What does car code P1491 mean?
P1491 – Exhaust Gas Recirculation Valve Insufficient Lift.
What does code p1491 mean on an engine?
What Does Code P1491 Mean? The Exhaust Gas Recirculation (EGR) system is used by the Powertrain Control Module (PCM) to recirculate exhaust gases back into the intake manifold of the engine in order to take up space where air and fuel would be.
What does Mil code p1491 mean on Honda Odyssey?
In some 1999–2003 Honda Odysseys and 2003 Honda Pilots, the EGR system may become contaminated or clogged. If this happens, the vehicle may hesitate or surge during light acceleration, and the MIL (malfunction indicator lamp)may come on with DTC P0401 (EGR insufficient flow) or P1491 (EGR valve insufficient lift).
Where is the EGR valve located on a 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.
What to do if DTC p0401 p1491 is stored?
If DTC P0401 or P1491 is stored, or if the engine hesitate or surges, clean the EGR port, install an EGR pipe kit, and clear the code. If playback doesn’t begin shortly, try restarting your device.

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.
