P0122 - Throttle Position Sensor (TPS) Circuit Low

The Technical Definition: A P0122 code means the voltage signal sent from the throttle position sensor to the Engine Control Module has dropped lower than the expected operational baseline, usually falling below 0.2 volts.

Common Symptoms: Most drivers first notice hesitation or stumbling when pressing the gas pedal. Your vehicle might stall, or there might be little to no acceleration.

Typical Fix: To fix the error code P0122, you should first check the sensor for damage and look at the connections and wiring for any signs of breakage. If the voltage is too low when tested, you will probably need to replace the part.
