DTC P1491 - "EGR Valve Lift Insufficient Detected" is most often caused by a broken vacuum line going to the EGR valve. So I would check all the vaccum lines to be sure they are tight and not broken. Funny thing about vacuum lines, they never break out in the open, always behind or under something. Best way to check them is to remove them one at a time so you don't get mixed up and check them over carefully. If the vacuum lines are good, you will need to check the electronics that operate the EGR system. It is an involved procedure, much too long to include here. Go to the library, in the Reference section, and get the Motors Import Service manual. That has the complete, step by step, procedure for checking the system. Or you can get a DIY subscription to Alldata which also has the complete, step by step, procedure.

Whenever I get my Honda serviced at the Honda dealer there's a code printed on the service sheet. Maybe check it there or call a Honda dealer for advice.

Youigjt try unhooking and rehopking up the battery to try to reset it.

2001 honda odyessy has the following trouble codes: P1491, P0401,P1739. It has also been turning over longer before starting and has cut off while in park and idling. What does this mean?


P1491= "exhaust gas recirculation valve insufficient lift."
P0401= "exhaust gas recirculation insufficient flow"
P1739= ""3rd clutch pressure switch" (automatic transmission code)

the exhaust gas recirculation (EGR) valve is vacuum operated. there may be a vacuum line that is broken or leaking or become detached from the EGR valve. any vacuum leak will cause the engine to run lean, leading to poor starting and idle cut-off due to lean fuel fuel mixture.

The EGR valve has a vacuum diaphragm inside it. this diaphragm could be leaking. the EGR valve will need to be replaced if this is the case.

The P1739 code shows that a problem with the 3rd clutch pressure switch or the wiring leading to the switch has been detected. It may be an intermittent fault. Reset the trouble codes and drive for a while and see if this code returns. If so, check the wiring and switch operation of the 3rd clutch switch.

I actually had the same problem today and found the code in the weirdest place. I keep all of my maintenance receipts from the dealership and found the code on an oil change receipt. Very clearly said, "Radio Code".
