My check engine light for my Honda Accord 99 v6 is on. I have changed everything Honda told me to change but the light is still on. Please help?

Answer 1

if there is a auto zone around you take your car there they will do a dyno test on it for free i had a problem with my car that the light would not go off and i had a lose hose that was causing the problem did you put fuel injector fluid in your car to make sure the fuel injector wasn't dirty?

obd 2 systems can be very complicated, and once the code is triggered, it will stay in the ecu til its erased, a friend of mine was running into the same problems it turned out to be her gas cap which wasnt tightened correctly, and threw the code and it stayed there til it was erased, try disconnecting your battery, and see if it clears. if Honda did the reapirs, take it back to them and make them fix it.

By the way, if you enjoy modding you car, like i do, the check engine light may come on after doing work on your car. For instance, today, i put a short RAM intake on my 1999 Honda Accord EX-L V6. After completing the install, i unplugged the sensors and turned on the car for a sec to let it know that it should recalculate the air intake. I then reconnected the sensors and turned the car on. I let it idle for a while so it could recalibrate. After doing all this, I realized the check engine light, or malfunction light was on. I understood that this was because i had been tinkering, and of course i didn't want to pay $80 for a diagnostic, which would turn off the light. What i could have done, is wait, and after 40 startups with no problem the light would have turned off. Alternatively, what i did was REMOVE THE NUMBER 13 FUSE FROM THE FUSE BOX ON THE PASSENGER DOOR FRAME FOR 10 SECONDS AND THEN REPLACE IT. THIS WILL MAKE YOUR MALFUNCTION/CHECK ENGINE LIGHT GO OFF BUT THIS IS NOT RECOMMENDED AND I DON'T TAKE ANY RESPONSIBILITY IF YOU RUIN YOUR CAR. THAT LIGHT USUALLY DOESN'T LIGHT UNLESS THERE IS A PROBLEM. IF THE LIGHT COMES BACK ON AFTER A WHILE YOU SHOULD TAKE YOUR CAR TO A QUALIFIED TECHNITIAN BECAUSE SOMETHING IS REALLY <EXPLETIVE>'ED UP!
