Possible Cylinder Head Gasket problem.
Check for any coolant leaks coming from the cylinder head gasket.
We have seen head gasket failure and a few with cracked heads causing air pockets at the thermostat as well.
Check if the lower radiator hose is cool when the engine is hot. If so, the thermostat is not opening. Possible air pocket behind the thermostat preventing it from getting hot and opening. Verify Heater core return has flow and there are no external coolant leaks, which could allow air to get into the cooling system.
Problem Reported: Check Engine Light for Running Rough and Difficulty Starting

<p>The exhaust recirculation valve (<a href="/exhaust-gas-recirculation-valve">EGR</a>) on the 1999-2016 Honda Odyssey V6 may fail, causing:</p>
<li>Illumination of the<a href="”/check-engine-light”">check engine light</a></li>
<li><a href="/trouble_codes_3">OBD trouble codes</a> <a href="/OBD-II-Code-P0401">P0401 </a>and P1491</li>
<li>Reduced fuel economy</li>
<li>Hesitation or stalling</li>
<li>Long cranking before engine starts</li>
<li>Failure of state or federal smog tests</li>
<p>The EGR valve has open and closed positions, and opens or closes on command from the computer.</p>
<p>Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.</p>
<p>To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.</p>

Problem Reported: Check Engine and D4 Lights Flashing
May 27, 2010, 11:08 AM
<p>The Honda Odyssey may develop issues with the automatic <a href="/transmission">transmission</a>.</p>
<p>Rough shifting may occur, and the “D4” light and check engine may begin to blink. The <a href="/symptoms/check-engine-light">check engine light</a> will also illuminate, and <a href="/trouble_codes_1">OBD trouble codes</a> <a href="/OBD-II-Code-P0700">P0700</a>, <a href="/OBD-II-Code-P0730">P0730</a>, <a href="/OBD-II-Code-P0740">P0740</a>, <a href="/OBD-II-Code-P0780">P0780</a>, P1768 and/or P1768 will be stored in the computer.</p>
<p>If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty<a href="/automatic-transmission-fluid"> transmission fluid</a> may be the case.</p>
<p>In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.</p>
<p>The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF <a href="/how-to-pick-a-maintenance-schedule">replacement intervals</a> and procedure.</p>
