Circuit Description

ECM monitors engine torque. It compares actual torque to a calculated torque based on air, ignition timing and air/fuel ratio. If actual torque exceeds calculated torque for more than 10 minutes, this DTC will set and torque limitation will be activated. High torque can be a result of a problem with MAF, ECT or fuel injectors.
