The P0445 code on your 2019 Nissan Rogue indicates a short circuit condition in the EVAP purge control valve circuit. A short creates unintended current paths that prevent normal valve operation.
Short Circuit Effects
Unlike an open circuit where no current flows, a short circuit allows current to flow where it shouldn't. This can manifest as a short to ground (reduced voltage) or short to power (elevated voltage). Either prevents proper purge valve control.
Rogue EVAP System
The 2019 Nissan Rogue uses a 2.5L four-cylinder engine. The EVAP purge valve controls vapor flow from the charcoal canister to the intake manifold. When shorted, the valve may stay open, stay closed, or behave erratically.
Short Circuit Causes
Damaged wire insulation allows conductors to contact metal or other wires. Internal valve solenoid shorts reduce coil resistance. Water intrusion into connectors creates conductive paths. Pinched or crushed wiring causes internal shorts. Heat damage from exhaust proximity melts insulation.
Diagnostic Approach
Use Nissan Consult to read specific fault information. Measure purge valve solenoid resistance—very low readings indicate internal shorts. Test for unintended continuity between circuit wires and ground. Inspect wiring for damage, especially near heat sources or areas prone to chafing. Check connector for moisture or corrosion.
