Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model).Clean out the EGR valve and/or tubing to remove deposits.There should be a noticable difference in RPM's with the EGR open Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage.Possible Solutions 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 may not be opening due to a lack of vaccuum.There is a blockage in the EGR (tube), most likely carbon buildup.The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced.There may also be other symptoms.Ī code P0401 most likely means one or more of the following has happened: pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. You may notice drivability problems such as pinging (a.k.a. Symptoms Possible sumptoms of OBD code P0401 The P0401 code means that OBD detected an insufficient amount of EGR. These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc.
There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. What does this mean? OBD Code P0401refers toĮGR stands for Exhaust Gas Recirculation. Generic OBD Error Code Details for P0401 Exhaust Gas Recirculation Flow Insufficient Detected This error means Exhaust Gas Recirculation Flow Insufficient Detected.īut for convenience I have reproduced that information here: Is appreciated for answering your question. Write to me of the findings and we will go from there. I would clear the codes first and run engine for two min and re-check codes. Here is the EGR solenoid valve part number and list price: Since the dealer already cleaned the EGR valve tube, I would suspect your problem is likely due to a bad EGR solenoid valve or a leaky vacuum hose to the EGR valve. If this solenoid is bad, or there is a vacuum leak in one of the hoses, the EGR valve won't open when it should setting the code. On your engine, the EGR valve is vacuum operated, and there is a little computer-controlled EGR solenodi valve in the vacuum hose that detemines how much vacuum the EGR valve gets. What usually sets the code is an inoperative EGR valve, or a carbon clogged port under the EGR valve. The code is set when the engien computer detects less than the requested amount of EGR flow when the engine is hot and is under load. The P0401 code is Insufficient Flow Exhaust Gas Recirculation System. Po115-Coolant sensor- indicates a open or short-circuit in the engine coolant temperature sensor circuit.
