Have a 2017 Honda Accord 2.4L Engine.. Got no more than 3 kms from the House and the Engine Light came on, immediately turned back for home.. The Engine Light was not blinking, just stays on even after I pulled back in the laneway and shut the engine off for a few seconds.. The Owners Manual says one of two possibilities , either the Gas Cap or an Emissions Problem ?? The Gas Cap is Fine Any idea what the Emissions Problem could be ?? We have a 170,000 kms on the vehicle.. Cheers Thanks

 

Does your car have an aftermarket air intake? Had the same issue, did both 02 sensors nothing seemed to work until I went back to stock air intake
