My daughter has a 2006 Honda Odessey. It all of sudden started rough and idling at 3000 rpm. We took it in and they work on it for weeks trying to find the problem. First they changed the oil pump as it was showing an 80 psi. The 2nd go round they changed the ECM thinking that may be the problem. Nope, still run rough and idled high. Then they found a problem. The spill valve was staying open. They changed the spill valve filter and she now runs better than before. The cost of all this was just over 900. Thank You Honda! Job well done.

Just thought this might help some who are having problems with rpm problems. My daughters 2006 honda Odessey was running rough and idiling at 3000 rpm. The Tech found the Spill or Spool Valve filter was clogged. Once they changed the filter, it is running better than before.
VTEC, the original Honda variable valve control system, originated from REV (Revolution-modulated valve control) introduced on the CBR400 in 1983 known as HYPER VTEC. In the regular four-stroke automobile engine, the intake and exhaust valves are actuated by lobes on a camshaft. The shape of the lobes determines the timing, lift and duration of each valve. Timing refers to an angle measurement of when a valve is opened or closed with respect to the piston position (BTDC or ATDC). Lift refers to how much the valve is opened. Duration refers to how long the valve is kept open. Due to the behavior of the working fluid (air and fuel mixture) before and after combustion, which have physical limitations on their flow, as well as their interaction with the ignition spark, the optimal valve timing, lift and duration settings under low RPM engine operations are very different from those under high RPM. Optimal low RPM valve timing, lift and duration settings would result in insufficient filling of the cylinder with fuel and air at high RPM, thus greatly limiting engine power output. Conversely, optimal high RPM valve timing, lift and duration settings would result in very rough low RPM operation and difficult idling. The ideal engine would have fully variable valve timing, lift and duration, in which the valves would always open at exactly the right point, lift high enough and stay open just the right amount of time for the engine speed in use.
VTEC was initially designed to increase the power output of an engine to 100 PS/liter or more while maintaining practicality for use in mass production vehicles. Some later variations of the system were designed solely to provide improvements in fuel efficiency, or increased power output as well as improved fuel efficiency. In practice, a fully variable valve timing engine is difficult to design and implement.
The opposite approach to variable timing is to produce a camshaft which is better suited to high RPM operation. This approach means that the vehicle will run very poorly at low RPM (where most automobiles spend much of their time) and much better at high RPM. VTEC is the result of an effort to marry high RPM performance with low RPM stability.

Good Read. My daughters 2006 honda Odessey was running rough and idiling at 3000 rpm. The Tech found the Spill or Spool Valve filter was clogged. They had changed out the Oil Pump and the ECM only to find it was a filter problem with the Spill or Spool Valve.Once they changed the filter, it is running better than before.

you dont need the throttle body ass.... all you need is the idle control valve and make sure that you radiator is full since this valve is control by the temperature of the coolant

I have an 03 Acura cl type s M/T, with Identical problems as you do. The worst events I had is
6000 rpms. changed EGR, Idle sensor, O2's. no effect.
did you resolve yours?

I have a 2011 Odyssey with 16K miles with a similar incident. I was traveling for the first time in the Blue Ridge Mountain area. The engine light came on, would not accelerate... The dealership says it's a failed spool valve. I picked it up today. Honestly, I don't want to keep the van now. When you spend 30K+ for a vehicle, the last thing you want is to be stranded and having it towed...especially when it's less than a year old.
I hope you have better luck.
#143 of 148 knocking noise on 2004 Odyssey
by edfamilyhonda
Sep 24, 2011 (3:34 pm)
About three years ago when the engine would get warm it would start knocking or tapping when it got warm. Now it does it all the time. When you rev the engine it gets louder until about 2000 rpms when it blend in with the engine noise. When you are waiting at a stop light you can hear it. It is on the passenger side and I do not know it is is the power steering or the valves need aqdjusting. Any help to figure it our would be helpful.
#144 of 148 Odyssey spit out spark plug

While driving along smoothly, why did my 2007 Honda Odyssey spit out the middle front spark plug and coil? It has 70000 miles on it and no one has ever removed or replaced the plugs.
Mechanic checked other plugs - all were in tight. Put coil in head (in place) and replaced plug.
#145 of 148 06 odyssey engine valve noise
by oillynails
Sep 13, 2012 (10:44 pm)
Hi, I've got an 06 Odyssey with excessive valve racket on one or two valves, but the noise stops
2500-2600 rpm on the way up and starts
the same rpm on the way down. Does the spool valve activate the VTEC
a set rpm or does it vary according to engine load. Once VTEC engages is it possible that it would eliminate the noise?
