2019 commander 800r last ride threw a p0302 code, cylinder 2 missfire, machine seemed to be running fine and no signs of missfire, the next ride the check engine light came back on with p1136, is that a bad o2 sensor?
Thanks for the reply, I was kinda thinking the same thing. You think the missfire could be caused by a bad o2 sensor? I have heard the factory plugs can have too much anti seize on them and cause bad spark, so was going to change them just as a good measure. And do you know if a 2019 has one o2 per cylinder or 2?
I think that the 0302 code is saying cylinder misfire because it is seeing a rich exhaust (un-burned fuel). I guess the question is: is it really seeing that, or is the sensor wigging out? When I look up the 1136 code, some say it's a lean condition, some say rich, but mostly "bank 1", depending on manufacturer. I would suspect the sensors, since you say it runs fine. Plugs are much cheaper, however . If plugs don't do it, I'd source the O2 sensors elsewhere. I think they're a Bosch, and commonly available for about half BRP's price. The parts fiche for your machine shows 1 per cylinder.
Awesome thank you! I can’t seem to find anywhere online that has a decent list of codes or a decent parts list 🤷🏻♂️ I have seen that o2 sensors are much cheaper online for the price I will probably just put a new one in bank one while I have it apart to do the plugs. The machine only has 1400 miles on it and runs perfect, no signs of missfire or running rich so I’m hoping it’s just a faulty sensor
I think you're on the right track. That is also how I'd approach it. Someone on this forum a while back found the sensors at a parts store. Maybe they'll see this and chime in. Here's some links to OEM parts and OBD codes for future reference.
1. turn key to lights on position 2. use mode button and scroll to engine hour (EH) on gauge 3. press and HOLD the mode button while quickly toggling between high and low beam ( min 3 toggles in 2 seconds) 4. If there is any P-CODES they will be displayed OBDII Codes Part 1 P0001 Fuel Volume...
man you’re awesome! Thanks so much, I’m gonna read through that and go from there, think I will end up putting a new o2 in and some new plugs and hopefully that solves the issue. I greatly appreciate that input!
