You must test with scanner/computer for easy diagnostic, Otherwise you must waste time +money. Remember the electronic vehicle is very complicated . see the diagram attached, and see how many circuits or device.

SOURCE: navigation and radio code missing

Pull the radio out, take it to the dealer with your registration and ID. They will be able to get the reset code for you.

No-one is ever particularly happy to here this, but this is the way it is; we do have to keep in mind that the original idea of codes on radios was to prevent people who steal them from being able to use them.

So, if an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code (some people say that they have found the code on a sticker inside the glove compartment, but I wouldn’t count on that). Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The serial number will come up in two sets of numbers.)
Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number (or you can remove the unit and get the serial number from the back of the radio). Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.

Here is the URL for the Honda Owner page. If you register (no charge) you are able to get radio codes using the VIN number of your car, the serial number of your radio, and the
Phone Number and Zip Code that you give them when you register.

Hope this helps you with the process.

Would replacing the egr valve fix the other faults such as egr solenoid fault,egr pressure sensor fault and egr positionsensor fault


The EGR valve can be tested with a Vacuum pump. If the diaphragm is bad, the valve will not change positions. Hence the error Code for the position sensor not opening to allow the valve to work. And the error code for the pressure sensor not registering a change in pressure because the EGR valve did not work.

So both sensors can give a false Code. On the other hand, you will see both sensors have Vacuum lines and electric connections. When the electricity is switched on, vacuum is suppose to flow back to the EGR Valve. That is why the first thing you do is test the EGR Valve to see if the diaphragm is broke.

If the EGR valve holds pressure it should be okay. Then you would want to check for pressure in the lines coming off of the switches. Remember to clear the onboard computer each time you replace a part, or you will get 25-35 Startups worth of false information.

Both Autozone and Oreillys will scan or clear your car for free. I hope you find my solution very helpful. You usually don't have a complete failure of all 3 parts at the same time.

I have a 96 Honda Civic HX. When I am at idle the car starts to shake and the rpms fall almost to zero. I took the car to a mechanic and was told that I need a new Catalytic Converter and the EGR ports...


Yes and No. The EGR can cause the car to idle rough and or stall. I am assumeing the check engine light was on and set code for EGR and Catalytic Converter. If the engine isn't running right it is possible the cat won't work right due to improper air fuel ratio that the EGR is causing. To do repair proper the EGR should be fixed then clear codes and see if the code for Catalytic Converter. There are other reasons that would your car to idle rough or stall I am just assuming that this mechanic got codes or tested the EGR right.

P401 code?


P0401 OBD-II Trouble Code - Insufficient EGR Flow

What does that mean?
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.


Symptoms
You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.


Causes
A code P0401 most likely means one or more of the following has happened:
* The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
* There is a blockage in the EGR (tube), most likely carbon buildup
* The EGR valve is faulty
* The EGR valve may not be opening due to a lack of vaccuum


Possible Solutions
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
* Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
* Clean out the EGR valve and/or tubing to remove deposits
* Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
* Replace the DPFE sensor (with a good quality / OEM one)
* Replace the EGR valve


Hope this helped (remember comment and rated this).

2001 Honda Odyssey with a TCS and check Engin light on


you should have the codes pulled but its prob gonna be an EGR code. when the vehicle has an egr problem it will have decreased power that will cause the tcs light to come on due to the system being shut off by the check engine light code. prob just needs a new egr valve and the light cleared.

Battery discharegd every 4th days if the car is parking


Hi,
Possible causes for battery being discharged while installed in a vehicle could include among others:
  • a shorted diode (out of 6) in the alternator;
  • dome/courtesy light left on or switching on;
  • faulty/wet,corroded door switches;
  • false triggering of the alarm;
  • partially faulty car stereo system (memory retention).
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

2000 Honda Accord EGR Valve Error P0401


Jason,
-after you change the part you have to reset/clear the code

-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete all codes/radio presets/etc) but it will also clear the 'check engine' code
-this is what I do AFTER i write down my radio station presets :)

-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also

-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works
thanks
