Hi I have a 01 Odessey that I love vey much. I just had someone at auto parts store check codes from check engine light.
I got the following codes
p 1491
p 0301
p 0304
p 0305
p 0300
p 1399

What amI looking at here?
Before I go to a dealership and overpay is there one thing I should be looking at for a fix?

How could all my cylinders be misfiring like this? Is there a central control that could be the issue here?

 

P S It is a 6 cylinder

Thank you for taking the time....sounds like I am up *&$%creek without a paddle! I only hope it is a central unit causing the misfires and not individual units!

 

not yet, how many miles do you have on the odyssey, it may be a minor tune up. It could be an individual coil, it could be the plug wire. The hondas don't go bad all at once, and they last a long time. Do you have a service manual or helms or chilton to help you out on trouble shooting and repairing your van?

 

egr valve might be dirty with carbon, or vaccum line is not opening the valve all the way, check line, or remove egr and clean off carbon, and or ck the diaphram for proper travel. Or may want to send to the the shop to fix. May call around and find out if there are any good shops that work on your type van.
