2002 Acura MDX Question: What is the significance of the Malfunction Indicator Light?

 

Question

This light comes on periodically and then goes off after a few days (usually when I take off the gas cap, it goes off around the 3rd or 4th time). The service people tell me if it starts flashing that I have to stop driving the car immediately. So far it has never started flashing. This has been going on for over a year. The car seems to be running fine. I spent hundreds of dollars in service fees to fix it but it still comes on.

    Next time you have it in for service , get the specific trouble codes (DTCs) and reply with them on this post. We'll be able to help better with them. I suspect maybe one of the following; P0456 , P0457, P1456 or P01457. Lots of other possibilities though. Is it Acura/Honda dealer or independant shop?

    They have NO excuse for not getting it right! If you've paid for diagnosis and repair for that issue I would hold them to it if they say it's going to be fixed , then if the code returns it should be warranty, unless they have a valid reason for the failure(s).Next time your in get the code(s) and post them on this thread , Honda codes are the same ,as are their diagnostic and repair procedures.

    The DTC code is PO301. The light went on again today, and I took it immediately to the dealer while it was still on. They hooked it up and that code came up. Please advise. Thanks.

    Yes, that's what they told me. It's good to know that you are confirming what they told me. They showed me the monitor that indicated #1 misfire, PO301. It's interesting that it is misfiring because they put all new spark plugs in the car in 2010 when it had a little problem starting (that occurred before the malfunction indicator light ever started coming on). Car is still in the shop, so I'm wondering what is taking so long. When I left it, they indicated it should be a pretty simple fix.
    Thanks for your help.
