DTC P3190 Poor Engine Power; DTC P3191 Engine does not Start; DTC P3193 Fuel Run Out: Description

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 for the specific duration calculated by water temperature, an abnormal condition is detected.

DTC DETECTION CONDITION

DTC No.	DTC Detection Condition	Trouble Area
PP3190	Following conditions continue at a fixed engine RPM or a fixed length of time: Communication with HV ECU is normal Engine RPM is a fixed value or more Engine start mode is not active Target torque is a fixed value Ratio of estimated torque against target torque is less than 20%	Air induction system Throttle body Fuel pressure Engine Mass Air flow meter Out of fuel Engine coolant temperature sensor Crankshaft position sensor Camshaft position sensor ECM
PP3191	Following conditions continue at a fixed engine RPM or a fixed length of time: Communication with HV ECU is normal Engine RPM is a fixed value or more Engine start mode is not active	Air induction system Throttle body Fuel pressure Engine Mass Air flow meter Out of fuel Engine coolant temperature sensor Crankshaft position sensor Camshaft position sensor ECM
PP3193	Following conditions are met: Fuel low level signal input into ECM Detection condition for P3190 or P3191 is satisfied	Out of fuel ECM
