What P2419 means
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.
P2419 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2419
- Check engine light
- EVAP readiness not set
- Often stored together with leak detection pump codes
Common causes of P2419
- Most likelyControl wire shorted to ground (chafed near tank or frame)
- PossibleShorted coil in the switching valve or leak check module
- Less likelyWater ingress into the leak check module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2419 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 19 | The exact fault in that area. |
What to do next
- Note P2419 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2419
What does P2419 mean?
P2419 means "EVAP System Switching Valve Control Circuit Low". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2419?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2419 fail an emissions test?
Yes, it can. P2419 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2419 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2419 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
