I have the check engine light on my dashboard and when I scan with my OBD scanner it shows P0122 and P0300 and on the display unit it shows antipollution fault. Please how do I solve and clear this error code?

The first code may cause the second code. I would change out the throttle bore and then clear the codes which should fix the problem. Also, check the wiring connector at the throttle body to see if it is good shape.

P0122 - Throttle Position Sensor/Switch A Circuit Low Input:

P0300 - Random/Multiple Cylinder Misfire Detected:

Please let us know what happens.
