Hello,   Noticed hesitation while driving that started somewhat intermittent but now continues to get worse.     Starts right up no problem.   Now the check engine light is on.   

How do I read the check engine codes on the 4.5 inch display?  only has the two buttons on the left side.   Saw one video where holding down the lower button while displaying settings show the codes.   That does not work.    I did recently change the oil but was a month ago,  and only have about 160 hours.  

Any info would be greatly appreciated.

Hesitation can be a lot of things, but most common is either fuel related or spark related.

Make sure the spark plugs are clean and gapped properly.

Check your gas, should be clean and 87 octane is best for these machines. Next would be making sure the fuel filter/sock is not clogged. After that, check fuel pump pressure.

Also check battery voltage at idle and as you step on the gas, I've heard of low/failing batteries causing issues and throwing a PPS fault or something like that.

Not sure about any tricks for codes, aside from taking it to a Can Am tech or dealer.

Was able to pull the codes and have P1171, P0130, P0131.   All look fuel related.   

Have new clean 100% gasoline,  no change.   Plugs look fine.   Battery is good.  

Time for the fuel pump and filter o be changed.

After reading some other posts decided to pull the fuel pump to check the o-ring.    The fuel pump o-ring was very lose,  so went to autozone and purchased an assortment and made one work...   Not ideal but guess what...   Fixed!!!     Runs perfect again.
