P0047 on Toyota
Turbocharger/Supercharger Boost Control Solenoid Circuit Low
P0047 on Toyota vehicles indicates turbocharger/supercharger boost control solenoid circuit low. Au7o has documented this code across 1 Toyota model — most commonly on Tundra. The PCM detects low voltage (short to ground or open) on the turbo/supercharger boost control solenoid circuit.
Common Causes of P0047
- •Short to ground in solenoid wiring
- •Failed boost control solenoid
- •Damaged connector
- •PCM driver fault

- Turbocharger Electronic Wastegate Actuator Failure (V35A Twin-Turbo)2022-2025
Third-generation Tundras with the V35A-FTS twin-turbo V6 (both gas and i-FORCE MAX hybrid) commonly throw boost/wastegate fault codes due to failure of the electronic wastegate actuators integrated into the turbo housings. Early 2022 builds were affected by a bad batch of actuators with an internal electrical fault; thermal cycling also fatigues the actuator over time. When the actuator binds or its circuit fails, the ECU cuts boost and drops the engine into reduced-power/limp mode. Because the actuator is part of the turbo housing, Toyota's initial procedure required replacing the entire turbocharger — an extremely labor-intensive job that can require pulling the cab. This is a distinct, separate failure from the metal-debris main-bearing engine-replacement recall.
