P1490: Understanding The Mysterious Fault Code And Its Implications
The P1490 fault code refers to the Vacuum Cut Valve Bypass Valve in the EVAP system of the vehicle. This valve is installed in parallel with the vacuum cut valve on the EVAP purge line between the fuel tank and the EVAP canister.
Its main function is to prevent the intake manifold vacuum from being applied to the fuel tank. The Vacuum Cut Valve Bypass Valve is a solenoid type valve that remains closed under normal conditions. However, it opens only for on-board diagnosis. When the Engine Control Module (ECM) sends an ON signal, the valve opens, bypassing the vacuum cut valve.
This allows the intake manifold vacuum to be applied to the fuel tank. The P1490 fault code indicates a problem with the Vacuum Cut Valve Bypass Valve.
It could be caused by a malfunctioning valve or an issue with the ECM signal. If this fault code is detected, it is important to have the valve and the associated components inspected and repaired if necessary to ensure proper functioning of the EVAP system.
