DTC P3190: Poor Engine Power; DTC P3191: Engine does not Start [10/2013 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The ECM receives signals from the power management control ECU such as the requested engine torque, target engine speed and engine cranking status, and controls the engine output based on the target engine speed and requested torque.

DTC No.	DTC Detection Condition	Trouble Area
P3190	When all of the following conditions are met (1 trip detection logic): Engine speed is 650 rpm or more (varies depending on the engine coolant temperature). Engine torque requested by the power management control ECU exceeds a certain level. The power management control ECU judges that the engine has started. The fuel tank is not empty. Communication between the power management control ECU and ECM is normal "The actual engine torque is less than 20% of the requested engine torque" for 6 seconds, or until the crankshaft turns 100 times (whichever takes longer, differs depending on the engine coolant temperature).

P3191	When all of the following conditions are met (1 trip detection logic): Engine speed is 650 rpm or more (varies depending on the engine coolant temperature). The fuel tank is not empty. Communication between the power management control ECU and ECM is normal. After the power management control ECU sends the engine start request signal, it does not detect engine start (generation of engine torque) for 6 seconds, or until the crankshaft turns 100 times (whichever takes longer, differs depending on the engine coolant temperature).
