What does it mean when Honda Odyssey says p1491?
P1491 HONDA Tech Notes In some 1999–2003 Honda Odysseys and 2003 Honda Pilots, the EGR system may become contaminated or clogged.

Why is my EGR valve not setting p1491?
The most likely problem is the EGR valve / solenoid. If the P1491 code stays active and the P1498 does not set, we will need to test the sensor’s / solenoid’s associated circuits. At this point it may be wise to seek assistance from a trained automotive diagnostician.
How does the Honda p1491 exhaust gas recirculation system work?
P1491 Honda Description. The Exhaust Gas Recirculation (EGR) system reduces Oxides of Nitrogen (NOx). NOx is generated by high combustion temperatures. The EGR system lowers peak combustion temperature by recirculating inactive exhaust gas into the air/fuel mixture, thus reducing NOx emissions.
What to do if your fault code is p1491?
If the P1491 is the only active fault code present, and there are no updates/TSBs for your particular vehicle, then the next step is to locate the EGR Valve / Lift sensor / position sensor. You can usually find the EGR valve mounted between the intake and exhaust manifold of the engine. Once located, visually inspect the connectors and wiring.
