DTC Descriptor

DTC P16E0

-
Engine Performance - No Torque Detected

Circuit/System Description

This vehicle does not use a 12V starter motor to crank the internal combustion engine. A much more powerful 300V drive motor generator located within the transmission is utilized to crank the engine. The 300V drive motor generator can rotate the engine to operating speed, 800 RPM, within just a few hundred milliseconds. The hybrid powertrain control module can detect a condition where the engine is cranking but does not start or has stalled.

Conditions for Running the DTC

* The vehicle is ON.

* The system voltage is at least 10 V.

* DTC U0100 is not set.

* Engine running.

* Fuel Level is NOT Low.

* No Fuel Level sensor DTCs set.

Conditions for Setting the DTC

The hybrid powertrain control module expected the engine to be supplying torque but no torque is detected.
