What does the p1491 code on a Nissan mean?
If the EVAP canister is OK, and there are no other visual damage to the EVAP system (e.g. loose or broken hoses), replacing the vacuum cut valve bypass valve takes care of the problem. There is a factory service bulletin for all 1998-2002 Nissan models. What does this mean? The cost of diagnosing the P1491 NISSAN code is 1.0 hour of labor.
How much does it cost to diagnose Nissan code p0462?

Where is the vacuum cut valve on a Nissan p1490?
P1490 Nissan Description The vacuum cut valve and vacuum cut valve bypass valve are installed in parallel on the EVAPpurge line between the fuel tank and the EVAPcanister. The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank.
Why is my Nissan fuel level sensor low?
Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persists it may be necessary to replaced the fuel level sensor. What does this mean? The cost of diagnosing the P0462 NISSAN code is 1.0 hour of labor.

How to find the Nissan OBDII trouble code?
A particular trouble code can be identified by the number of four-digit numeral flashes. The ‘zero’ is indicated by the number of ten flashes. The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) – OFF (0.6-second) cycle.
How much does it cost to diagnose Jeep code p1491?
The cost of diagnosing the P1491 JEEP code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. When is the code detected?
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).

What does the vacuum cut valve on a Nissan Altima do?
The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank. The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed. It opens only for on board diagnosis. The vacuum cut valve bypass valve responds to signals from the ECM.
Where is the vacuum cut valve bypass valve?
The vacuum cut valve and vacuum cut valve bypass valve are installed in parallel on the EVAP purge line between the fuel tank and the EVAP canister. The vacuum cut valve prevents the intake manifold vacuum from being applied to the fuel tank. The vacuum cut valve bypass valve is a solenoid type valve and generally remains closed.
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 does the vacuum cut valve on a Nissan do?
The vacuum cut valve bypass valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the valve is opened. The vacuum cut valve is then bypassed to apply intake manifold vacuum to the fuel tank.

What is the code for the vacuum cut valve?
In this instance, code P1491 will set when the PCM pulses the EGR solenoid at a set duty cycle for a specific percent lift but does not see it reach that set location or lift via the position sensor. For the Nissan / Infiniti vehicles with the vacuum cut valve by-pass valve code P1491, see the “Related Codes” section for a detailed explanation.
