What happens if EGR valve fails?

A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.

How much does an EGR valve cost?

The average cost for EGR valve replacement is between $332 and $413. Labor costs are estimated between $81 and $103 while parts are priced between $251 and $311. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

What does EGR valve do on a Jeep Wrangler?

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.

Do Jeep Wranglers have EGR?

Your Jeep Wrangler is ideal for tackling those rough, off-road conditions, but your ride won’t go very far with a faulty EGR valve. Wrangler EGR valves are now required on most combustion engines to control emissions, but if yours isn’t functioning properly, find a durable replacement by shopping with AutoZone today.

Is an EGR valve expensive to replace?

How much does it cost to replace an EGR valve? Based on Fixter’s repairs and replacement figures, EGR valve replacement cost (UK) ranges between £337 and £804. The average cost of an EGR valve replacement balances out at £465.

Can a EGR valve be cleaned?

To clean the valve, wear an acid-resistant pair of gloves. Put on safety glasses, too, as the carbon deposits could become airborne in the process. Spray the EGR valve cleaner onto the carbon deposits. Remove the carbon buildup with the use of a pipe cleaning brush and dull scraper.

How do I know if my EGR valve is working?

A vacuum-controlled EGR valve is easy to test with a hand-held vacuum pump (see the image). If the EGR valve opens and the vacuum holds for more than a minute, the EGR valve works. If a vacuum diaphragm inside the EGR valve is leaking, the vacuum will drop. Once the vacuum is released, the valve should close fully.

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.

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.

How important is the EGR valve?

Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine intake system for increased engine efficiency, reduced fuel consumption and lower NOx emissions.

Where is the EGR valve located?

The EGR valve is usually located near or attached to the intake manifold, with a tube running to the exhaust manifold. There should also be a vacuum or electrical connector (or both) running to the valve which will need to be detached.

What is an EGR valve sensor?

The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.

What happens if I don’t replace my EGR valve?

#2 – Reduced Engine Power

If your EGR valve is malfunctioning or just clogged, the air-to-fuel ratio of your vehicle will be disrupted. This will cause all kinds of engine problems like a reduction in acceleration, fuel efficiency, and power.

Will a bad EGR valve cause stalling?

When the EGR valve is clogged or dirty, as they are prone to, it may not function properly causing the engine idle rough, stall at idle speeds, cause the car to get poor fuel mileage, or emit a strong smell of fuel due to excess hydrocarbons which also results in failing emissions tests.

How often should a EGR valve be replaced?

When to Replace the EGR Valve

Some will recommend getting it replaced every 40,000–50,000 miles. However, like with most other things in your vehicle, there is no mile number set in stone for when a piece of equipment will wear down and break.

How do you tell if your EGR valve needs to be cleaned or replaced?

How to Tell If Your EGR Valve Is Bad. Once you have removed your EGR valve, shake it lightly. If you hear something moving back and forth inside, that’s the diaphragm—which means there is a good chance that your EGR valve is still good and just needs to be cleaned to return to normal function.

How do you unclog a EGR valve?
