If desired torque is calculated much higher than actual torque, ECM senses it and decreases desired torque. Also, ECM sets P061B. The causes of this error are abnormal operation of ECM (RAM,ROM, ALU errors) and hardware malfunction such that actual air flow enters the engine is more than the flow recognized by ECM.
