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 low for the conditions. It's commonly caused by a faulty sensor, a short to ground in the wiring, or a corroded connector dragging the voltage down. Fixing it usually involves testing and replacing the sensor or repairing the wiring, and it's typically a straightforward repair.
$120 – $400
Varies by vehicle and root cause.
Short trips are usually fine, but the car may go into reduced-power mode. Since throttle response is affected, it's best to get it checked soon 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 vary the price.
It's moderately serious. The car may still drive, but unreliable throttle behavior is a safety concern, so it shouldn't be left unaddressed.
It means the sensor's signal voltage is lower than the computer expects. This usually points to a short to ground, a failing sensor, or a connector problem rather than a mechanical fault.
