The dpfe sensor is the electronic part of the egr valve. This is very common problem with fords.
Some Fords have an extended warranty thru Ford on replacing the dpfe sensor I think the extended warranty is up to 60000 miles.
I would call Ford to run the vin number in there system to see if the extended warranty applies for your vehicle. Then take the vehicle in to service the DPFE sensor .

Good Luck

P0402 1997 Toyota Camry 4 cyclinder 4 door, encountered P0402 has 3 months already. The car is drivable. What is the solution? Could replacement of a vsv value resolve this issue? Which part can I buy


Hi,
That is the code for Exhaust Gas Recirculation Flow (EGR) Excessive Detected

Read more at: http://www.obd-codes.com/p0402
Copyright OBD-Codes.com

Go to the site and review what causes and can be checked to fix it.

I'd start w/cleaning the EGR valve - free fix - and then consider replacing the part. I'd look for USED parts @ a local Salvage/Wrecking yard vs. buying new, due the cost and the fact that this is an older car.

GL,

Code p0402??


Code 402 means the computer has detected flow in the EGR valve when it should be closed.
The valve would need to be checked out.

Hi there:

DTC P0402 - Exhaust Gas Recirculation Flow (EGR) Excessive Detected

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 P0402 code means that OBD detected an excessive amount of EGR.


Symptoms

You may notice drivability problems such as the engine may surge off idle. There may also be other symptoms.


Causes

A code P0402 most likely means one or more of the following has happened:

  • The DPFE (differential pressure) sensor is faulty and needs to be replaced
  • There is a blockage in the EGR (most likely carbon buildup)
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum

Possible Solutions

With a P0402, it is common for people to replace the EGR valve, only to have the problem return. The most likely solution is to replace the DPFE sensor.

  • Check the voltage at the DPFE sensor both at idle and when the EGR is open
  • Replace the DPFE sensor


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Grand carvan gives p402 code


This is not a cut and dry fault code. This means that more than one thing wrong can set the code in the computers memory. Here is the low down on the P0402 fault code. This is from the OBD2 fault code diagnostic book.

P0402 - Exhaust Gas Recirculation Flow Excessive Detected
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine hesitation
Possible causes - EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- EGR volume control valve stuck closed
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Faulty EGR Valve
- EGR passage clogged
- Exhaust gas leaks

I believe the corrected code should be 402.


DTC P0402 means that the OBD has detected a excessive amount of egr gases in the system. The EGR system has three major parts in it, The EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). P0402 was triggered by one of the following, The DPF is faulty and needs to be replaced. There is a blockage in theEGR valve from carbon build up and needs to be cleaned or replaced. The EGR valve is faulty Lack of vacuum to the EGR to opperate properly. Most will clean the EGR valve and if that does not fix the problem, check the connection to the DPF and or replace the DPF. Good luck and keep me posted. be glad to help.
