What does p0401 stand for in Honda Accord?
P0401 is a common OBDII trouble code that’ll pop up in the Honda Accord. It has to do with the emissions system and stands for: P0401: EGR → Insufficient Flow The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output.
What is the EGR system on a Honda Accord?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the Accord’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
What to do if your EGR valve is insufficient?
Most folks see P0401 Insufficient EGR flow, look up the price of an EGR valve, see how cheap it is and just throw a new one on. That can be a mistake. That’s because the EGR valve is not always going to be the culprit.

What are the symptoms of the p0401 OBD-II trouble code?
The EGR temperature sensor is not registering enough of a temperature change when the EGR valve is opened. The EGR passages are partly blocked and will not allow enough flow of exhaust gases into the intake manifold. What are the symptoms of the P0401 code? The Check Engine Light will be illuminated and the code is set in ECM memory.
Can a p0401 code still be stored in a computer?
If you have a P0401 code stored in the computer and have an electronic EGR valve but do not have a scanner to test it, you can still remove it and check for carbon stuck in the pintial of the EGR valve and even if the pintail moves up and down like it should. So my EGR valve checks out good but I still have this P0401 code?
What does DTC p0401 or p1491 mean?
