Overview

The turbocharger solenoid valve is the ECU's boost control valve: on command from the engine control unit, it regulates the wastegate — the exhaust bypass valve of the turbo — and generates the control pressure that decides when the wastegate opens, based on boost pressure and atmospheric pressure. When the valve sticks or fails, boost control goes with it: the check engine light usually comes on, and the engine can lose power or run with erratic boost. This AUXITO solenoid valve is a direct plug-and-play replacement for the applications below.

Features

ECU-controlled boost regulation
Works on ECU commands to control the opening of the exhaust bypass valve and build the control pressure from boost pressure and atmospheric pressure, keeping boost where the engine wants it.

Metal and ABS construction
Made of metal and quality ABS for a long service life and stable, reliable performance.

Direct replacement
Plug and play at the original connector and mounting points — 100% inspected before shipping.

Fitment check

Compare the number on your original valve against 18900-5AA-A01 / K6T52372 and the model line above — and make sure the valve, connector and plug look the same as your old part before ordering, to avoid buying the wrong version.

FAQ

What are the signs of a failing turbo solenoid valve?
Loss of power, boost that comes on erratically or not at all, and a check engine light — often with a boost-related trouble code. If the light stays on after replacement, the fault is elsewhere and needs diagnosing.

How do I confirm it fits my car?
Match your model and year against the fitment table, compare the number on your original valve against the OE and interchange numbers above, and check that the connector and plug look the same as on your old part.

Is it really plug and play?
Yes — it goes in at the original connector and mounting points with no drilling or wiring changes.

Does it include the bracket or hoses?
No — the package is the solenoid valve itself. Reuse the original bracket and connections.
