Drive with caution — fix soon.
This code means the turbocharger boost sensor (sensor A) is reading a pressure that doesn't make sense for the current engine conditions. It often points to a faulty boost sensor, a boost leak, a clogged sensor hose, or wiring problems. It's a common turbo-related code and is usually fixable without major engine work, often by cleaning or replacing the sensor.
$100 – $400
Varies by vehicle and root cause.
For short trips, usually yes, but take it easy on the throttle. The car may feel weak because it limits power to protect the turbo, so avoid hard acceleration and towing and get it diagnosed soon.
Most repairs land between $100 and $400. If it's just the boost sensor or a hose, it's on the lower end; tracking down a boost leak or wiring fault can push it higher.
It's moderate. It won't usually leave you stranded right away, but ignoring it can lead to lost power and potential turbo or engine strain, so don't let it linger.
The boost sensor tells the computer how much pressure the turbo is making. If its reading is off, the engine can't manage fuel and boost correctly, which hurts power and efficiency.
