Short Term Fuel Trim (STFT) -- The correction factor being used in closed loop by the PCM to maintain a balanced fuel mixture. http://www.samarins.com/diagnose/p0401.html

Egr Error Code P0404

Intake Air Temperature -- The temperature of the air in the intake manifold as read by the intake manifold air temperature sensor. When the EGR valve opens, the temperature on the intake side rises from the hot exhaust gases. Frankly I don't believe the 99.2% with AutoEnginuity on my truck since my Xray 6000 doesn't display same and both tools are displaying normal intake mass air flow. In this case the computer does not detect enough EGR flow.

Not sure a light would come on with these trucks; I know I can unplug the EGR valve, set 3 codes (p0403, p0405, p0406) and the light will not come on. You might find a hose with a hole in it or you could find a connector that is not seated all the way or some wiring that has been rubbed through.This The list goes on and on. What Is Egr Error Percentage Aftermarket scan tools tend to display a lot of incorrect data and parameters.

Many times this code will go away if you replace the EGR valve (but not always). Toevoegen aan Wil je hier later nog een keer naar kijken? It can end up in your eye when you least expect it!Once you given the system a serious cleaning, reassemble it and start driving. Source Other cars may have an electric solenoid- or electric step motor-operated EGR valve (see the example).

Symptoms You may notice drivability problems such as pinging (a.k.a. http://csimonitoring.com/error-code/ecu-error-codes.php Bezig... When this occurs, you may notice misfires and even have misfire codes along with the P0401. Some V6 Acura models also had similar issues. Egr Fault Codes

A: Test the DPFE sensor (read above) and check EGR passages in the intake plenum and in the throttle body; they are very common to clog with carbon deposits. BTW, do you have the latest update for your 4000 from AutoXray? You can access it from your iPad or smartphone. this contact form Hope this helps.

I only ask since you mentioned the aftermarket intake filter. P0401 Code Toyota Camry Toyota Camry/Corolla: In Toyota Camry with the 2.2L engine, the code P0401 was often caused by a bad VSV (Vacuum Switching Valve) for the EGR, located under the intake at the Clogs can occur at many points in the system.

The scan tools I'm used to list EGR duty cycle (what the PCM is commanding) and EGR valve position (the EGR valves response to the command). These are PIDS that are captured when a fault occurs so you can refer to them later when diagnosing the problem.

If commanding the EGR valve open has no effect on the engine idle, the EGR system is plugged up or the EGR valve is inoperative or stuck closed. If the LTFT is higher than 10 either way, it may indicate a problem. Mazda Protege: In Mazda Protege, rough idle with codes P0401 and P0300 could be caused by a stuck open EGR valve. http://csimonitoring.com/error-code/emc-error-codes.php I'll explain.The P0401 error code specifically means you have "reduced flow" in your Exhaust Gas Recirculation system.

My dad replaced the EGR valve and disconnected the battery to reset code, but the Check Engine light came back next day while driving on a freeway. Strange thing is, it seems to run just fine.

They also explained why they don't pick up some of the EGR codes - such as when I unplug it. I found port between intake and EGR clogged. Also the OBDII cycles would not complete with the EBP problem or when I had the EGR unplugged. The EGR system consist of three parts: EGR valve, DPFE (differential pressure sensor EGR) and actuator solenoid.Car manufacturers created this system so already burned exhaust gas can flow back into the

When I had the EBP problem and was getting +99% error on the AutoXray 6000, my MAF was dropping to below 1 lb/min at idle because of the excess EGR flow. The ECM in an OBD II compliant vehicle constantly monitors and periodically tests the EGR system along with other emission control systems. The nitrogen oxides are formed as a result of the combustion in the engine cylinders. A computer system in all modern cars has a self-diagnostic and reporting capability or what is known as the on-board diagnostic or OBD II.

Honda/Acura: The code P0401 is common in Honda V6 engines. these both type of sensors do go bad.  However, the DPFE sensor is a much more common failure component that the EGR valve position sensor. I have a 2010 VW Jetta TDI, and check engine light went on. The EGR sensor, whether it's a DPFE sensor, EGR temperature sensor or EGR boost sensor need to be checked too.
