Question about 1996 Honda Accord
The o2 sensor. o2 sensor heater, catalyst and egr monitors are not ready
Louie ramirez if the monitors are not resetting right away its because something was repaired recently to do with the emissions and a trouble code was erased or cleared to remove the check engine light .now there should be no more check engine light on but you have monitors blinking on your scanner right ,now to turn those monitors off all you have to do is drive the vehicle and monitor with a scanner some cars clear right away and some can take up to 500 miles before the monitors clear ,don't panic its this a typical normal procedure just drive it should clear soon and good luck.

Testimonial: "I've been driving it all different speeds and conditions. 1st about 300 miles. then got frustrated and unplugged everything to see if it would reset the ECU. It didn't. All the same monitors were still ready with the same 3 not ready. Since there were no codes to begin with to make the monitors not be ready I'm starting to think the ECU has a problem. It just doesn't make sense for them to not be ready when there was no codes in the first place. Do you have any other suggestions? I'm up to another 193 miles again and they are still not ready"
Low voltage can cause these codes check charging rate if ok reset ecm by removing both battery terminals and touch them together for 15 sec. if codes return catylist my be clogged. also as always check for blow fuse in under hood fuse box

Testimonial: "I do know low voltage can cause these problems, but I don't have a voltage issue or weak battery. I have never heard of touching the battery terminals together to reset the ecm. How does that work? there would be no voltage obviously in the cables. So how does that reset it?"

Further clarification on the O2 sensor location: It is in the exhaust pipe, under the center of the car, on top of the pipe, just aft of the oil filter.

SOURCE: O2 sensors
There are 2 O2 sensors on your Honda. Mine failed it's inspection due to the emmisions. One of them is on the exhaust manifold the other is just below. I purchased mine at Autozone. You could get them anywhere similar. It runs from 50-85 bucks each. Kinda expensive yes, but very simple to due.
You only need a couple of adjustable wrenches and some rust remover or bolt loosener, cause those things are gonna be a @#$%^ to get off without stripping them. If that happens your in trouble. Just remove the exhaust manifold cover and you should be able to get the old one of and just put in the new one twist it tight and your set. The one down below is a little more difficult. Depending on wether it is connected to the cat converter or not. Mine wasn't but i drive a civic. If its not connected than you can replace it the same way you did the top one. If it is connected to the cat then you need to get someone with specialty tools. And remove that piece of the exhaust then install.

If it was running fine prior to putting the new exhaust on, then there is either a restriction in the exhaust causing too much back pressure or something didn't get hooked back up.
