 eliminators but light stays on. Have also tried unplugging Ecm and disconnecting battery to clear any old codes but that didn't work. I would assume that the eliminator would clear the fault? The performance seems fine with no loss of performance and idles smooth.

ignore it then.... seems my earlier reply was seen as a joke. but it wasn't. this is the usual fix for this precise situation. though in days past people would go a step further and remove the bulb from the panel.

[Copycat73]

did you switch on the ignition before you put in the eliminator plug ?

[Chris]

No?

the only suggestion i have is the system is fitted with an OBD or OBD11 .. which will store the fault code until it is cleared .. your assumption that the O2 sensor has caused the light may not be correct .. either buy a reader and clear the code yourself .. or take to a dealer .. incidentally  i am told that a engine management light is an mot failure ..

This is true. Also applies to Tyre Pressure Monitoring and ABS lights.

Taking out the bulb is also a MOT fail. 

[Gerontious]

Maybe im missing something, but I see no mention off any of this in the current motorcycle MOT manual.

in fact.. as far as I can tell, the only lights on the dash that are checked is the indicators.. and you can get round that if the front indicators are visible.

 

are you sure you're not confusing the bike MOT with cars.

 

current manual.  https://www.gov.uk/guidance/mot-inspection-manual-for-motorcycles

 

if im wrong then call me a fool...  but please point out the relevant sections so I don't make an idiot of myself again in future.

[Copycat73]

it says nothing about ABS. lights in that manual either .. but that is a definite fail also.

You may be right. I know the guy who does my MOTs always checks them but then he's quite fussy and mentions anything he spots whether it's MOT critical or not. With cars it's definitely the case which probably means it will be for bikes before too long if it isn't already.

You may be correct.
When the new style MOT’s came in “warning lights” on motorbikes was mentioned specifically engine management and ABS, where fitted. However they are not in the latest bike checksheet.

Can confirm the bike passed its Mot with warning light. They said it has no effect on the safety of the bike. Anyway I'm in the process of refitting the standard exhaust as this came with the bike when purchased. The Mivv exhaust is a bit too loud for my liking. So I can refit the o2 sensor and resolve the problem. 

[Bender]

I know 2 testers will ask and see what they say.

 

I doubt the abs light on would pass as that's part of the braking system all of which has to be fully functional 

[Chris]

Problem resolved. I have refitted the original exhaust with Lambda sensor and after 5 mins of riding the FI light has no cleared its error.
