I had a similar problem with code PO401
The solution was to loosen up the throttle cable a bit.
Since the TPS value has to be at 0.0% at idle.

1997 volvo 960, check engine light on with P0401. These motronic 4.4 do not have EGR, p0401 mean insufficient EGR flow. How do you fix this if there is no EGR?


A code P0401 most likely means one or more of the following has happened:
* The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
* There is a blockage in the EGR (tube), most likely carbon buildup
* The EGR valve is faulty
* The EGR valve may not be opening due to a lack of vaccuum

In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
* Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
* Clean out the EGR valve and/or tubing to remove deposits
* Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
* Replace the DPFE sensor (with a good quality / OEM one)
* Replace the EGR valve

Check it and send us your advance.

I got a code P040 on my 2003 corolla toyota corolla. My check engine light is on. so what does all this mean?


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.

WHAT DOES CODE P0401 MEAN? CAN I REPLACE THIS? I HAD A DIAGNOSTICS TEST AND GOT THIS CODE.


p0401 means you have insufficient egr flow, what you will have to do is have the egr ports cleaned out. this will involve removal of the egr valve so it would be best to take it to your local dealer where they will be able to fix ya right up.
