SOURCE: Question regarding a honda odyssey 1999 check engine light codes.

Ramon
P0420 relates to the catalytic converter. The computer sees little or no improvement in the exhaust before and after going through the converter. Either your oxygen sensors need replacement (3 total) or you need a new catalytic converter.
What is the mileage on the vehicle? Does it run well? Oxygen sensors generally start to fail after 70,000 miles. Catalytic converters usually fail because the engine is runnig rich and the owner ignores that fault for months. This causes the catalytic converter to overheat and fail.

P1456 relates to the evaporative emission system. This system holds the gas fumes in the system so they are not vented to the atmosphere. The most common cause of this code being set is failing to properly tighten the gas cap after refueling. Take the cap off and clean the sealing O-ring. Put it back on and tighten till it clicks 3 times. Make sure you have the correct gray colored gas cap. Clear the code and see if it resets within a few days. If it does, try replacing the gas cap.

SOURCE: Check engine and d4 lights on

d4 is flashing as a trouble code for the automatic transmission... i would say without research that it is a code for a transmission solenoid. maybe while washing the car some water got in and caused a short...these solenoids are usually weatherproof....you could try disconnscting the battery for 30 secs..to clear the trouble code and then start the car. remember you may lose your preset info!

Maybe the solution
There is a recall on the ignition switch,
My 99 Ody with 120K would suddenly switch off and come back while runing, Take it to dealer and report to Honda, Since out of warranty. The dealer would do the repairs estimated at $100 charge to you.

SOURCE: rough idle when warm and in gear, idle pulses slightly every now and then, check engine light is on

It sounds like the timing belt is off a tooth. Did you have it scanned to see what code was in the computer? These engines will surge when the cam timing is off.

1995 Honda Odyssey automatic. randomly it will have a slight jerk, then check engine light comes on and d4 light blinks while driving on freeway. the speedometer works fine when these lights appear...


First thing to do is have the computer checked for trouble codes. The blinking D4 light means overdrive is not going to function, probably because of the rough running engine.

My honda odyssey engine light on and d4 light flashing


If you check engine light is on - take your car to Advance Auto - they will check this for you for free most places. Due to the use of a computer in your car you must have this done to generate a CODE - this CODE will tell your mechanic and you plus me what the problem most likely is.
Get the CODE and follow those instructions. Most likely then the other light will also go out.

My 1999 Honda Odyssey Van has ~ 205000 miles on


I'm surprised a dealership made that mistake. Honda did start making engines to take oil until around 2003. I would go back and have them put the correct oil in the van. 5W-20 is not as thick as 5w-30, so the engine may start to make louder noises down the road. Just stick with 5w-30 for what the engine was made for.

I don't know how to reset the maintenance light. Can you let me know how to do that. I've done all the maintenance to it and just need the light to shut off. Thanks a lot for your time and efforts, David...


I ran into the same issue. Here's how to fix it.

While the car is off, push in on the odometer reset button and turn on the car.
Continue pushing in the odometer button until the light goes off.
Release the button after the light goes off (usually about 3-5 seconds)

Honda is notorius for bad MAIN RELAYS the solder in them crack and can not be seen with the nacked eye. This is due to simple expansion & contraction the solder heats up & cools down. Try that.
