Why do an EGR delete Honda?
Removing the EGR will (with the ECU workaround mod) produce an important increase in combustion temperature. SO if the goal was to maintain a colder intake manifold to avoid detonation (like me), the internal cylinder walls are a lot hotter w/o EGR thus increasing the risk of detonation.
How can I tell if my EGR valve has failed?
You need to confirm whether the EGR valve has failed or carbon deposits have began upsetting EGR system and engine operation. Look for a round, thick, metal disc about three inches in diameter. In most cases, you’ll find it around the top area and to one side of the engine. You may need to look between and under some components on your vehicle.
What’s the best way to clean an EGR valve?
Cleaning the Valve: After removing the valve, use an EGR valve cleaner, if possible. However, you can use carburetor cleaner or solvent as well. Apply the cleaner to the passages at the bottom of the valve, intake and exhaust passages. Use a dull scraper and wire brush to remove carbon deposits from the bottom of the valve, plunger and valve seat.
Why is my exhaust gas recirculation valve not working?
After miles of service, the exhaust gas recirculation (EGR) system — especially the EGR valve — will lead to engine performance problems due to carbon buildup, components mechanical problems, or vacuum hose leaks.
What does the EGR valve do on a Honda Odyssey?
The Exhaust Gas Recirculation valve, or EGR valve, system in your Honda Odyssey reduces oxides of nitrogen by recirculating them back into the combustion chambers in your engine.
What to do if your Honda Odyssey has a vacuum leak?
By pulling the hose off the valve and hooking up the pump to the valve, you are creating a vacuum leak. Apply vacuum to the EGR valve. The vacuum should remain steady and the Odyssey should run poorly. If the vacuum doesn’t stay steady and the engine doesn’t run smoothly, replace the valve.
Why are the valves on my Honda Odyssey not working?
If the valve is malfunctioning, it can cause the engine valves to knock against the piston heads. In a Honda engine, this can be fatal for the valves because Honda uses a compact engine design, called an interference engine design, which causes the valves and the piston heads to intersect if the timing of the valves and pistons is not correct.
