P061B Internal Control Module Torque Calculation Performance - General Information

Component Location





General Description

ECM monitors errors through checksum. Every information consists of the combination of 0 and 1, checksum means summing up all values in a row. Thus, errors are recognized comparing checksum value and the memory value at ECM.

DTC Description

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.
