Battery Temperature Sensor: Testing and Inspection

2AR-FXE BATTERY / CHARGING: BATTERY THERMOMETER SENSOR: ON-VEHICLE INSPECTION

1. INSPECT AUXILIARY BATTERY THERMOMETER SENSOR

(a) Disconnect the connector from the auxiliary battery thermometer sensor.





(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NOTICE:
* Hold the sensor only by its connector. Touching the sensor may change the resistance value.
* When measuring, the sensor temperature must be the same as the ambient temperature.

HINT
As the temperature increases, the resistance decreases (see the graph).

If the resistance is not as specified, replace the auxiliary battery thermometer sensor.
