The check engine light on my 90 honda accord comes on after driving for about 5 minutes. When you turn the ignition off and restart the vehicle, the check engine light is off. It will come on after about 5 minutes of driving. The computer on the passenger side floor board shows to blink 43. I have replaced the O2 sensor and 1 year ago replaced the on-board computer in the floor board. Any ideas what could be causing the check engine light to come on.

Re: Check Engine Light is On
You did what thousands of people do they get a code and jump straight to replace a part no testing just guessing. code 43 is a fuel system problem code sure enough you absolutely need proffessional diagnostic help with this one you cannot go on another hondas code 43 because you can have two hondas exact same symptoms and even the color of the interior and have two completely different problems I realize it costs money to diagnose the problem but which is cheaper to pay diagnostic and only change the one bad thing or replace part after part then take it to be diagnosed and have them change one part?
Cmon Please do the right thing for your wallet honda is not a car for anyone but a professional to diagnose and fix.

code 15 is ignition output signal, an electrical problem. The engine computer sees no spark signals coming from the igniter. This is a good job for a Honda mechanic who isn't afraid of electronics.
THIS IS HOW YOU RESET THE CHECK ENGINE LIGHT ON THE 99 HONDA ACCORD. 1. With the Car Off, Press and hold down the Odometer Trip Reset Button. 2. While still pressing the Trip Reset Button, Turn the Ignition Key half way on where all your oil, check engine lights etc.. turn on. Don't turn it as far as you would to normally start the car. Wait a few seconds and the Check engine light will turn off. 3. Turn the key back to the Off position and you're done. What a scam Honda has with the BS Check Engine Light.
If the car shuts down after the service engine lights on, possible problem is the igniter on your ignition coil. You have to replace the igniter. I had the same problem before with my esi 93 and honda car shop fixed it by replacing the said part. It is better to have the code scanned first. If it gives you 1 long flash followed by 5 short flashes, definitely it is the igniter.
What model and year honda do you have? If it's an accord, 90-93, take a look at your distributor by checking for spark, when the engine dies. If no spark, it's usually a bad distributor on those year accords.
Remove the pass side kick panel (Plastic Part) that would be near the right of the passenger's foot. Locate a small blue plug. You jump the terminals together inside the plug with a paper clip. THEN, turn your key ignition on to power up everything but don't engage the starter. Count the amount of times the check engine light flashes. It's like morse code. A solid longer blink indicates the amount of the first number... a quicker flash will indicate the second number. Here's an example: ___ _ _ _ _ That would be code 14. Let me know what code you get and write back... I don't have room to list every code for 90-91 Accord. I'll check back frequently.
