Auxiliary Transmission Fluid Pump Inverter Temperature Sensor Performance

Circuit/System Description

This is an internal fault detection of the power inverter module, often referred to as the drive motor generator power inverter module. This fault is handled inside the power inverter module and no external circuits are involved.

Conditions for Running the DTC

* The vehicle is ON or the module is awake.

* Motor temperature is greater than -40°C (-40°F). If motor temperature is less than -40°C (-40°F) at vehicle ON, the drive motor must operate at greater than 20 Nm (14.75 lb ft) for a cumulative time of 1.5 minutes before the DTC will run.

Conditions for Setting the DTC

DTC P1E34

The inverter phase temperature sensor is less than -58°C (-72°F) for 3 seconds. If the fault is detected at the start of a drive cycle the DTC will set after 600 seconds.

DTC P1E35

The inverter phase temperature sensor is greater than 130°C (266°F) for 3 seconds.

DTC P1E36

A 20°C (36°F) difference is observed between the individual inverter phase temperature sensor and the average of the Hybrid Electronics Coolant Temperature and the Transmission Fluid Temperature.

Action Taken When the DTC Sets

DTCs P1E34, P1E35, and P1E36 are Type B DTCs.

Conditions for Clearing the DTC

DTCs P1E34, P1E35, and P1E36 are Type B DTCs.
