Drive with caution — fix soon.
This code means the second throttle or pedal position sensor (sensor B) is sending a voltage signal that's too high for the conditions. It's commonly caused by a faulty sensor, a short in the wiring, or a bad connector that's pushing the signal voltage up. Fixing it usually means testing and replacing the sensor or repairing the wiring, and it's normally a straightforward repair.
$120 – $400
Varies by vehicle and root cause.
Short trips are usually fine, but the car may go into a reduced-power mode. Because throttle response can be affected, it's best to get it checked promptly instead of driving on it long-term.
Repairs typically range from $120 to $400. Replacing the throttle position sensor is the most common fix, while wiring or connector repairs can vary the price.
It's moderately serious. The car may still drive, but unreliable throttle behavior is a safety concern, so don't leave it unaddressed.
It means the sensor's signal voltage is higher than the computer expects. This usually points to a short to power, a bad sensor, or a connector problem rather than a mechanical issue.
