Usually it's the solenoid that supplies vacuum to the EGR that fails. Trace the EGR vacuum supply line back to the solenoid and test it to make sure it clicks, allowing vacuum to flow to the EGR valve. If it doesn't click when current is applied to it, replace it.

A bad EGR valve could cause your car to experience hard starting, a rough idle, cruise control surges, popping noises from the exhaust, backfiring and sudden engine stops with cold weather or after deceleration.

My car turns off when i start slowing down or when im pressing on the break, i tested it and it gave me 2 numbers a P1491 and a P1456 my car is a 99 honda accord ex, a 4 door.


P1491 = Exhaust Gas Recirculation (EGR) Valve insufficient lift.

P1456 = Evaporative emissions (EVAP) control system leakage (fuel tank system).

Check the EGR valve for a failed vacuum diaphragm. Check the fuel filler cap to make sure it is the correct factory style, has a good check valve and is on tight.

Check your main relay. It powers the fuel pump and the ignition system. They are a known problem, with a high failure rate, on the 90-93 accords. I do believe it's worth checking.

Check the EGR vacuum regulator and make sure you have battery voltage to the solenoid. If voltage is present then check the regulator resistance. To check resistance you need to remove the wiring harness and using an ohm meter make sure that it is within your vehicles specifications. You can also try testing the vehicles Differential Pressure Feedback Sensor.

Failed emission NOx on a 93 Honda accord ex its papes the 25/25 test but not the 50/50 test. what is wrong how do I fix this? check engine light stays on?


The only thing I can think of checking would be the EGR valve, a faulty cat converter or faulty o2 sensor. Converter shouldn't set off check engine light though unless it is clogged causing too much back pressure, most likely EGR Valve.

The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. When the EGR valve goes bad, it must be replaced.

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

Here is a picture of where the EGR Valve is located (Accord 1999). Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.

If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.

Another times, the clean is the solution...I hope help yoiu with this. Good luck, and remember rated this help.
