Is there a problem with the EGR valve p0402?
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 Related EGR codes: P0400, P0401, P0403, P0404, P0405, P0406, P0407, P0408, P0409
What does it mean when your OBD code says p0402?
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.
What causes a p040x code on an intake manifold?
A malfunctioning EGR system will cause several codes such as P0400 or P0401-P0409 to be displayed. Often a P040x code is caused by a blockage in the EGR system and is not caused by a failed component. Most common problem – carbon blockage where the EGR valve connects to the intake manifold
When to test the Ford EGR valve solenoid?
The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient. P01406 EGR Valve Pintle Position.
What does the EGR code p0402 mean?
What Does Code P0402 Mean? A malfunctioning EGR system will cause several codes such as P0400 or P0401-P0409 to be displayed. Often a P040x code is caused by a blockage in the EGR system and is not caused by a failed component.
What was the cause of the p0402 gas leak?
P0402 – Exhaust gas recirculation (EGR) system -excessive flow detected Trouble Code Fault Location Probable Cause P0402 Exhaust gas recirculation (EGR) system – Hose leak/blockage, basic setting not ca
What are the symptoms of the p0402 OBD-II trouble code?
What are the symptoms of the P0402 code? 1 The Check Engine Light will be illuminated and the code is set in ECM memory. 2 The engine could be running rough if the valve is stuck open. 3 The engine EGR system may have exhaust leaks at the back pressure transducer.

What does p0402 mean on a check engine light?
P0402 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Flow Excessive Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What causes the EGR temperature sensor to get stuck?
The EGR temperature sensor is registering too much of a temperature change when the EGR valve is opened from a partly blocked exhaust catalyst causing excessive back pressure in the EGR system. The EGR is stuck open due to binding or carbon deposits holding the valve open. What are the symptoms of the P0402 code?
What is the diagnostic code for exhaust gas recirculation?
P0402 OBD-II Trouble Code: Exhaust Gas Recirculation Flow Excessive Detected. Cost of diagnosing the P0402 code. P0402 is a diagnostic trouble code (DTC) for “Exhaust Gas Recirculation Flow Excessive Detected”.
