What is a Nissan EGR valve?

The Exhaust Gas Recirculation Valve, or more commonly known as the EGR valve, controls the engines emission of nitrous oxidize or Nox. It helps your vehicles to efficiently burn unused fuel by recirculating a portion of your exhaust through the process again.

What is Nissan EGR?

The EGR (Exhaust Gas Recirculation) valve helps lower the car’s exhaust emissions (gases from the tailpipe). It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions.

What is P0400 code mean?

P0400 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve is not flowing recirculated exhaust gases when it is commanded to open the flow of gases into the intake manifold.

Is it worth replacing EGR valve?

On older cars operated by engine vacuum, the EGR valve diaphragm can deteriorate and leak, causing a rough idle and a check engine light. In that case, the valve should be replaced. Also, over time the valve can accumulate carbon buildup and stick open, causing a rough running engine.

What causes EGR valve failure?

The failures are usually caused by a build-up of deposits in the EGR valve over a period of time that causes them to stick. This build-up is part of the ordinary operation of the vehicle and should be regarded as a serviceable item requiring repair or replacement.

What happens if EGR valve is stuck open?

If the EGR valve is stuck in the open position, the vehicle will experience a rough idle or frequently stall. If the valve is not completely stuck open but never achieves a tight seal when it closes, the engine can “miss” or shudder because of the improper mixture of the combustion elements.

Where is EGR vacuum solenoid located?

It is normally attached to the engine block with a nut and is close to the EGR valve. The solenoid can be located by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid. Replacing the EGR solenoid can be done in just a few minutes and you can save time doing it yourself.

Can the EGR valve cause starting problems?

The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases, into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting.

Under what conditions is the EGR valve open?

The EGR valve is closed when the engine is starting up. During idle and at low speeds, only a small amount of power is required, and therefore only a small amount of oxygen, so the valve gradually opens – it can be up to 90% open at idle.

Can I drive with a closed EGR valve?

Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.
