Is this an EGR valve problem?
Symptoms Of A Bad EGR Valve Subpar Engine Performance. As the EGR valve monitors the volume of exhaust gases entering the engine, it is obvious that any issue with it will affect the engine performance. The Engine Warning Light Comes On. Seems so obvious! The Engine Does Rough Idling. Smell Of Fuel. Failed Emission Test. …
What does EGR stuck open mean?
Exposure to water and heat from the engine compartment typically leads to EGR valve failure. If the EGR valve becomes stuck in the open position, it eventually will cause a vacuum leak . If stuck in the closed position, the nitrogen oxides will rise and the fuel mixture will ignite before reaching the “explosion” section in the cylinder.
What is the purpose of an EGR valve?
The function of the EGR valve is to recirculate small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides. EGR valves can malfunction by becoming stuck open or closed due to carbon buildup.

Why do I keep getting code p0402?
- Excessive Vacuum signal or Electrical signal to the EGR Valve
- The EGR Valve is defective and is opening too far or not properly closing
- Malfunctioning EGR Vacuum supply solenoid
