2002 Acura MDX Q&A
2002 Acura MDX Question: What is the significance of the Malfunction Indicator Light?
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. - Mrsme
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? - ziptie12
po301 is a misfire code...have them check that... - your.mechanic
