What can I use to clean an EGR valve?
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
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.
Can a bad EGR valve cause a vacuum leak?
An EGR valve can become faulty in two ways; it can be closed all the time or open at all times. It could also remain clogged by carbon and debris. 1. If the valve sticks open When an EGR valve is an open position, it creates a vacuum leak. The leak results in incomplete combustion, which usually causes hesitation and rough idling.
What does the exhaust gas recirculation valve do?
The Exhaust Gas Recirculation (EGR) valve is found in most gasoline and diesel engines, and its purpose is to help re-circulate the engine’s emissions by returning them to the combustion chamber rather than sending them to the exhaust emission system.

What does it mean when the EGR valve does not have vacuum?
The vacuum hose that connects to the EGR valve should not have vacuum. Let’s take a look at what your test results mean: CASE 1: Vacuum WAS NOT present. This is the correct and expected test result since manifold vacuum should NOT be present when the engine is idling.
How does the ECM know when EGR is flowing?
When EGR is flowing, the pressure will rise in the hose connected below the orifice and drop in the hose connected above it, thus the Engine Controller (ECM/PCM, etc.) can determine if EGR is flowing and how much.
How does the fuel injection computer regulate the EGR valve?
The fuel injection computer is the one that regulates the opening and closing of the EGR valve thru’ the application and release of vacuum (through a vacuum solenoid). One side of the EGR vacuum solenoid (the one that has only one vacuum inlet port) connects to the vacuum port labeled with the letter J on the throttle body.
