A failing boost sensor can show up as a check engine light, boost-related fault codes or weaker power under load. Before you replace the sensor, rule out a loose connector, cracked boost piping or a leak near the turbo inlet, since those can look the same. If the sensor is the cause, this one replaces an original that wore out or developed an electrical fault.
