Range/Performance
Condition for fault identification
Test condition:
Engine must be running
Terminal condition: Terminal 15 ON
Voltage condition:
11 V < electrical system voltage < 26 V
Condition for fault memory entry
no invariable debounce time, constant sensor data reading
during engine warm-up produces entry
Action in service
1) Visual inspection of sensor
2) Perform electrical check on sensor and power-supply
wires
2) Test to determine whether the temperature really changes
when the thermostat opens
