DTC P3190-00: Poor Engine Power; DTC P3191-00: Engine does not Start [06/2020 - 08/2020]: Description
WARNING: This page is about a different variant/trim than selected.
The ECM receives signals from the hybrid vehicle control ECU assembly 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.

Poor Engine Power |
When all of the following conditions are met (1 trip detection logic):
- The engine speed is 650 rpm or more (varies depending on the engine coolant temperature).
- Engine torque requested by the hybrid vehicle control ECU exceeds a certain value.
- The hybrid vehicle control ECU assembly judges that the engine has started.
- The fuel tank is not empty.
- Communication between the hybrid vehicle control ECU assembly and ECM is normal.
- The actual engine torque is less than 20% of the requested engine torque for 6 seconds, or until the crankshaft rotates 100 times (whichever takes longer, differs depending on the engine coolant temperature).

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