Is EGR valve open or closed at idle?

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.

What kind of EGR valve does GM use?

Before we jump in head long into this article, you need to know that there are two types of electronic EGR valves that GM uses in most of their late model vehicles. The EGR valve that’s covered by this article are for 3.1L, 3.4L, and 3.5L GM vehicles from 2000 to 2009 models years (although some late 1999 models use this type of EGR valve too).

Is the EGR valve on my Chevy Venture defective?

Our 2000 Chevy Venture, with a 3400 SFI engine (3.4L) had a defective EGR valve, throwing fault codes of P0401, P0403, P0404, P0405, P1404. Symptoms included a Service Engine Soon light, poor gas mileage, rough idle, lack of power on acceleration.

What happens if you leave the EGR valve open?

Whether mechanical or electronic, EGR valves open and close to control the gas flow. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging.

Where is the entry port for the EGR valve?

Clean out the entry port. The entry port is where the valve tubes connect to the engine (usually the intake manifold) while the EGR valve is off. Reinstall the EGR valve.

What sensor controls the EGR valve?

EGR Fraction Based Control Critical sensors are an exhaust manifold pressure sensor (P2), an intake manifold pressure sensor (P2) and a speed density estimate of total mass flow. Exhaust and intake manifold pressures are used to control the EGR valve and VGT vanes.
