EGR Valves

As its name suggests, the exhaust gas recirculation valve – EGR valve for short – recirculates finely metered quantities of exhaust gas to the engine intake system. By simply altering the chemical makeup of the air entering the engine and thus lowering the temperatures in the combustion chamber, it reduces the production of NOx for a much cleaner, more efficient exhaust. With so much at stake, you’ll want to fit a quality brand with proven OE technology…just like ours.

Exhaust Gas Recirculation Valve OE technology

With over 20 years OE EGR system expertise, our valves are fitted as OE to millions of vehicles worldwide. We bring this same expertise to the aftermarket, with a comprehensive range including rotary and linear configurations, all based on our proven electronically actuated EGR valve technology.

Built for tough conditions

Because of the harsh environment of its location on the intake manifold, we only use the highest quality materials such as robust stainless steel valves, high temperature internal components and RTV silicon seals. The result – a quality EGR valve, highly resistant to extreme heat, contamination, corrosion and wear.

Precision engineered

Even the smallest of differences in the shape of the valve head can affect both valve leakage and flow metering, leading to increased fuel consumption, carbon build-up and decreased vehicle performance. That’s why every Delphi EGR valve is precision engineered to match the OE design.

Super quick response time

All our valves feature fast opening and closing response times for enhanced engine control and lower emissions from reduced exhaust gas lag. The high opening and closing force also helps to minimize the impact of corrosion, ensuring a longer lasting part.

Resource Highlights

In this article, you will find out about how to stick an EGR valve on Renault Clio.

Vehicle Applications

Make	Model	System
Renault	Clio, Modus, Megane, Kangoo 1.5 dCi (2001 to 2005)	Diesel Systems

Summary

Engine running rough or laboring following an extended period of short journeys. This is often caused by soot build-up on the EGR (Exhaust Gas Recirculation) which sticks the valve in the closed or more importantly open condition.

Fault code	Fault	Possible Causes
P0400	No exhaust gas recirculation. Expected performance not reached. Engine goes into limp home mode.	The EGR valve does not open
P0401	Too little exhaust gas is being recirculated	The EGR valve does not open wide enough. Width restricted by impurities (carbonization). EGR valve opening time too short Air mass sensor defective or soiled.
P0402	Excessive exhaust gas recirculation	The EGR valve deviates from the correct point when open. The valve does not close properly. The Air Mass sensor is defective.
P0403	EGR signals wrong or implausible	Wear or soiling of the potentiometer in the EGR valve assembly. The temperature sensor is defective.
P0404	Exhaust gas recirculation is out of correct position. EGR signals are wrong or implausible.	Wear or soiling of potentiometer, pressure sensor, temperature sensor or Air Mass sensor.

Resolution

One of the most frequent causes of problems with EGR valve operation is deposits in the valve or seat.

The valve can be stuck closed, or
deposits have caused the opening width to be reduced, or
the valve does not open completely.
