P2419EVAP System Switching Valve Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2419 reports that the control circuit of the EVAP switching valve reads low - usually the control line is shorted to ground, or the driver stage measures too little voltage. Karma's Revero/GS-6 bulletin lists P2419 for the rear fuel tank isolation valve controlled by the ECM. Subaru's bulletin 09-103-23 for 2015 Legacy and Outback with an evaporative leak check module (ELCM) tells technicians to look for P2419 and P2420 whenever the ELCM pump fault P2404 is stored, because the switching valve sits in the same module. Ford, by contrast, reports every circuit fault of this valve as P2418. CARB requires output components to be checked for circuit faults. P2420 is the high-side fault, P2418 the open circuit. The leak test is suspended and the warning light comes on.
