DTC P3190 POOR ENGINE POWER

CIRCUIT DESCRIPTION

DTC Detecting Condition:

From the HV ECU, the ECM receives data such as power output required for the engine (required output), estimated torque produced by the engine (estimated torque), engine RPM of control target (target RPM), whether the engine is in start mode or not. Then, based on the required output and target RPM, the ECM calculates a target torque that is to be produced by the engine and compares it with the estimated torque. If the estimated torque is very low compared with the target torque, or the engine start mode continues at the engine RPM or for the duration calculated by water temperature, an abnormal condition is detected.
