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

SOURCE: Code P0420

P0420 Catalyst System Efficiency Below Threshold (Bank 1)

There is one 02 sensor in front of the catalytic converter (called upstream), and one behind it (downstream). When the engine is warmed up and running normally the upstream oxygen sensor reading fluctuates and the downstream one is fairly steady. In the case where both readings are fairly steady, a P0420 check engine light code is set.

Possible Causes:
Oxygen (O2) sensor not working correctly
Damaged or leaking exhuast (pipe, manifold, catalytic converter)
Damaged catalytic converter

SOURCE: I have a 1998 Honda Accord the service engine soon

p1259 is a problem with the VTEC system. this system is for improved performance at higher rpm's. oil can get sludged up and clog the system, or the VTEC solenoid can just go bad. you can always have someone with a scan tool clear the codes to turn off the light, but until the problem is fixed, it will just keep coming back on

I have a 1996 Honda Accord EX. It was just serviced 0n 09/11. The following day the engine over heated and then the Engine Light went on. Brought it back to Valvoline, Guilford CT and they provided these...


http://www.obd-codes.com/trouble_codes/ here features your problem codes. 401 is an EGR or exhaust gas recirculation problem. saying exhaust gas is not getting back to the intake. this is almost a non issue. its there purely to help reduce emissions by your vehicle and a by product is actually more heat being shunted back to the motor and less power as bad gas gets mixed with good oxygen. the other is an oxygen sensor malfunction. this is concerning as the computer may be telling the engine to "Lean out" the fuel. pushing less fuel into half or all of the engines cylinders and when it burns it burns much hotter than a "rich" mixture. head to this link and start checking your engine for loose, cracked or damaged little black hoses called vacuum lines. http://www.obd-codes.com/p0171 that is likely why your engine cooked. the mechanic may have spilt oil onto the sensor too.

P0401 & P0171 Mazda Protege '02


It sounds like you may have an EGR valve sticking open. That can also cause the p0171 code, which means fuel system lean, and the p0401 which is insufficient EGR flow, kinda sounds like the valve may just be stuck open and not moving at all. replace the EGR valve.

OBD Codes P0401; P0171; P0174. EGER valve sensor vacuum tube winds up upon starting; will not idle. What have others found to be the issue? EGR sensor has gotten very hot and plastic tube connectors have...


p0401 egr flow insufficient. p0171 system to lean ( bank 1 ). p0174 system to lean ( bank 2 ). common problems that trigger p0401--
  • Restriction in the EGR passages, usually caused by carbon buildup
  • The EGR Valve is defective
  • Lack of proper vacuum or electrical signal to the EGR valve
  • Malfunctioning EGR Vacuum supply solenoid
  • Lack of proper EGR system feedback to the computer from the:
    • Manifold Absolute Pressure Sensor (MAP)
    • Differential EGR Pressure Feedback Sensor (DPFE)
    • EGR Valve Position Sensor (EVP)
    • EGR Temperature Sensor - p0174--
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling also
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure p0171- and p0174 are about the same.

How do you reset the check engine light for my 1997 Honda Accord? My catalac convertor is bad and I don't have the money to replace, but I need to get it inspected. I was told I could reset the lights so...


Even if you reset it you will still fail the test because the emissions monitor testing will not be complete. Once the monitors are complete the check engine light will turn on because the cat is bad. Its a catch 22.

If its just a safety inspection you may be able to get away with resetting the light. You can try disconnecting the battery for about a minute. or you can remove the back-up radio(clock) fuse from the under hood fuse block for about 30 seconds.

If you live in the continental US and your catalytic converter is bad your vehicle is not eligible to be licensed for on road use per Federal Emissions Laws.

Oxygen sensor showed up on inspection code P1259 and code P0401 i would like to purchase them and know how to fix them and by the way it's a 1998 honda odyssey


Go to autozone.com and register for free. Then you will have a full free online repair manual and also purchase the sensors there as well .I recommend it to everyone!
It is best to have a warm exhaust when removing the sensors. And use an 02 sensor socket only.

1998 honda accord obd code P0171 and P0170.


Hi,welcome to fix ya.
p0171 is for a lean fuel condition .A variety of things can cause this code the most common one is a bad o2 sensor but a plugged injector,fuel filter or dirty egr system can cause this as well.
