If you have a P0401 code from a CEL, the first thing is to check the EGR vacuum modulator. It is a little well usually next to the EGR. Pop the cap off and dust the little sponge inside. Sometimes this gets stuffed up with carbon particles and causes recirculation problems. You should clean the tubes hooked to it while you are there. Reset the code and see if the light comes back.

Replacing the EGR is not a tidy job. It is an expensive part to replace and you will disconnect the three hoses and dismantle it from engine by two nuts. Save it for the later if the previous trick fails to work.

2000 toyota camry code p0401 change egr valve light came back on. Check for possible soulution. I'm having trouble locating the EGR Pressure Sensor (DPFE) at stores. Is there another name for this part...


First did you reset the computer after replacing the EGR valve if you don't the computer doe'nt reconize the new sensor so it doe'nt reset the peremiters.Then check all passages and lines in the intake manifold there could be a clogg somewhere.Go to www.rockauto.com and you'll find EGR pressure sensor for under $30.00.

I have a 2004 lincon ls v6 and I got the code p0401 I replaced the egr valve completely and the code still came back on, what do I do? Please help.... clueless.


P0401 is a low egr flow code. It is rarely the EGR valve and more often than not the DPFE sensor that has failed. To find the DPFE sensor follow the metal tube from the EGR valve to the exhaust pipe. There will be two rubber hoses attached to that tube. The DPFE sensor will be on the other end of those hoses.

Make sure there are no holes in the rubber hoses. This can cause false codes as well.

What's wrong with the code P0401 for camry 96


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 (DPF). 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.

There is a vsv (vacuum switching valve) located under the intake manifold that goes bad very often causing this code. Its hard to get to. Follow the hoses from the black plastic round valve(egr modulator) you see next to the EGR valve to find the vsv.
