The code indicates that the throttle position sensor signal to the PCM is intermittent, meaning the voltage from the sensor is sometimes out of expected range or missing.
The sensor can develop internal intermittent failures that cause voltage spikes or drops outside the normal range.
Corroded pins, broken wires, or a loose connector between the sensor and PCM can create intermittent signal loss.
If the sensor's reference voltage or ground is compromised, the signal may become erratic.
A rare PCM failure can misinterpret the sensor signal, but this is usually considered only after other causes are ruled out.
In most cases the PCM does not need replacement; the problem is usually a faulty sensor or wiring issue.
The vehicle may still run, but you could experience throttle hesitation or stall, so it should be addressed promptly.
No, the throttle position sensor monitors the throttle plate angle, while the accelerator pedal sensor monitors pedal position.
Yes, after fixing the underlying issue the code should be cleared with a scan tool or by disconnecting the battery for a short period.
