If your vehicle is producing boost-related engine fault codes, it may be time to replace your diverter valve. This valve, found on the compressor housing, is designed to vent pressurized air when the throttle plate is closed, preventing compressor surge in the process.
This factory replacement unit is a "plumb-back" style, meaning the pressurized air is recirculated into the inlet for silent operation.
Compressor surge and boost-related fault codes can hurt your vehicle's powertrain. Thankfully, URO Parts offers this replacement unit designed to fix these issues.
