Massimo Buck Check Engine Light

[Michelle Holmes]

I have a Buck 450, 278 miles, one day driving down the road it stalled.  Now when I go to start the check engine light stay on. All started after changing oil.

Are you saying that it will still  run,& drive, after the first time it stalled. But now has a check engine light showing? 

[Michelle Holmes]

Massimo sent me a new throttle assembly, injector and still has no power.  I’m getting very frustrated, wish I never bought.  Nobody in San Antonio Texas will touch it

If it all started after changing oil, was the oil for wet clutches?  After that, most likely culprit is oil level or a loose connection somewhere since it is pretty new.

[kenfain]

TapBoss makes a good point, it really does seem to be related to the oil change. Check the things he's suggested, if that doesn't help, then you'll need to find out what trouble code is causing the check engine light.

Check the connection from the oil sending unit to see if it has a good connection and also check the ground.  If it happened just after an oil change make sure that you have the correct amount of oil in the crankcase, also sometimes the low oil sending unit has to have some time to refill after a oil change.

My buck 450 is running good, however I now have the check engine light....code is 0850. Where can I find out what it is? Thanks, Dan

Welcome to the forum U.P. Dan, sorry, but I can't easily answer your question. 

I suggest that you start a new thread, you'll get more exposure, and that should make it easier to get a faster response from someone who can answer your question. 

Good luck!

I have a code showing 10/3/3/7 what does this mean

CKP sensor no signal.  The 10 is considered a 0.

[Massimo]

Do you happen to know the part number or where I can get it

[Massimo]

Also does that sensor keep the motor from running steady wants to die

Look around here.

Bleed oil from the oil filter sometimes an air pocket or the filter does not have oil in it and will cause the light to come on.  To bleed the oil filter loosen the filter crank over the engine until oil comes out then re tight the oil filter, start engine.

Welcome to the very large  world of dis-satisfied Massimo owners.. I bought mine in 2017 . it broke on the first day.. To date, Massimo has never paid one dime for the many many repairs it needed.. only one shop will touch them in my state.. CASH ONLY up front!   Good luck........... BTW.. is that a Lhasa Apso in your pic?  looks just like mine that passed at 14 yrs old .. Loved that dog
