I use scanner check obd2 has come p1128 ,p1120 and p1121. I check the error code is throttle body mlfunction. After I take my car go to repaire. He said is ECU proble. He help me change ECU and rest ECU. After no problem. But. I drive the one week the engine light come on. I no idea what problem is come on the engine light. I pay AU 500 but still not fix. I think the problem is my throttle position sensor has problem. If I change the new throttle position sensor can fix this proble?
