Has anyone else had this issue on the 850 engine code PO273

[CanDoo]

Engine code showed up PO273
The generic answer is an injector issue.
Dealer inspected sled - all parts and components are within specs -- they are unsure why the engine code came up.

My dealer is not sure why the code came up.


Anyone have this code and if so -- why --and a fix

Thx

I know there was a post about a injector wire breaking or rubbing.

It rubs on the airbox. Mine damaged the wires bad enough it needed a new engine harness

I would get the boys to look at the injector wires very closely Todd. I saw something like this on another forum on Facebook. Its very hard to see where the air box wears through the wire unless you inspect the wires very closely. Easy to miss for sure.

The guys probably put a dvom on the wire and think their ok. Probably not the case you need to power up the wires and put a load on it to test like a head lamp. Also need to inspect for chaffing/short to ground short to voltage.

Not all but alot of small engine techs really lack in drivibility and electrical. Small engine isn't a red seal chorse and they don't go in depth in the electrical and drivibility parts. This is a big part of why guys struggle and dealers get a bad name.
