System: Fuel & Air Metering · Standard: SAE J2012 generic code · Severity: Repair soon
The car will usually keep running, but continued driving risks secondary damage or an emissions failure. Book the repair.
On drive-by-wire vehicles a throttle position fault often puts the engine into a limited-power mode.
Start by reading every stored and pending code, not just this one. A single fault frequently sets three or four codes at once, and the first one in the freeze-frame data is usually the cause while the rest are consequences.
The throttle position sensor circuit is not returning a plausible signal. Throttle Position Sensor Circuit Malfunction is a generic fuel & air metering code defined by SAE J2012, so it carries the same meaning on every OBD-II vehicle.
Repair soon. The car will usually keep running, but continued driving risks secondary damage or an emissions failure. Book the repair.
In rough order of how often they turn out to be the problem: Failed throttle position sensor; Wiring fault; Contaminated throttle body.
