How much does it cost to replace the EGR valve on a Jeep Liberty?
Jeep Liberty Exhaust Gas Recirculation/EGR Valve Replacement costs $540 on average. What is the Exhaust Gas Recirculation/EGR Valve all about? The EGR (Exhaust Gas Recirculation) valve helps lower the car’s exhaust emissions (gases from the tailpipe).
What should I do if my EGR valve is not working?
During the EGR valve replacement, your mechanic should also inspect the vacuum hoses connected to the EGR valve. If the vacuum hoses are cracked (leaking), the EGR valve will not function properly. Scan the computer system in the car.
Why does the fuel management light stay on when the EGR is open?
This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.
How much does exhaust gas recirculation cost on a Jeep Liberty?
Jeep Liberty Exhaust Gas Recirculation/EGR Valve Replacement costs $540 on average. What is the Exhaust Gas Recirculation/EGR Valve all about?
What happens when your EGR valve fails to open?
The “check engine” indicator will light up on the dashboard when your EGR valve fails. This will happen the moment your vehicle’s central computer senses that the valve is in an abnormal position. For instance, if the EGR valve fails to close or open as it should, the computer will detect an issue and activate the “check engine” light.
Why is my a / C not working on my Jeep Liberty?
Why Isn’t My A/C Working? What are common reasons my Jeep Liberty has air conditioning problems?

Blower (fan) motor, A/C compressor, condenser, evaporator, heater system, automatic climate control, refrigerant leakage, electrical failure.
Where is the EGR valve located on a car?
It usually has a diameter of three inches and is located at the side of the engine but towards the upper part. On these past models, there is a vacuum hose that runs the EGR valve. The tube connects the upper part of the EGR to the carburetor. The valve’s metal disk contains a vacuum diaphragm, a plunger, and spring.
What does the EGR valve do in a car?
The EGR valve is responsible for taking the gas that comes out of the engine, and sending it through the intake manifold, where the engine can utilize it again. Without the EGR valve your vehicle will not recycle and reuse any of its gas, which increases the emissions.
Why does my check engine light come on when my EGR valve is stuck?
Whether the EGR valve is clogged, stuck open, or stuck closed, you’re going to get a check engine light. While the check engine light will usually point you straight to the EGR valve, it is possible that it might come on due to a symptom instead of a cause.
What causes a failure code on an EGR system?
Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer. An example would be at engine idle or when the vehicle is cold.
Where is the EGR valve on a Liberty Diesel?
Remove the bolts from the top of the engine cover on the engine, using a socket and ratchet. Lift the cover off the engine and set it aside. Locate the EGR valve on the back of the engine near the driver’s side head. Remove the clamps from the cooling lines on the EGR valve then pull the two coolant lines off the valve.
What to do if your EGR valve is blocked?
When the EGR valve is blocked, error codes of P1404 and P1406 may display on the engine light area. Remove the plug and clean it using the valve cleaning kit to remove blockages.

What does EGR stand for in exhaust valve?
EGR Valve stands for exhaust gas recirculation valve, which breaks down exactly what it does. Recirculating the exhaust does a few things for overall performance. First, it optimizes the fuel to air ratio without pulling in extra air from the intake.
