Drive with caution — fix soon.
This code means the voltage signal from turbocharger boost sensor A is lower than expected, which usually points to a short to ground, a wiring fault, or a failed sensor. Sometimes a disconnected or damaged connector is the culprit. It's a common turbo code and is typically fixed by repairing wiring or replacing the boost sensor.
$100 – $400
Varies by vehicle and root cause.
Short trips are usually fine, but the car may feel weak because it limits power for protection. Avoid hard acceleration and towing, and get it looked at soon.
Typically $100 to $400. A simple sensor swap is cheaper, while chasing down a wiring short or harness damage costs more in labor.
It's moderate. You're unlikely to be stranded immediately, but driving with it can mean ongoing reduced power, so don't ignore it for long.
Not always. A low signal can come from the sensor itself or from a wiring short, a bad ground, or a loose connector, so the wiring should be checked before replacing parts.
