WHEN I BRAKE THE STEERING SHAKES ALOT
My 2010 Toyota Hybrid has Diagnostic Trouble Code P3065 and I am not sure what it is. What does this code mean?
There are engine codes and battery codes. The battery they are referring to is the Hybrid battery. This code is related to the battery.
If the temperature indicated by the battery temperature sensor is lower than the standard level (open), or is higher than the standard level (short), the battery smart unit interprets this as a sensor malfunction. If the battery smart unit detects that the HV battery temperature is out of normal range or its value is abnormal, the HV control ECU will illuminate the MIL and set a DTC.
Toyota Code P3065
Hybrid Battery Temperature Sensor Range
Code P3065 Description
The battery temperature sensors are provided at 4 locations on the bottom of the HV battery. The resistance of the thermistor, which is built into each battery temperature sensor, varies in accordance with changes in the HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature. the lower the resistance. The battery smart unit uses the battery temperature sensors to detect the HV battery temperature, and sends the detected values to the hybrid vehicle control ECU. Based on the se results, the hybrid vehicle control ECU controls the blower fan.(The blower fan starts when the HV battery temperature rises above a predetermined level.)
