Where under dash to test emission

The most common problem is A BAD GROUND WIRE!!!!!!!!! get a real tech to check it out!

The emissions are either running rich or lean or the NOX is high. The emissions have to be ckd & the computer scanned for problems. You can drive it but get it ckd out as soon as u can.It can be as simple as a vacuum leak

95 Accord is pre-obd 2 and will probably need dedicated Honda diagnostic equipment. There was no requirement at that time to use a standard connector or to place the connector within reach of the driver's seat as with obd 2.

Honda service information should provide more details or for simplicity ask your local Honda dealer to check the emission?

The simplest method would be to check the emissions the old-fashioned way - like it is still done in lots of places, by testing the emissions at the tailpipe with a suitable gasalyser...

you should not have to worry about it with the age of your car. nothing is wrong take it somewhere else to be tested

Mine just failed emissions test garage said its burning oil what is the soulution

After tightening the gas cap, you will have to drive the car a few 'cycles' before the light goes off. If that doesn't work, have the trouble codes read to find out exactly what is wrong and causing the light to illuminate.

This is a problem with your Cat converter Replacing car will then pass the emissions test, Air and fuel mixture if it was wrong your car wouldn't respond correctly and you would know something is wrong before you did any emissions tests, Also garage would have tweaked it for free for you as only takes a couple of mins

P0440- EVAP Emission Control Sys Malfunction

Something unspecified is wrong with the evaporative emission system. Check vac lines. Could be a loose electrical connection. This code has a very vague description.


P0302- Cyl 2 misfire

Has the car had a tune up in the past few years? Check plugs and wires, test for spark. Maybe a compression test. This issue may cause the next code.


P0172- Fuel trim Bank 1 , too rich

I would clear up the misfire first, then this code might go away.


P1613- MIL Call-up circuit open/Short to B+

Check the wiring under & behind the dash and instrument cluster. There apparently is a wiring issue, or the dash itself is shorted

P0420 means Catalyst System Efficiency Below Threshold, Bank 1
It means that your catalytic converter, in the exhaust system is not working fine, as its emissions are polluting the air too much.

The catalytic converter is part of the exhaust system. The way to test this part is by doing an emission test. The two OBD codes that you are getting are already a test telling you that the converter must be replaced, unless an emission test done at a garage says the opposite.

This kind of problem will trigger the check engine light, and your car will also waste too much fuel.
You also risk to get in trouble if the car goes through an Air Pollution control, as the car won't pass an emission test in this condition.

To conclude, the Catalyst System must be replaced, the O2 Sensors are fine.

This is a repair that should be done at a garage, however you can find DIY instructions here:How to Replace a Catalytic Converter or you can get more detailed instructions, and step by step illustrated procedure purchasing a repair manual.

i have a renult scinic 2004 1400cc emissions warning light on running uneeven and loss of power can this be sorted out what is it
