Remove the EGR valve and clean the carbon from the port it is connected to, they are known to get clogged up, you may also have a bad egr valve.

SOURCE: 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

YOU HAVE A TORQUE CONVERTER PROBLEM. TORQUE CONVERTER CONTROL CIRCUIT MALFUNCTION CODES CAN COME FROM ELECTRICLE TO INTERNAL MALFUNCTION. IF YOU START EXPERIENCING A HARD SHIFT OR FREE SPIN TO HARD SHIFT DON'T BE SURPRISED. TRY CHANGING FLUID. THIS MAY HELP. HONDA WOULD HAVE REPLACED TRANS IF UNDER 105 k FOR FREE. IF YOU HAVE TO REPLACE TRANS. BUY ONE FROM HONDA, 3 YR WARRANTY AND AS CHEAP AS A REBUILT TRANS. HAVE A QUALIFIED PERSON INSTALL, YOU WILL SAVE ABOUT $500 DOING IT THIS WAY. GOOD LUCK

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.

SOURCE: I have a 20001 Odyssey with 70,000. The check

unfortunately it is. Contact your local dealership to see if it may still be covered under a warranty or not.

Customer Concern: The check engine light is on with the trouble code P0740 present. Tests/Procedures: 1. Test drive the vehicle and watch the tachometer. See if the automatic transmission locks up. If unable to see the RPM change, and the Engine Control Module (ECM) is turning on the lockup solenoids, then the problem has to be internal to the transmission. The transmission has an extended warranty from Honda for 7 years or 100,000 miles. Potential Causes: Automatic Transmission
Lock-Up Solenoid
Torque Converter
Tech Tips: TSB #02-062 Diagnostic Codes: P0740

Service engine soon light stays on could it be a sensor?


Could as simple as a faulty or loose gas cap. Have the car scanned at Auto Zone for the DTC codes that would indicate the issue that needs to be addressed. Auto Zone scan free of charge too, so you can save money and they will give you the recommendation to address the issues.

Post back the DTC codes and be glad to help. Thank you for using fixya and be safe.

How to reset the check engine on a 208 chevy


Just disconnect the battery (negative terminal) and turn the headlight switch on for about 15 minutes. This should reset the PCM. Otherwise go to Advance and have them hookup the code reader and reset the codes. Thanks

Why is the reason why my check engine light comes on in my 2002 cadillac dts


You ECM has detected an issue with the engine and or transmission performance. You can take it to Auto Zone and have them scan the car for the DTC codes and they can advise you on how to address the issue. Auto Zone scan free of charge and if there are any issues, Auto Zone can give you the step by step instructions to getting the job done with common tools. Good luck and keep me posted, be glad to answer any questions you may have with the DTC codes Auto Zone will give you.

Service Engine Light Appeared - 1998 Ford Taurus


Take it to your local Auto Zone store. They will hook it up to a scanner for FREE and read the codes saved in the computer. They should give you a printout with the codes and possible problems with your car. You can decide where to take it to get it serviced knowing what the problem is. It's usually a bad sensor. Auto Zone could quote you a price on the part so you have an idea of what your repair bill should be. Auto Zone only sells parts. They do not install them. Good Luck!
