PINPOINT TEST A: DTC C1854 MOTOR TEMPERATURE OUT OF RANGE
A1 CHECK MOTOR TEMPERATURE SENSOR
• Monitor the motor PID TRNTEMP and note the temperature.
• With key OFF, disconnect motor/transaxle C4993 and connect the
Electric Motor/Transaxle Test Box.
• Measure the resistance between the motor temperature ports on the test
box and determine the motor temperature from the following resistance
values below:
Resistances
—493 ohms=493 °C (32°F)
—533 ohms=0 °C (32°F)
—576 ohms=10 °C (50°F)
—598 ohms=20 °C (68°F)
—668 ohms=30 °C (104°F)
—718 ohms=50 °C (122°F)
—769 ohms=60 °C (140°F)
—824 ohms=70 °C (158°F)
—880 ohms=80 °C (176°F)
—939 ohms=90 °C (194°F)
—1000 ohms=100 °C (212°F)
—1063 ohms=110 °C (230°F)
—1129 ohms=120 °C (248°F)
—1197 ohms=130 °C (266°F)
—1268 ohms=140 °C (284°F)
