Drive with caution — fix soon.
P0223 means the 'B' throttle or pedal position sensor is reading a higher-than-expected voltage. Modern throttle systems use two sensors that must agree, so a high reading on one can trip this code. Causes typically include a faulty sensor, wiring shorts, or connector problems.
$100 – $500
Varies by vehicle and root cause.
Short distances may be okay, but the car can enter limp mode and respond unpredictably. If it feels unsafe, hold off until it's repaired.
Generally $100 to $500, depending on whether it's a sensor, wiring, or a throttle body replacement.
It's moderate. The main concern is reduced power and inconsistent acceleration, so it's best not to delay the repair.
It means the sensor's voltage signal is higher than the computer expects, often pointing to a short or a failing sensor.
