After a long drive on the highway, the Vehicle system malfunction error came on. The car behaves normally. No lipm mode. After I turned it off and start again the error disappeared.
Does anyone have an idea what the problem is? Mazda6 2.2 skyactiv 2016.

 

Any luck with this. Experiencing the same thing with my 2019 Mazda 3

 

I solved the problem. The error occurs due to an occasional drop in oil pressure. This is caused by a clogged filter on the oil pump. The oil clogs the filter because it is dirty due to bad nozzle washers. When replacing the oil pump filter, it is necessary to remove the valve cover and clean and place modified washers under the nozzles. If it is not clear to you, you can also find the problem on YouTube.

 

Thanks for the quick reply. To confirm, are you referencing the fuel injector nozzles? I am not overly familiar with those systems but I'm happy to learn via YouTube University. My mechanical skills are currently limited to brakes, spark plugs and oil changes.
