Drive with caution — fix soon.
This code means the third throttle or pedal position sensor (sensor C) is sending a voltage signal that's too high for the conditions. It's commonly caused by a faulty sensor, a short to voltage in the wiring, or a bad connector pushing the signal up. Repairs usually involve testing and replacing the sensor or fixing the wiring, and it's normally a straightforward fix.
$120 – $400
Varies by vehicle and root cause.
Short trips are usually fine, but the car may go into reduced-power mode. Because throttle response is affected, it's best to get it checked promptly rather than 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 change 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 failing sensor, or a connector problem rather than a mechanical issue.
