Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello, let me review your request. Please stand by.
Sorry about the wait, p1491 is a faulty in the Vacuum cut valve circuit. The valve is located near the evap canister.
And are you sure the other code is P0462 as that code is not specified for a 2001 frontier
IS your vehicle 4 cylinder or 6 cylinder?
Ok, now i see it. P0462 is for the fuel level sensor circuit. Does your fuel guage work at all?
Then probably the problem is in the level sensor circuit. Very common issur on this model
For p0462 most common fault fuel level sensor in the gastank
For p1491 most common fault vacuum cut bypass valve next to the evap canister.
Do you have any other questions?
But you do not have an EGR code, you have a EVAP system code.
Attached is the factory info for the code p1491. The part is going to be available only from nissan.
