DTC P161B ECM/Pcm Internal Error - Torque Calculation: General Description

Comparing actual torque and desired torque, PCM diagnoses calculated torque state. Actual torque keeps lower than desired torque, PCM checks if actual torque is higher than desired torque, dividing condition into two state, dynamic and steady states, PCM applies different diagnosis logic. Because the responses due to this code is similar to that of MAF control error, checking MAF at first.
