Honda 1.5T Turbocharger Actuator K6T52372 | Replaces 18900-5AF-H01, Precise Control

When your Honda 1.5T engine shows sluggish acceleration, noticeable turbo lag, or the turbocharger fault light (e.g., P2261, P0234) on the instrument panel, this usually indicates internal mechanical jam or electronic control failure of the turbo actuator, preventing precise wastegate valve opening control. When functioning normally, it receives ECU signals to drive the motor, real-time control of turbo pressure to ensure stable and efficient intake across conditions. This product is an aftermarket replacement for OEM 18900-5AF-H01, compatible with Honda Civic (2016-2021), CR-V (2017-2022) and Accord (2018-2023) and other models equipped with 1.5T Earth Dreams engine. During installation, use the dedicated tool to calibrate the actuator’s initial position, and check for wear in the turbo linkage to avoid installation errors causing abnormal boost.
