P2419 on Toyota
Evaporative Emission System Switching Valve Control Circuit Low
P2419 on Toyota vehicles indicates evaporative emission system switching valve control circuit low. Au7o has documented this code across 2 Toyota models — most commonly on RAV4, Sienna. Generic code set when the PCM detects lower-than-expected voltage on the EVAP switching valve control circuit (short to ground or broken wire), preventing proper valve operation. Typical repair costs on Toyota range from $150 to $500, depending on the specific model and root cause.
Common Causes of P2419
- •Short to ground or broken wire in control circuit
- •Failed EVAP switching valve
- •Connector/harness damage
- •PCM output driver fault
P2419 on Toyota by Model
Toyota RAV4(1 issue)
- 2006-2010 RAV4 Liquid Fuel in EVAP System - T-SB-0046-102006-2010
Toyota T-SB-0046-10 applies to specified 2006-2010 RAV4 production and addresses liquid fuel entering the EVAP system. The documented gates are an illuminated MIL with DTC P043E, P043F, P2401, P2402 and/or P2419, or an intermittent warm rough idle reproduced while commanding the purge VSV, followed by physical confirmation of fuel in the applicable EVAP vent hoses. It is not a general 2001-2012 charcoal-canister failure card and does not support the old P0440/P0441/P0442/P0446/P0455 mapping.
Toyota Sienna(1 issue)
- EVAP System Leak-Detection / Vapor Canister Fault (Check Engine Light, Hard Refueling)2011-2020
Third-generation Siennas commonly throw EVAP (evaporative emissions) faults as the system ages. Failure points include the canister vent solenoid/VSV sticking, the leak-detection pump and reference orifice, the purge valve, and a worn or loose gas cap. Beyond the check engine light and an emissions/smog failure, a stuck-closed vent can make the tank hard to refuel (pump clicks off repeatedly), while a stuck-open vent or cracked line can produce a fuel-vapor smell.
